摘要: 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KCl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,计算了二聚平衡的△rHm(这里有图片19980104-15.GIF)和△rSm.

关键词: TPPS, 胶束, 二聚常数, 二聚动力学

Abstract: 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.

Key words: TPPS, Micelles, Dimerization constant, Dimerization Kinetics
