引言 Weller最先研究光激发态蒽的荧光可以被三级胺化合物焠灭。随后许多蒽和二甲苯胺或二乙基苯胺体系的研究证明:反应伴随着体系荧光焠灭的同时,出现了一个与形成双分子异激发复合物有关的新荧光峰。由于异激发复合物形成是一个带有电子转移的过程,因此三级胺氮原子上取代基的性质,将对异激发复合物的形成有着重要影响。

INTRODUCTION Weller’s first study of the fluorescence of photoexcited anthracene can be quenched by tertiary amine compounds. Subsequent studies of many anthracene and dimethylaniline or diethylaniline systems demonstrated that the reaction was accompanied by fluorescence quenching of the system and led to a new fluorescence peak associated with the formation of the bimolecular allosteric complex. Since the formation of a heteroleptic complex is a process with electron transfer, the nature of the substituents on the tertiary amine nitrogen atom will have a major impact on the formation of the heteroleptic complex.
