摘要: 近年来,具有分子内共扼的电荷转移化合物用作荧光探针来研究微环境的特性得到较大的发展,由Lout坛Law等提出的p-N,N一二烷基氨基爷叉丙二睛类化合物,其吸收光谱,特别是荧光光谱具有强烈的溶剂极性依赖性,即荧光光谱的峰值波长依赖于所处环境的极性,并有良好的线性关系。

Abstract: A new kind of intramolecular conjugated charge transfer compound-(p-N,N-dimethylaminostyryl)phenyl malonoitrile has been used as a fluorescence probe in this work.The fluorescence spectra of this compound in solvents with different polarities and the fluo-rescence intensity in systems with different viscosities have been studied.A good linear relationship was established between the photophysical properties of this compound and the environment parameters.This compound was used as a fluorescence probe for studingthe molecular assemblies formation in single and mixed surfactant solutions with different concentrations.Some interesting results were obtained and discussed.

Key words: fiuorescence probe, surfactant, molecular assemble, polarity, viscosity
