摘　　要：通过紫外可见光谱、荧光光谱、一维、二维核磁共振技术等方法确定了β- 环糊精与四- Ｎ- 正丙基吡啶基卟啉包合物的形成．用荧光光谱法测定了包合反应的形成常数，实验结果表明β- 环糊精与四- Ｎ- 正丙基吡啶基卟啉分子形成了摩尔比为2：1的包合物。分子模拟方法进一步证实了该包合物的形成。The inclusion complex of β-cyclodextrin with 5, 10, 15, 20-tetrakis (4-proplpyidinium ) porphyrin bromide was confirmed by UV, fluorescence spectra and NMR, respectively. The formation constant of the inclusion complex was determined by fluorescence spectra. The results indicate that the stoichiometry of the inclusion complex of β-cyclodextrin with 5, 10, 15, 20-tetrakis(4 -proplpyidinium) porphyrin bromide is 2: 1. The molecular modeling provides further evidence for the formation of the inclusion complex.
