| 摘 要： | 用荧光光谱的方法研究了由水溶性的中位-四-对-(N,N,N-三甲基苯基)铵基]卟啉的碘化物和2,6,9,15-四(4'-磺酸基)镓酞菁形成的超分子体系,在水溶液中阴离子酞菁与阳离子卟啉能形成杂聚集体。荧光光谱滴定的结果表明:聚集体为杂二聚体,形成平衡常数为1.17×108L/mol。说明了卟啉-酞菁杂二聚体是非常稳定的。没有观察到聚集体的荧光发射。

| Abstract: | The supramolecular system consisting of a water-soluble meso-tetrakis-(P-trimethylphenyl)ammonio] porphyrin tetraiodide and a gallium tetrasodium tetrakis(4’-sul-fonato)phthalocyanine was studied by fluorescence spectroscopy. In water solution,mixing of the anionic phthalocyanine with the cationic porphyrin yields heteroaggregate. The results of fluorimetric titrations indicated that the hetero-aggregate in a heterodimer and the formation equilibrium constant of the heterodimer is 1.17×108 L/mol.The value of the for-mation equilibrium constant indicates that the heterodimer is very stable in water solution.No fluorescense emision of the heterodimer was observed. |
