Abstract

Abstract: In this work, the nonradiative decay process of several N,N-dimethylamino enone derivatives with different limited structures as the electron donating group has been studied in different viscosities and at different temperatures. The variation of nonradiative decay pro cess has been observed in the media with different viscosities and polarities. In nonpolar me dia with lower viscosity,the nonradiative decay is mainly caused by the internal conversion of nπ^*-ππ^*interaction.Whereas in polar media with high viscosity,the internal rotation loss is the majorly nonradiative decay process.

Key words: N,N-dimethylamino enone derivatives, Nonradiative decay process, Fluo recsence quantum yield, Intramolecular charge transfer
