DESCRIPTION
Green chemistry is an important subject that needs to be a part of every chemist's education, as well as a part of the daily routine of the professional synthetic chemist. This talk describes how a new app can be used to bring green chemistry metrics to reaction descriptions, once they are captured in a proper cheminformatics format. It also describes some of the additional data resources that can be incorporated into the user experience, and how this helps both students and professionals.

MOLECULAR MATERIALS INFORMATICS
• Green chemistry is like a distinct profession: - its own journals, grants, conferences…
• Students need to develop habits early
• Professionals need information access

• … always shown, always stored
• These metrics become as accessible as yield
• Easier to compare & optimise for greenness

Solvents• Choice of solvent has a huge
impact on green profile
• Curated data regarding:

Feedstocks
• Not all starting materials are created equal
• Some can be made from renewable sources
• Lab notebook is a chance to guide & educate
• Curation is a work in progress…

Transforms
• Chemical reactions can be curated as transforms
• Can be used to search for ways to design a reaction
• Curation of green transforms is a way to encourage preferred reaction pathways
