摘　　要：The meso-tetraarylporphyrin has been anchored to styrene-divinylbenzene copolymers by reaction or meso-tetra(4-hydroxylphenyl) porphyrin with chloromethylated resin under mild condition. A number of polymer transition metal complexes have been prepared with the polymer ligand and metal salts. The polymeric ligand and its complexes have been characterized by electronic spectra, and vibrational spectra. Cyclohexene can be hydrogenated with the polymeric porphyrin palladium complex(P-THPPPd) as catalyst, and its catalytic activity was influenced by the polarity of solvents, the contents of water in ethanol or reaction temperature. However, its catalytic activity was lower for nitro groups, carbonyl groups and olefins with steric hindrance substituents, and showed no activity for aromatic rings under these conditions.The meso-tetraarylporphyrin has been anchored to styrene-divinylbenzene copolymers by reaction or meso-tetra(4-hydroxylphenyl) porphyrin with chloromethylated resin under mild condition.
