Research Abstract

The high valent one-electron oxidized product from an iron(III) porphyrin complex is either the iron(III) porphyrin radical or iron(IV) porphyrin. In this study, we have revealed the existence of novel concept of spin equilibrium between the iron(III) porphyrin radical and iron(IV) porphyrin. We have also found the novel electronic structures of the six-coordinate high-spin iron(III) porphyrin radical without antiferromagnetic coupling and the pure intermediate-spin iron(III) porphyrin radical in the case of one-electron oxidized products.
