摘　　要：４－［２－（９，１０－二氰基蒽）乙烯基］－Ｎ，Ｎ－二甲基苯胺的三荧光发射王华，陈景荣，张宝文，曹怡（中国科学院感光化学研究所光化学开放实验室，北京１００１０１）关键词分子内电荷转移，荧光发射从分子水平进行电子转移，电荷分离的研究是十分重要的，它不仅是...The absorption spectrum of DCADMA showed intramolecular charge transfer(CT)interaction between two moieties,DCA and DMA,in the ground state.The triad fluores-cence of DCADMA emits from locally excited(LE)state, intramolecular charge transfer(ICT)state,and twisted intramolecular charge transfer(TICT)state was observed.TheCT emission showed large stokes shift in polar solvent and the dipole moment differenceof excited state and ground state(△μ)for DCADMA is 23.9 Debye.
