Influence of intermolecular interactions on spectral-luminescent properties of a polyatomic molecule

摘要

A dependence of spectral-luminescent properties of heteroaromatic molecules on interactions with medium is reviewed and discussed. The nonspecific interactions modify, in some cases, an order of electronic states of a different orbital nature. It is shown that, in case of a protic solvent, the energy shift due to the nonspecific interactions is comparable with the energy shift due to the H-bonding. The possible applications of considered concepts are suggested in the field of design of optical chemical sensors.
