摘　　要：本文以紫外可见光谱法和荧光光谱法研究了水溶性的四-(4-甲基吡啶基)卟啉(TMPyP)和四-(4-羧基苯基)卟啉(TCPP)与磺丁醚-β-环糊精(SBE--βCD)形成的超分子体系。结果表明,两种卟啉与磺丁醚-β-环糊精都形成了1∶1的包结物,它们的包结常数分别为1.34×104L.mol-1和1.15×105L.mol-1。In this paper, the supramolecular system of two water-soluble porphyrins （TCPP and TMPyP） with SBE-β-CD has been studied by UV and Fluorescence spectroscopy. The result shows that both TCPP and TMPyP have formed 1：1 inclusion complexes with SBE-β-CD,and their formation constants are 1.34 × 10^4 L·mol^-1 and 1. 15 × 10^5 L·mol^-1, respectively. Their possible inclusion mechanism has been discussed.
