Structure and Properties of Novel Compounds of Silicon, Germanium and Tin

Abstract

We have concentrated our efforts on the spectroscopy, photophysics, and photochemistry of polysilanes, using a combination of experimental and theoretical tools. We have developed a more detailed version of the chain segment model, have identified and thoroughly characterized the persistent radical formed in UV photolysis, documented further the recently uncovered process of photoinduced chain scission by reductive elimination, and advanced the theoretical understanding of the electronic states of model short-chain oligosilanes. The combined results suggest strongly that the shorter chromophoric chain segments have a different lowest excited singlet state that the longer ones.
