摘　　要：用光谱法研究了荧光分子2(对己基胺基)苯基3,3二甲基5乙酯基3H吲哚基甲基二十八烷基碘化铵(A)与TritonX100/正庚烷/正己醇/水反胶束间的相互作用。分别测定了A在TritonX100反胶束体系中所处环境的微极性、各向异性参数和pH效应,此外还通过红外吸收光谱考察了水在反胶束中的状态。由以上实验结果得到了有关TritonX100反胶束的结构信息,初步推测了A在该体系中的大致位置。The interactions between a fluorescent molecular probe, i. e., [2-(p-hexylamino) phenyl-3, 3-dimethyl-5-ethoxycarbonyl-3H-indole] methyldioctadecylammonium iodide (A) and Triton X-100/heptane/hexanol/water reverse micelle have been investigated by spectroscopy. Micropolarity of the environment, fluorescence anisotropy parameter and the pH effect of A in Triton X-100 reverse micelle were determined. Furthermore, the state of water in reverse micellar systems was studied by FTIR. According to the above experimental results, some information on the structure of Triton X-100 reverse micelle was obtained and the probable site of A in this system was discussed.
