摘　　要：采用极谱法、紫外可见光谱法及荧光光谱法研究了水溶性卟啉T(4-Mop)PS4与α-CD、-βCD、γ-CD、Hp-β-CD及SBE--βCD 5种环糊精的相互作用,结果表明T(4-Mop)PS4分别与这5种环糊精形成了T(4-Mop)PS4-CD s超分子体系。此外,本研究还采用极谱法、紫外可见光谱法及荧光光谱法测定了T(4-Mop)PS4-CD s超分子体系的包结常数和包结比,比较了T(4-Mop)PS4与5种环糊精的包结能力,并由此推测了包结机理,为T(4-Mop)PS4卟啉、环糊精的进一步应用提供了理论信息。The supramolecular systems of water-soluble porphyrin, meso-terakis （4-methoxyl-3-sulfonato- phenyl） porphyrin （T（4-Mop） PS4 ）, with five cyclodextrins （ CDs）, including α-, β-, γ-cyclodextrin （ α-CD, β-CD, γ-CD）, hydroxylpropyl-β-CD （HP-β-CD）, sulfurbutylether-β-CD （SBE-β-CD）, have been studied by polarography, ultraviolet spectrometry and fluorescence spectrometry. The results show that T（4-Mop）PS4 can interact with the five CDs and form 1 ： 1 supramolecular systems. The inclusion constants of the corresponding supramolecular systems were determined by polargraphy, ultraviolet-visible spectrometry and fluorescence spectrometry, respectively. Furthermore, the inclusion ability of different kinds of CDs with T（4-Mop）PS4 was compared, which provided some elemental data for application of porphyrins and CDs.
