摘要：

Water-soluble porphyrin, tetra-(p-sulfophenyl) porphyrin (H2TPPS), and its metalloporphyrin complex( FeTPPS and ZnTPPS) were synthesized and characterized. The pH control for the reaction system and the use of dialytic bag can efficiently increase the yield and purity of the product. The structural traits and spectral properties were discussed by means of UV-Vis, fluorescence, H-1 NMR and FTIR spectroscopic methods. The results show that the existence of the sulfonic groups enhances the intermolecular pi-pi interaction and the aggregation of the porphyrins. FeTPPS was used as catalyst in 2,4,6-trichlorophenol oxidative dechlorination in the presence of H2O2 as oxidant, FeTPPS/H2O2 system was proved to be an efficient catalysis system and 766 turnover numbers was obtained.
