Abstract: A series of polymeric metalloporphyrins sensitizers were synthesized with chloro-methylated styrene resins, tetra-(pera-aminophenyl) porphyrin and their metal coplexes. The relative efficiency of photosensitized oxidation for 9, 10-dimethlanthrancene was determined with these sensitizers. The order of the sensitizing ability is: Mg2+ porphyrin > metal-free porphyrin>Cd2+ porphyrin>Ni2+ porphyrin>Cu2+ ponphyrin. The polymeric Mg2+ porphyrin is a good sensitizer for generating 1O2. The others, in particular the porphyrins containdnig paramagnetic Ni2+ and Cu2+, remarkably depress the formation of 1O2.
