Porphyrin-phthalocyanine dimer and tetramer having directly-bound Pi electron systems and production method thereof

Abstract

A porphyrin/phthalocyanine dimer represented by the following Formula (A-1) and a tetramer represented by the following Formula (A-2) (where R1, R2 and R3 may be the same or different, and each represents a hydrogen atom or an alkyl or alkyloxy group; M1 and M2 may be the same or different, and each represents two protons or a bivalent or trivalent metal ion; X1 represents a single bond or an alkylene group; X represents —O—, —S—, >NR101 (where R101 represents H or alkyl group), CH2, or a single bond; Y represents 2H, ═O or ═S; m is an integer of 0 to 4; Z represents a five- or six-membered nitrogen-containing coordinating heteroaromatic ring group; provided that the multiple substituent groups represented by the same character may be the same or different.
