摘要

A porphyrin ring-fusion polymer which consists of two or more ZnII-porphyrin rings fused in a single direction and in which any two porphyrin rings adjacent to each other are fused by three covalent bonds, that is, one meso- meso carbon bond (i.e., one bond between meso-position carbon atoms) and two .beta.-.beta. carbon bonds (i.e., two bonds between .beta.-position carbon atoms adjacent to the meso-position carbon atoms); a process for preparing t he porphyrin ring-fusion polymer regioselectively by conducting the fusion reaction in an aromatic hydrocarbon solvent in the presence of a quinone and a Lewis acid containing a rare earth element under reflux; and fused-ring porphyrin compounds obtained by subjecting the prophyrin ring-fusion polymer to demetallization or replacement of the Zn atoms by other metal atoms.
