Novel metal porphyrin compositions useful as organic phosphors are provided. The novel compositions are prepared from commercially available porphyrin-containing starting materials. In one instance a novel palladium-containing porphyrin composition having a number average molecular weight of greater than 12,000 grams per mole was prepared from 5,10,15,20-tetrakis(3′,5′-di(hydroxy)phenyl)-21H-23H-porphyrin by reaction first with palladium(II) acetylacetonate, followed by reaction with 2-bromo-2-methylpropionyl bromide, and subsequent group transfer reaction of the alpha-bromo ester groups with 9,9-dioctyl-2-vinylfluorene in the presence of CuBr as a radical initiator. The product polymer exhibited a number average molecular weight of 12,884 grams per mole, a weight average molecular weight of 14,338 grams per mole, and a robust red phosphorescent emission. Porphyrin containing copoylmers comprising structural units derived from 9,9-dioctyl-2-vinylfluorene and 9-anthracenylmethyl methacrylate were prepared in a similar fashion.
