Abstract
A porphyrin metal complex that can form a stable oxygen complex and acts effectively as an oxygen infusion, which comprises: a transition metal ion M of period 4 or 5 coordinating to a porphyrin derivative represented by the following general wherein R1 is an alicyclic hydrocarbon group which may contain a substituent, R2 is an alkylene group and R3 is a group which does not hinder the coordination of an imidazolyl group to M.

A porphyrin metal complex comprising:
- a transition metal ion M of period 4 or 5 coordinating to a porphyrin derivative represented by the following general formula [I]
- wherein R1 is an alicyclic hydrocarbon group selected from the group consisting of a 1-substituted cyclopropyl group, a 1-substituted cyclopentyl group, a 1-substituted cyclohexyl group, a 1-methyl-2-cyclohexenyl group, a 1-substiuted norbornyl group and a 1-substituted adamatyl group, R2 is an alkylene group and R3 is a group which does not hinder the coordination of an imidazolyl group to M.
A porphyrin metal complex represented by the following general formula [II]:
- wherein M is a transition metal of period 4 or 5, R1 is an alicyclic hydrocarbon group selected from the group consisting of a 1-substituted cyclopropyl group, a 1-substituted evelopentyl group, a 1-substituted cyclohexyl group, a 1-methyl-2-cyclohexenyl group, a 1-substiuted norbomyl group and a 1-substituted adamatyl group, R2 is an alkylene group, R3 is a group that does not hinder the coordination of the imidazolyl group to M, X31 is a halogen ion and n denotes a number obtained by subtracting 2 from the valence number of M.
