摘要: 用吸收光谱、红外光谱、量子化学、溶液状态等方法探讨了三苯甲烷染料的显色反应,发现有机试剂电子云的对称性与显色增敏有直接关系,表面活性剂的引入,使显色剂的电子云分布更趋均匀,增敏效果显著.应用这种推论可圆满地解释表面活性剂的增敏现象.

Abstract: The color reactions of several triphenylmethane dyes were studied by spectropho-tometry, infrared spectrum, quantum chemistry and solution state.The optimum enhancement of sensitivity on color reaction is in relation to the symmetry of electronic cloud for triphenylmethane dye.The basic principle and experimental method of electronic cloud symmetry of the reagents in surfactant micella are used to analyze polycomponent complex.The property of reagents in micella can be deduced and the main reason of sensitization can be predicted.
