Introduction of free radicals into the macrocyclic ring of porphyrins during polymerization of vinylpyrrolidone

Brief Communications


It was found that porphyrins add chain propagation radicals of vinylpyrrolidone and of certain other monomers during radical polymerization. Depending on the structure of porphyrin, the addition may proceed either with disruption of the π-conjugation ring system, or with its retention. The latter is realized when meso-tetraaryl-derivatives of porphyrin are used and can have practical application as a method for grafting porphyrins onto a polymeric carrier. If the polymerization is carried out under long polymeric chain conditions, the porphyrins play the role of a crosslinking agent.
