Abstract

In its most simple form, the energy gap law for excited-state nonradiative decay predicts a linear dependence of ln knr on the ground- to excited-state energy gap, where knr is the rate constant for nonradiative decay. At this level of approximation, the energy gap law has been successfully applied to nonradiative decay in a wide array of MLCT excited states of polypyridyl complexes of ReI, RuII, and OsII. This relationship also predicts a dependence of knr on the structural characteristics of the acceptor ligand. We report here a brief survey of the literature which suggests that such effects exist and have their origin in the extent of delocalization of the excited electron in the ligand π* framework and on acceptor ligand rigidity.
