The major thrust: develop general concepts to synthesize hyper-active materials with high-stability through materials design.
A catalyst to turn over fast, the active site has to be highly reactive, but for the same catalyst to give a sustained turnover it has to be stable – "fast action AND long stability" is the basic requirement whenever we are in pursuit for a fast-acting system for achieving any conversion. It could be –
a phosphor (converts light/electricity to light),
a photosensitizer (converts light to electricity),
a battery material (converts chemical to electrical energy, vice versa),
a sensor (converts chemical/mechanical energy to electrical energy)
or, even a potent drug.
Unlike in natural enzymes, in the systematic development of man-made systems, these two properties (reactivity/fast activity and stability) always opposed each other.
Solving this challenge is the key motivation.
