Summary Professor Mark Humphrey is distinguished for his outstanding contributions in developing new types of molecular materials that can modify the propagation characteristics of light. He is a world leader in the construction of p-electron-containing molecular frameworks with embedded ligated transition-metal units and diverse molecular architectures that possess superior “nonlinear optical” (NLO) performance to other materials. His pioneering studies have led to an understanding of how to design molecules with exceptionally large NLO properties, and how to reversibly modulate these properties under the action of external stimuli such as electric potential, other light sources, or chemical triggers such as acidity. The nonlinear optical (NLO) behavior of materials is usually understood as the power dependence of the material polarization with respect to the amplitude of the electric field. This leads to effects such as the generation of new electromagnetic field components that can modify the amplitude, phase, frequency, path, polarization, etc., of the light beams propagating in the nonlinear material. These effects have possible applications in laser technology, data storage, telecommunications, optical signal and image processing, biological imaging, and nanofabrication, and so developing an understanding of how to make efficient NLO materials is of tremendous interest. Professor Humphrey and his group have shown that optimized combinations of ligated-metal units and p-electron delocalizable organic molecular architectures in certain organometallic or coordination complexes afford materials that combine the advantages of organics (fast response times, ease of processing) with greater design flexibility, thermal stability, and enhanced values of the key coefficients that control NLO behavior. He has demonstrated the utility of spectroscopic, electrochemical, and computational aids as predictive tools for efficient NLO materials, and he has prepared organometallic complexes with record large quadratic and cubic NLO coefficients and multi-photon absorption cross-sections. He has shown that metal complexes can function as multi-dimensional NLO switches that are responsive to orthogonal stimuli, and he has developed NLO switches that function across a record number of independently addressable states. Further details are provided below.

Professor Humphrey has a very strong profile and has made exceptional contributions. He leads major research collaborations with France, China, India, and Poland, and collaborates with scientists in many other countries. He has won numerous awards and fellowships for his research, both within Australia and internationally. He has served on the editorial boards of the major organometallic chemistry journals, as well as many journals spanning chemistry, physics, and materials science. He has provided service to the Royal Australian Chemical Institute, both for local members and for national members with interests in inorganic chemistry, and he has chaired/co-chaired sixteen international or national conferences.

Organometallic Complexes for Nonlinear Optics

The advent of lasers in the 1960s led to the discovery that optical properties of materials become dependent on the magnitude of electromagnetic fields in the light beams that interact with them, once the light intensities, and thus the fields, are sufficiently intense. The nonlinear optical (NLO) behavior of materials, usually understood as the power dependence of the material polarization with respect to the amplitude of the electric field, leads to effects such as the generation of new electromagnetic field components able to modify the amplitude, phase, frequency, path, polarization, etc., of the light beams propagating in the nonlinear material. These effects have possible applications in laser technology, data storage, telecommunications, optical signal and image processing, biological imaging, and nanofabrication, and so efficient NLO materials are of tremendous interest.

In sixty-two publications from his group in a series entitled “Organometallic Complexes for Nonlinear Optics”,MGH1-MGH62 as well as sixty publications and reviews describing related syntheses, structural, and optical studies from his group,MGH63-MGH122 and eighty-four publications in collaborations with research groups from a wide range of countries,MGH123-MGH206 Professor Humphrey has demonstrated that transition metal complexes can be highly efficient NLO materials; they can possess very large molecular NLO coefficients that can be reversibly modulated, they can be functionalized for incorporation into readily-processed materials, and they can be designed to be sufficiently robust to resist damage during device manufacture and utilization. His group has optimized molecular performance by developing structure-NLO property relationships; specifically, he has demonstrated the importance of metal valence electron count, ease of oxidation and polarization, the co-ligands about the metal(s), and the p-delocalizable ligands involved in charge-transfer upon quadratic and cubic NLO responses. His studies have also demonstrated the utility of spectroscopic, electrochemical and computational aids as predictive tools for efficient NLO materials. In the process, organometallic complexes with record quadratic and cubic optical nonlinearities and three- and four-photon absorption cross-sections were prepared.

Professor Humphrey’s research has had a particular focus on metal alkynyl complexes with a variety of “multipolar” charge distributions (dipolar, quadrupolar, octupolar). His group rationalized trends in the molecular quadratic NLO coefficients of dipolar metal complexes on varying the alkynyl ligand p-bridge length, solubilizing groups, aryl linking unit stereochemistry and composition, and acceptor group, affording design rules for highly-efficient NLO molecular materials. They also found that quadratic nonlinearities increase upon metal incorporation, upon increasing the metal valence electron count, and upon increasing the ease of oxidation or polarization, while for group 8 metal alkynyl complexes, his group reported an increase in nonlinearity on proceeding from 3d to 4d and then 5d metal, which they showed was consistent with the trend in increasing back-bonding calculated using density functional theory. His group also showed that co-ligand modification can be used to tune the NLO merit. Quadratic nonlinearities for some of his alkynyl complexes are amongst the largest thus far.

Professor Humphrey has reported 1,3,5-triethynylbenzene-cored octupolar and dendritic ruthenium complexes, which have a three-fold symmetry axis, together with linear analogues, the data from which were contrasted with that from the octupolar examples to demonstrate a "dimensional evolution" of NLO properties for the first time (progressing from one-dimensional linear to two-dimensional octupolar). When he commenced these studies, the extant syntheses of dendrimers followed lengthy procedures that frequently involved protection/deprotection protocols. To extend his NLO studies of metal alkynyl complexes from dipolar to octupolar and dendritic compounds, Professor Humphrey developed a new methodology, “steric control”, to rapidly afford the dendrons and then the dendrimers. During this work, he discovered the first example of an NLO “dendritic effect”, namely a nonlinear increase in nonlinearity with increase in dendrimer generation. Professor Humphrey has shown that quadrupolar, octupolar and dendritic ruthenium alkynyl complexes possess very large maximal values of the cubic NLO coefficients. His studies revealed that p-delocalizable organometallic oligomers and dendrimers can have extremely large two-photon absorption (2PA) cross-sections (2PA materials are of interest for a range of applications including microfabrication and imaging). He also reported the first use of electroabsorption to determine cubic nonlinearities of organometallics; analysis of the data for these octupolar complexes indicated that the important excited states responsible for NLO properties are “arm-localized” rather than globally delocalized.

Professor Humphrey’s group reported the first wavelength-dependence studies of cubic and higher-order nonlinearities for organometallic (or indeed inorganic) complexes, and subsequently revealed both a record three-photon absorption (3PA) cross-section for one of his dendrimers, and three-photon absorption-induced photochemistry with another dendrimer (3PA may be superior to 2PA, because its cubic dependence on incident-light intensity leads to superior spatial confinement of the excitation volume and it also affords the possibility of using a much longer excitation wavelength. 3PA is a type of fifth-order (quintic) nonlinearity that is sufficiently rare that structure-property relationships are yet to be established). Recent results have afforded quadrupolar and dendritic examples with record values of three- and four-photon absorption cross-section., the latter an example of seventh-order (septic) nonlinearity for which there are less than ten reports for any kind of material.

The Humphrey group have made a number of major advances in NLO switching. They contrasted the quadratic and cubic NLO activities for vinylidene and alkynyl complex pairs, identifying several examples where interconvertible complexes correspond to protically-switchable NLO materials (the first organometallic examples), and linking the modification in NLO merit to the change in linear optical properties that accompany this reversible addition of electrophiles. Professor Humphrey’s smallest ruthenium complexes have no measurable cubic nonlinearity, but on oxidation an absorption saturation effect is observed, that is, the cubic nonlinearity is switched on - the facile reversibility of this process affords a cubic nonlinearity on/off switch. This aspect of his NLO studies has afforded other “firsts”: he demonstrated the first in situ electrochemical switching of optical nonlinearity, and the first switching of molecular nonlinear absorption. His group showed that these specific NLO effects arise from ps time-scale processes, suggesting that applications involving molecular “switching” of such properties can in principle be exceptionally fast. Professor Humphrey then demonstrated switching between three cubic NLO “states” for the first time, exploiting the widely differing oxidation potentials of the metals in an iron-ruthenium complex, and subsequently showed “orthogonal” switching of NLO properties across three states for the first time (using protic and electrochemical stimuli) in a ruthenium alkynyl cruciform complex. He then demonstrated that a specific dithienylperfluorocyclopentene-bridged bimetallic complex can exist in a record six independently addressable and switchable “states” with distinct linear and NLO properties that can be interconverted by seven distinct pathways exploiting orthogonal protic, electrochemical, and photochemical switching – such complexes have the potential to be used in the construction of multi-input logic gates responding to diverse stimuli across a broad spectral range. These new effects are nonlinear optical analogues of well-established phenomena (halochromism (acidochromism, protochromism), electrochromism, photochromism) in which linear optical properties are modified on application of an external stimulus, and for which materials are already in commercial use (e.g. pH indicators, smart windows, sunglasses, respectively); for the new effects, both nonlinear refractive and nonlinear absorptive “chromisms” were demonstrated by the Humphrey group and therefore have potential application interest.

The difficulty in comparing results for disparate compounds measured in different laboratories using a variety of techniques under different experimental conditions has led Professor Humphrey to explore procedures for scaling NLO data to permit comparisons. His recent results suggest that the NLO efficiencies of organometallics are superior to comparable organics, including when scaled by molecular weight, molecular volume, or cost of production. His research has shown that organometallics can have superior NLO efficiencies to the best organic materials, while possessing additional advantages due to their more facile switching between states with differing (positive/negative or ON/OFF, or positive/zero/negative) NLO responses.

Other research

The vast majority of carbonyl cluster complexes are (a) homometallic or heterometallic incorporating metals from the same or adjacent groups, (b) coordinated by soft donor ligands, and (c) low- or medium-nuclearity in size, the diversity being constrained by the lack of suitable synthetic pathways. Professor Humphrey’s group has addressed this with important contributions to the syntheses and physical properties studies of (a) clusters comprised of very different metal atoms, (b) clusters incorporating hard donor ligands, and (c) high-nuclearity clusters. In a series of thirty-nine publications entitled “Mixed-Metal Cluster Chemistry”,MGH207-MGH245 and a further ten papers from his group describing related structural and optical studies,MGH246-MGH255 his group has explored group 6-iridium clusters, which has involved the synthesis of almost all molecules reported worldwide that possess molybdenum-iridium or tungsten-iridium bonds. A key focus has been examining clusters as

optical limiting materials, an interest that has burgeoned to now incorporate an array of carbon-rich molecules and nanomaterials.

Professor Humphrey’s group has also examined the reactivity of ruthenium clusters towards hard-donor (N-, O-) ligands, which afforded a series of cluster complexes incorporating piperidine, pyridine and phenol residues in varying coordination modes that provide structural models for industrially-important hydrotreating intermediates.MGH256-MGH262 The studies also led to the development of straightforward high-yielding syntheses of high-nuclearity clusters, and the demonstration of their unprecedented reactivity and physical properties.MGH263-MGH276
