meso-四(4-磺基苯基)卟啉(TPPS)在水及胶束体系中的二聚行为研究

Studies on the Dimerization of meso-Tetra(4-sulf0phenyl)Prophyrin(TPPS) in the Micelles and KCl Aqueous Solution

研究了meso-四（4-磺基苯基）卟啉（TPPS）在胶束（TritonX－100）、KCl水溶液中的电子吸收光谱变化，计算了TPPS的二聚常数KD，用分光光度法研究了TPPS在KCI水溶液中的二聚反应动力学，提出了与实验结果相吻合的二聚机理．根据温度对二聚平衡的影响。

The change of absorption spectrum of meso-tetra(4-sulfophenyl)porphyrin (TPPS)in micelles, PrOH and KCl aqueous solution was studied. The dimerization constant KD and rate constant k of dimerization reaction of TPPS were measured. It was shown that the KD of TPPS is decreased in micelles and PrOH-H2O solution and increased in KCl solution as compared with that in aqueous solution.
