A Symposium onSustainable Materials and Light Driven Processes

September 28 and 29, 2012Memorial Union Century Theaterwww.ndsu.edu/chemistry/light

Welcome

Welcome to the Sustainable Materials and Light-Driven Processes Symposium at North Dakota State University. This collaborative effort, involving the Departments of Chemistry and Biochemistry, Coatings and Polymeric Materials, and Physics, along with the Center for Protease Research, is a signatory accomplishment and one that is consistent with a culture at NDSU that places a major emphasis on team research and joint ventures that maximize our resources.

These two days will put on display some of the research that has attracted national and international attention and holds promise for discoveries yet to come. The specific topics brought forth in this symposium are relatively new for NDSU, but it is easy to trace their roots to a long history of seminal work in these departments in both materials and photochemistry. Cutting-edge research demands that we be comfortable with change and uncomfortable with the status quo. So it is also on the broader university level. Recently, NDSU transformed itself from a respected and productive regional university to a university that is now in the highest research classification of the Carnegie Commission on Higher Education, generates 100 doctoral graduates per year, produces nearly 1 percent of the nation’s engineers, and has been cited by Moody’s Investment Services as one of the three reasons, along with energy production and agriculture, that the state of North Dakota has had, arguably, the healthiest economy in the United States for the past 10 years and is projected to be a economic and technology leader in the next decade. Again, welcome to our university. Enjoy this symposium and please accept my apology for not being able to greet you in person.  Philip BoudjoukVice President for Research, Creative Activities and Technology TransferNorth Dakota State University

College of Science and MathematicsThe College of Science and Mathematics prepares NDSU graduates to be part of it all – working in the U.S. and abroad in a wide spectrum of science and mathematics fields. Our graduates serve as top executives in chemical and biotechnology companies, computer scientists for major technology companies (e.g., Microsoft in Fargo), physicists for NASA, physi-cians and health specialists, and exploration geologists at sites across the Americas.

Of the more than 14,000 students attending NDSU, 1,350 undergraduates and 425 graduate students are enrolled in the College of Science and Mathematics. Placement rates for all of our majors are good; our science and mathematics K-12 teachers are in high demand and enjoy the best opportunities in the teaching profession.

NDSU has always been strong in the basic and applied sciences, and the College of Science and Mathematics is involved in all phases of study and research. Research grant awards total approximately $9 million annually. All 120 tenure-track faculty have doctoral degrees and are widely recognized on national and international levels for their professional status and contributions to the new body of scientific and mathematical knowledge. Many of our undergraduate students participate in the research programs of our faculty, and they graduate from NDSU equipped with not only excellent classroom, laboratory and field training, but with sound research experience.

Department of Chemistry and BiochemistryThe Department of Chemistry and Biochemistry has its roots in the founding of the university. On March 8, 1890, the North Dakota Agricultural College was signed into law. Later that year, Edwin Fremont Ladd, a chemist originally from Maine, was recruited to NDSU as one of its first three faculty members. In the basement of College Hall, now known as Old Main, Ladd taught chemistry, paints, cereal chemistry, nutrition and dairy products. He was instrumental in guiding the beginnings of chemistry, pharmacy, nutrition, agricultural biochemistry, polymers and coatings and the State Testing Laboratory at NDAC.

More than 120 years later, the department continues to lead the university and Upper Great Plains region in education and research. More than 7,000 students are taught each year in its general chemistry, organic chemistry and biochemistry courses. The department boasts 19 faculty working in broad research areas from biomedical science to energy to sustainable materials and processes to science, technology, engineering and mathematics education, commonly known as STEM.

With annual research expenditures of more than $3 million per year, the department generates a large economic impact in North Dakota. Since its inception, it has led the state in cutting-edge research in material science, organic, photochemical and photophysical sciences, pharmaceuticals, coatings, catalysis, and agricultural and biomedical sciences. Faculty are globally engaged in research collaborations and partnerships on several continents. State-of-the-art equipment allows students to have the best training in

NMR spectroscopy, X-Ray crystallography, materials characterization, molecular biology, DNA analysis and more. The department hosts collaborative research centers that support research across the colleges and departments at NDSU.

The department proactively engages local high school students and the Fargo-Moorhead community, keeping them informed about modern advancements in science. Each summer the department hosts students in a summer research program called Parents Involvement with Children, Nurturing Intellectual Curiosity in Science, or PICNICS, with the goal of helping local area high school students consider science as a career path.

The department also has a long tradition of nurturing undergraduates in research. The doctoral program trains a dynamic work force capable of tackling research problems faced by scientists at the interface of modern science and technology.

Department of PhysicsThe Department of Physics at North Dakota State University is a relatively “young” department. All 12 faculty have joined the department within the past 11 years with six in the past four years. The department is research oriented with active efforts in theoretical and computational condensed matter physics (advanced simulation techniques, soft matter, complex fluids, active matter and biophysics), electronic properties (photo-excitations and charge transport, Auger charge carrier multiplication and exciton structure in semiconductor quantum dots), optics (laser spectroscopy), physics education, experimental polymer physics (thin films and confinement, adhesion and instabilities), and high-performance polymer nanocomposite films and materials (single-wall carbon nanotubes, graphene and related materials; single-crystal silicon quantum dots and liquid silane inks).

Targeted impact areas related to Sustainable Materials and Light Driven Processes include polymer coatings and composites, energy (photovoltaics and flexible electronics) and biomedical applications of photon-ics. One of our faculty members is director of the Interdisciplinary Graduate Program in Materials and Nanotechnology.

The department also is engaged in outreach activities including the NATURE (Nuturing American Tribal Research and Education) Summer Camp for North Dakota tribal college and high school students, Governor’s School, an Annual Undergraduate Research Poster Session, “Science Fun Nights” at area elementary and middle schools, and NDSU’s “Expanding Your Horizons” for middle school girls. This past year, a team of undergraduate physics majors won a Bronze Medal in the international University Physics Competition.

Department of Coatings and Polymeric MaterialsThe NDSU Department of Coatings and Polymeric materials is one of the few departments in the world with a focus on protective and decorative coatings technology and the one with the longest history. NDSU began offering polymer and coatings chemistry courses in 1906. During the decades, the department has established a worldwide reputation for education and research and enhancing international diversity through interactions between students and research staff with leading companies and universities in the United States and abroad.

The faculty members are highly research active and many have industrial experience. Research programs

are funded by both government and industry and include topics in polymer synthesis, marine coatings, corrosion protection, novel colloidal particles and lifetime prediction.

The department offers an undergraduate minor and M.S. and Ph.D. degrees. Due to the high demand for scientists trained in polymer and coatings technology, our graduates at all degree levels are in high demand and are employed at government laboratories and in major coatings, polymer, chemical, biomedical, electronic and petroleum companies. Many of these graduates have attained upper management positions.

There has been an explosion of interest in upconverters (UC) for device and sensing applications, owing to the introduction of efficient, solvent-dispersible nanocrys-talline UC materials (NaYF4) activated by trivalent lanthanide ions (Ln3+).1 The use of upconverters in a nanocrystalline form dramatically increases their processability, in terms of incorporation into composite materials, and provides high spatial resolution and biocompatibility for sensing applications. However, it is difficult to directly measure the quantum efficiency of these materials, and the effect of materials parameters on efficiency (such as particle size, capping ligand, composite matrix) is poorly understood. A rate-equations model has been constructed which describes the mechanism of NIR-to-visible upconversion in NaYF4 :Er, Yb in terms of the microscopic rate constants relevant to the upconversion mechanism. This model can be used to

determine NIR-to-visible quantum efficiency from accessible spectroscopic data and can isolate the effects of nanoparticle size, doping concentrations, etc. on the individual mechanistic steps. The model correctly predicts the less-than-quadratic dependence of UC intensity on excitation power long before the high power limit is reached. Recent work, illustrated in the figure above, has demonstrated the potential for enhancing upconversion using plasmonic surfaces.2 The use of the kinetic model in characterizing this enhancement will be discussed.

One focus of our research program involves the study of sensitized triplet-triplet annihilation (TTA) or triplet fusion (TF) in solution using highly photostable metal-organic chromophores in conjunction with energetically appropriate organic molecules with large singlet-triplet gaps.1 Selective excitation of the long-wavelength absorbing sensitizer efficiently generates long-lived triplet states that serve as energy transfer donors. In the presence of appropriate molecular acceptors, diffusion controlled triplet-triplet energy transfer takes place, producing the excited triplet state of the acceptor while regenerating the ground state of the sensitizer. When sufficient numbers of the sensitized triplets are produced, TTA takes place which results in either frequency upconverted light or the formation of desired chemical products. Various combinations of donor and acceptor have been explored and data will be presented on a number of these systems spanning light conversions ranging from the near-visible to the near-IR. This presentation also will describe many examples of upconversion phenomena realized in solid-state polymeric materials along with emerging classes of acceptor/annihilator

chromophores.2 TF processes will be shown to operate at high efficiencies with concomitant linear incident power density response, demonstrated in both theory and experiment using non-coherent photons.3 Finally, upconversion-based photoaction observed in water splitting photoelectrochemical cells4 and operational photovoltaics will be discussed.

Colloidal mixtures have attracted much recent attention for their remarkably rich phase behavior. The potential to independently vary macroion size and charge ratios greatly expands possibilities for tuning interparticle interactions and bulk properties. Experiments have begun to explore stability and self-assembly of colloidal mixtures, including colloid-nanoparticle mixtures, which are characterized by

extreme size and charge asymmetries. In modeling such complex soft materials, multiscale methods often prove essential to surmount computational challenges posed by multiple length and time scales. I will report on our recent efforts to develop a hierarchical approach to modeling effective interactions, with the goal of predicting structural and thermodynamic properties of colloid-nanoparticle mixtures.  

BIoGRAPHyAlan Denton is an associate professor of physics at North Dakota State University. He studied engineering science and physics at the University of Toronto and Cornell University before postdoctoral work at the University of Guelph (Canada), the Technical University of Vienna (Austria) and Forschungszentrum Jülich (Germany). His research interests are in theoretical and computational condensed matter physics, emphasizing soft materials (e.g., colloids, nanoparticles, polymers).

In the past decade, a series of useful molecular systems known as phototriggers, photoswitches, photocaging groups, or photoremovable protecting groups (PRPGs) have been used in a wide variety of applications, includ-ing the release of fragrances from household goods, as an aid in multi-step syntheses, and in drug and gene delivery.1 PRPGs also make it possible for biochemists to release bioactive compounds in living tissue with both high temporal and spatial accuracy, thus making it possible to study physiological events such as enzyme activity, ion channel permeability and muscle contrac-tion by ATP hydrolysis. The choice of PRPG is critical,

depends on the system under investigation and must be tailored to the application. Thus, there is a need for new PRPGs that can satisfy the diverse requirements of numerous applications.

We have detected and characterized triplet 1,2-bi-radicals directly in solution by laser flash photolysis of vinylketone derivatives that have a build-in triplet sensitizer. By tethering a triplet sensitizer to the alkene, it is possible to bypass the singlet reactivity of the alkene chromophore and form triplet 1,2-biradicals. The 1,2-biradicals are highly unreactive because they do not react with the solvent but rather decay by intersystem crossing.

We used the 1.2-biradicals to initiate cis-trans isomerization and to photorelease alcohols. We also investigated the solid state reactivity of 1,2-biradicals by doing laser flash photolysis of nanocrystals in water suspension. Thus, we can correlate the solid state reactivity with how the crystal lattice affects the solid state kinetics.

BIoGRAPHyAnna Gudmundsdottir is a professor in the Department of Chemistry at the University of Cincinnati. She earned her Ph.D. at the University of British Columbia under the supervision of Professor John R. Scheffer, studying asymmetric induction in the solid state. Afterward, she was a visiting scientist in the laboratory of Professor Peter Wagner at Michigan State University and investigated radical reactivity. She was a NATO postdoctoral fellow with Professor Matt Platz at The Ohio State University, where is learned to do transient spectroscopy on reactive intermediates.

Gudmundsdottir’s research is focused on studying photoremovable protecting groups (PRPGs) and

solid state reactivity of nitrenes and radicals. Her research team is designing novel PRPGs and study the mechanism for the photorelease. Understanding the reaction mechanism for the photorelease will make it possible to design PRPGs that can be tailored toward specific applications, such as release of fragrances from household goods and for drug delivery. Gudmundsdottir’s group also studies the solid state reactivity of triplet nitrenes with the goal to render them stable so they can be used as building blocks for organic magnets.

Among the honors she has received are a NATO postdoctoral fellowship and NSF CAREER Award. She was elected a fellow of the Graduate School at the University of Cincinnati this spring. She has served as associate editor of Photochemistry and Photobiology since 2011. She also served as co-chair of the Inter-American Photochemical Society meeting (2010) and International Symposium on Reactive Intermediates and Unusual Molecules (2003).

Recent work by our group has demonstrated significant improvements in both the photoluminescence quantum yield of silicon nanocrystals and the energy conversion efficiency of carbon-nanotube based photovoltaic devices through nanoparticle purifica-tion and self-assembly,1,2 where the nanoparticle purification step is performed both in terms of size (for nanocrystalline silicon) and electronic type (for single-wall carbon nanotubes). I will present some of our recent findings related to the harvest and generation of light using these purified carbon and

silicon nanomaterials and discuss both the underlying scientific breakthroughs and the potential applications. I also will summarize our recent progress toward an all-solution-processed nanoscale carbon/silicon photovoltaic device.

Design of scaffolds that induce favorable cellular response as well as promoting cell adhesion, prolifera-tion, differentiation and tissue regeneration is one of the challenges of tissue engineering. Fabrication of scaffolds using polymer composites containing fillers that provide adequate reinforcement along with the required biological signals is one of the strategies to address this challenge. In this work we report the design of novel composite polymer scaffolds with use of novel amino acid modified sodium montmorillonite (Na-MMT) nanoclays. The choice of amino acids is based on a simulation based design guided by the “altered phase theory” for polymer/clay nanocomposites (PCNs) developed by our group. Further the nanoclays galleries are used to mineralize hydroxyapatite and methodology for incorporation of this insitu biomimetic nanoclays-hydroxyapatite into biopolymers is developed. This mineralization route mimics biomineralization in human bone. Our studies with osteoblasts and human mesenchymal stem cells indicate good cell viability and proliferation in addition to exhibiting osteogenic characteristics. We also report simulations of this bio-mimetic nanoclay-hydroxyapatite-polymer system and molecular interactions therein. Representative molecular models are constructed to represent modified clay with HAP and polycapralactone (PCL) polymer composite. Novel nanomechanical testing of cellular responses on biomaterials is also reported using a specially designed nanoindentation fluid cell. The overall experimental and simulations methodology provides new insights into the potential of modified nanoclays in biomaterials.

Using Density Functional Theory (DFT) and Time Dependent DFT (TD-DFT), we investigate the impact of passivating ligands on morphology, electronic structure, and radiative and nonradiative dynamics in CdSe QDs – a topic of general interest due to the recent focus on QD-based solar cells, light-emitting diodes, field-effect transistor, etc. Specifically, we consider the Cd33Se33 cluster passivated by amine and phosphine oxide ligands. Strong QD-ligand interactions result in the development of hybridized states, for which the electronic density is spread over the CdSe cluster and the ligands. Neither the ligand nor hybridized molecular orbitals appear as trap states inside or near the band gap of the QD. Instead, being optically dark,

dense hybridized states open new relaxation channels for high-energy photoexcitations and strongly facilitate exciton relaxation in QDs.

BIoGRAPHySvetlana Kilina earned her bachelor’s and master’s degrees in physics from Belarus State University in 1996 and completed a Ph.D. in physical chemistry at the University of Washington in 2007. She was awarded the Director’s Postdoctoral Fellowship at Los Alamos National Laboratory for 2008-2010. She became assistant professor for the Department of Chemistry and Biochemistry at North Dakota State University in 2010. She established her research group consisting of one postdoctoral associate, three graduate and two undergraduate students. Her group conducts research on computational modeling of processes taking place on organic-inorganic interfaces in hybrid, functionalized nanomaterials. These simulations aim to enhance understanding of how the bio- or organic functional groups, such as dyes, conjugated polymers, DNA, proteins, etc., affect electronic and optical properties, radiative and non-radiative dynamics, charge transfer and transport in such nanosystems as metallic nanoparticles, semiconductor quantum dots and carbon nanotubes.

Mixed-ligand ruthenium complexes are attractive photosensitizers for solar energy conversion because metal-to-ligand charge transfer (MLCT) initiated by visible light can facilitate charge separation to a distant electron acceptor positioned at the end of a functional-ized ligand. Using femtosecond laser spectroscopy, we are investigating how ligand modification affects the ability to direct charge or energy to a desired target. In one study, we have performed broadband femtosecond

transient absorption measurements on a ruthenium polypyridyl complex in acetonitrile solution in which a terminal bipyridinium electron acceptor is connected to the metal center via a p-conjugated linker. Charge transfer to a strongly absorbing state characterized by extensive delocalization of the excited electron throughout the entire p-system is complete on a subpi-cosecond timescale. Charge recombination takes place with a time constant of 1.5 ns, or more slowly than in nearly all other ruthenium-bipyridinium complexes studied to date. In a second study, we have investigated the ultrafast dynamics of ruthenium complexes con-taining variable numbers of bipyridine and phenanth-roline ligands. Linking ruthenium complexes to other active centers requires the modification of at least one ligand, which can change the properties of the excited states used to initiate energy or electron transfer. The complexes studied differ in their excited state dynamics at short time scales, showing that phenanthroline ligands not only change the MLCT energetics, but also affect the dynamics of excited states associated with

Valence Tautomers are compounds having metastable states differentiated by intramolecular electron transfer often combined with a spin crossover. The equilibrium between the two tautomers is entropy-driven and can be altered by a variety of external stimuli. As such, Valence Tautomers have been suggested as useful components of a variety of devices and sensors. This talk will describe a series of such complexes with unprecedented properties and their role as the active layer in spin valves displaying switchable, rectifying behavior.

Photoresponsive Cobalt Bis(dioxolene) valence tautomer Complexes and their Utility in Novel Molecular Spintronic Devices

David A. ShultzDepartment of Chemistry NORTH CAROLINA STATE UNIVERSITY, RALEIGH, N.C.

Organic materials with broadband nonlinear absorp-tion in the visible to the near-IR region are desired for a variety of photonic device applications. Many platinum diimine complexes exhibit broadband excited-state absorption in the visible to the near-IR region. However, due to the very weak ground-state absorption of many reported Pt(II) diimine complexes in the near-IR region, it is not possible to populate the excited state via one-photon absorption in this region. To overcome this disadvantage, we designed and synthesized several series of Pt(II) diimine complexes containing fluorenyl component either on the diimine ligand or on the acetylide ligands to increase the two-photon absorption of these complexes in the near-IR region. In such a case, we can access the excited state via two-photon absorption. Combination of two-photon absorption and excited-state absorption not only expands the nonlinear absorption spectral region but also enhances the nonlinear transmission performance in the near-IR region.

Platinum(ii) Diimine Complexes as Broadband Nonlinear Absorbing Materials

Wenfang SunDepartment of Chemistry and Biochemistry NORTH DAkOTA STATE UNIVERSITY, FARGO, N.D.

As replacements for petroleum-based plastics, environ-mentally-friendly polymeric materials derived from biorenewable feedstocks hold great promise as scien-tists seek to implement green chemistry practices for sustainable technological development. The widespread implementation of biorenewable polymers will require knowledge of the chemistry involved in converting the molecules (natural or engineered) provided by plants into compounds that can readily be converted to new and useful polymeric materials. We address this goal under the rubric of the University of Minnesota Center for Sustainable Polymers, an NSF Phase 1 Center for Chemical Innovation. Interdisciplinary approaches will be described that involve integrated chemical synthesis and structural definition of new monomers, catalysts, and polymers, mechanistic studies of polymerization catalysis, and characterization of the properties of new and useful multiblock polymeric materials.1

Plastics from Plants: Using Metal Catalysts to Make Sustainable Polymers

William B. TolmanDepartment of Chemistry and Centers for Metals in Biocatalysis and Sustainable PolymersUNIVERSITY OF MINNESOTA, MINNEAPOLIS, MINN.

A challenge in designing polymers from bio-based raw materials is to obtain performance properties similar to the current petrochemical based systems. Thermoset-ting polymers are used in a variety of applications including coatings, structural adhesives and compos-ites. Recently, we have discovered that highly functional resins based on epoxidized sucrose esters of vegetable oils can be used in the synthesis of thermosets having outstanding physical and mechanical properties.1 The epoxy groups can be crosslinked directly using cationic photoinitiators or thermal initiators or using crosslinkers such as cyclic anhydrides.2 Studies also have shown that not only is the functionality important, the sucrose itself contributes significantly to the performance properties.3 Further derivatives such as polyols and acrylated resins also can be synthesized and exhibit similar excellent properties when crosslinked.4
