We have shown that one can utilize water soluble nano-containers as supramolecular catalysts to perform selective photochemical reactions. The supramolecular photocatalytic process displays features similar to an enzyme – reaction is allosteric with very minimal product inhibition with good turnover. More importantly, encapsulation of the reactant molecule within the nano-cavity protects the excited state enhancing reactivity. The reaction can be carried out in water with visible light showcasing utility as a green chemical process. Some representative publications/reviews on this topic from our group is below
