摘要

A porphyrin compound represented by the formula [I] [wherein R₁ is an optionally substituted, linear or alicyclic hydrocarbon group; R₂ is alkylene; R₃ is a group which, when an ion (M) of a transition metal in the fourth or fifth period is coordinated, allows the imidazolyl group to coordinate to the central transition metal ion (M); and R is methylene or ethylene] or a metal complex comprising the compound and an ion of a transition metal in the fourth or fifth period coordinated thereto.
