1 Investigating, understanding and (maybe!) controlling how molecules interact The crazy research aims of a Physical Organic Chemist

2 I am a… Post doctoral Research Chemist

3 I am a… Post doctoral Research Chemist - I am a doctor - I know nothing about sick people! - To become a Dr. you do a second degree (but you get paid to do it!) - Doing a Ph.D teaches you to do research

4 I am a… Post doctoral Research Chemist - I am a doctor - I know nothing about sick people! - To become a Dr. you do a second degree (but you get paid to do it!) - Doing a Ph.D teaches you to do research - I try to understand why and how molecules do things - I plan experiments to test ideas and collect information (good and bad!) - I try to apply the information I find - Talk to other scientists

5 I am a… Post doctoral Research Chemist - I am a doctor - I know nothing about sick people! - To become a Dr. you do a second degree (but you get paid to do it!) - Doing a Ph.D teaches you to do research - I try to understand why and how molecules do things - I plan experiments to test ideas and collect information (good and bad!) - I try to apply the information I find - Talk to other scientists - I am interested in molecules and how they interact with each other But so are many physicists and biologists… research is why you are interested and what you do with it!

6 I am interested in how solvents affect molecules and reactions… Normally you need to dissolve reactants to: - make them mix - remove / provide heat - slow other reactions down

7 I am interested in how solvents affect molecules and reactions… People think: But in reality: Normally you need to dissolve reactants to: - make them mix - remove / provide heat - slow other reactions down = solvent

8 I am interested in how solvents affect molecules and reactions… Can affect everything! Colour, product, stability… e.g. a single dye molecule in a range of solvents

9 Most solvents evaporate easily X extremely flammable easy to breathe in difficult to contain and toxic X X X

10 IONIC LIQUIDS are liquid salts and can be used as solvents! Normal solvent Molecule Ionic liquid Ions Do not evaporate - GREEN SOLVENTS Dissolve lots of things Many different ionic liquids I have been investigating how ionic liquids affect things dissolved in them to see if they can replace normal solvents

11 Ionic liquids are just beginning to be used by industry…! Use ionic liquids to make a process more efficient £££££! Green Chemistry can make you money!
