In this paper are presented absorption and fluorescence emission properties of 3-styrylindoles viz. 3-(2-phenylethenyl-E)-NH-indole (1), 3-[2-(4-nitrophenyl)ethenyl-E)-NH-indole (2), 3-[2-(4-cyanophenyl)ethenyl-E]-N-ethylindole (3) and 3-[2-(4-cyanophenyl)ethenyl-E]-NH-indole (4) in organic solvents, 1,4-dioxane-water binary mixtures and micelles (SDS, CTAB and Triton-X-100). The fluorescence properties of 2-4 have been utilized to probe the microenvironment (binding constant, CMC, micropolarity and solubilization site) of the micelles.
本文介绍了 3-苯乙烯基吲哚的吸收和荧光发射特性，即 3-(2-苯乙烯基-E)-NH-吲哚（1）、3-[2-(4-硝基苯基)乙烯基-E)-NH-吲哚（2）、3-[2-(4-氰基苯基)乙烯基-E]-N-乙基吲哚（3）和 3-[2-(4-氰基苯基)乙烯基-E]-NH-吲哚（4）在有机溶剂、1,4-二氧六环-水二元混合物和胶束（SDS、CTAB 和 Triton-X-100）中的性质。2-4 的荧光性质已被用于探测胶束的微环境（结合常数、CMC、微极性和增溶位置）。
