Molecular Recognition and Chemistry in Restricted Reaction Spaces. Photophysicsand Photoinduced Electron Transfer on the Surfaces of Micelles, Dendrimers and DNA

摘要

This Account is concerned with molecular recognition in bimolecular reactionsthat occur in restricted spaces. Bimolecular reactions of interest are photoinduced electron transfers for which the reactants are positively electronically excited metal complexes and another positively charged gegemon, either a metal complex or methyl viologen that serves as an electron acceptor. The restricted reaction spaces are the interfacial regions of anionically charged polyions such as micelles, starburst dendrimers, and DNA Molecular recognition is concerned with how specific sites on a molecular receptor are recognized by a binding substrate. Knowledge of the underlying principles of molecular
