| 摘 要： | 本工作设计并合成了一系列以不同链长相连的芘-对二氰基乙烯基苯(Py-DCVB)化合物, 利用紫外可见吸收光谱、荧光光谱、核磁共振谱研究了Py-DCVB的光诱导分子内电子转移激基复合物的形成与基态构象的关系, 并且利用激光闪光光解开展了盐效应的研究, 瞬态吸收光谱的结果证实了Py-DCVB分子内光诱导电子转移反应经历激基复合物的中间过程。

| Abstract: | In this work, a series of Pyrene-Dicyanovinylbenzene (Py-DCVB) Compounds with different chain length were designed and synthesized. Using absorption, fluorescence and ^1H NMR spectra of Py-DCVB compounds, the relationship between the exciplex formation and the ground state conformation were investigated. Through transient spectra study, the mechanism of intramolecular electron transfer viaexciplex was confirmed by the observation of salt effect. |
