A series of water-soluble sulfonated porphyrins have been synthesized and characterized by 1H NMR, IR, UV-Vis, fluorescence and MS. The fluorescence quantum yield and lifetime of the series of porphyrins have been obtained. These porphyrins have been used as photocatalysts for the oxidation of 2,3-dihydroxynaphthalene. The main product has been proved to be 1,2-benzenedicarboxylic acid with the highest conversion rate of 91%. The effects of electron caused by different substituent groups and steric structure on sulfonated porphyrins photocatalytic activities have been investigated. It has been proved that substituent groups have electronic effects on the photocatalytic activities. The chosen of oxygen resource, the kinetics of the oxidation and the photocatalytic mechanism of sulfonated porphyrins have been investigated.

Key words: sulfonated porphyrin, electronic effect, photocatalytic activity, kinetics
