Abstract

UV-vis and fluorescence spectra of 2-[2-(4-cyclaminophenyl)ethen-1-yl] benzothiazoles 1 and their N-allylbenzothiazolium bromides 2 have been measured and interpreted. The substitution and solvent effects on electronic structure and spectra have been investigated. The benzothiazolium salts substituted with saturated cyclamines show strong push-pull character and can be used as potential NLO materials. Formation of aggregated structures was observed at higher concentrations of the benzothiazolium bromides.

摘要

已对2-[2-(4-环胺基苯基)乙烯基-1-基]苯并噻唑1及其N-烯丙基苯并噻唑溴化物2的紫外可见光谱和荧光光谱进行了测量和解释。研究了取代基和溶剂对电子结构及光谱的影响。被饱和环胺取代的苯并噻唑盐表现出很强的推拉特性，可作为潜在的非线性光学材料。在较高浓度的苯并噻唑溴化物中观察到了聚集结构的形成。
