合成了5种非水溶性烷氧基苯基卟啉, 以荧光光谱法、紫外可见分光光度法和1H NMR法研究了其与环糊精相互作用形成的超分子体系. 并以荧光光谱法测定了超分子体系的包结常数和包结比, 对其包结机理进行了初步研究. 在此基础上, 探讨了不同取代位置、不同链长的烷氧基对非水溶性烷氧基苯基卟啉与不同空腔直径的环糊精的超分子体系的影响.

关键词: 烷氧基苯基卟啉, 环糊精, 超分子体系, 包结比, 包结常数

Water-unsolvable alkoxyphenylporphyrins were synthesized, and their supramolecular systems with cyclodextrins (CD) have been examined by means of UV-Vis, fluorescence spectrometry and 1H NMR technique. The formation ratio and binding constants of the supramolecular systems were determined by fluorescence spectrometry and an elementary research on its mechanism was performed. The influence of different substituent positions and different lengths of the alkoxy chain on the supramolecular systems of the water-unsolvable alkoxyphenylporphyrin with CD of different cavity diameters was also discussed.

Key words: alkoxyphenylporphyrin, cyclodextrin, supramolecular system, formation ratio, binding constant
