| Outline of Final Research Achievements |
In this study, several porphyrin derivatives having ring-fused structures at the periphery have been synthesized and their redox behavior has been investigated. A porphyrin derivative having four keto-bridged fused rings exhibited reversible redox behavior between its quinone and hydroquinone forms.
A zinc(II) complex of a quadruply fused porphyrin (QFP), which had a four five-membered fused rings, displayed association with fullerenes even in solution with use of its bowl-shaped distortion and the association constants were determined.
A cobalt(II)-QFP complex performed intramolecular electron transfer from the cobalt center to the porphyrin ligand, which was induced by exchange of the axial ligands from THF to pyridine.
