摘要/Abstract

摘要： 在许多含氮杂环和芳香族拨基化合物中,能量最低的nπ^*态与能量最低的ππ^*态能级非常接近,这种能级分布往往导致nπ^*态和ππ^*态中能量较低的一个激发态的有效的无辐射失活。这就是能级邻近效应。这种效应被认为是nπ^*和ππ^*两能级间振动相互作用的结果。

关键词: 电荷转移(CT)态, 能级邻近效应, 溶剂化显色效应

Abstract: The dependence of the absorption and fluorescence of charge transfer(CT)state of 3-tricyano vinyl-9-methyl-carbazole (TCVMC)on solvent polarity and temperature is reported. From this study,it is clear that the photophysical properties of TCVMC are controlled simultaneously by the proximity effect and solvatochromism.

Key words: charge transfer (CT) state, proximity effect, solvatochromism
