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

MOLECULAR MATERIALS INFORMATICS
Software Can Help
• percentage yield
• atom efficiency
• process mass intensity
• E-factor
3
Calculations Information
• greener solvents
• sustainable feedstocks
• hazardous byproducts
• benign reactions
MOLECULAR MATERIALS INFORMATICS
Mobile App
• Mobile: the platform of the future
• Where the action is: UX/UI innovation
• Where the students are now: iPhones, iPads, etc.
• Needs to be accessible, affordable, simple, effective…

Automatic Green Metrics• Green metrics are always calculated…

• … always shown, always stored
• These metrics become as accessible as yield
• Easier to compare & optimise for greenness
MOLECULAR MATERIALS INFORMATICS
Solvents• Choice of solvent has a huge
impact on green profile
• Curated data regarding:
Safety!Health!Flammability!Environmental impact!Waste disposal!Reactivity!Lifecycle

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…

MOLECULAR MATERIALS INFORMATICS
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
