Novel intramolecular electron-transfer equilibrium in a spatially interaction binary system of a metal-free porphyrin and a ruthenium trichloro terpyridyl complex

Temperature-dependent reversible intramolecular electron transfer between a Ru(III)-porphyrin and a Ru(II)-porphyrin pi-cation radical was observed in a novel binary pi-system of a porphyrin and a ruthenium trichloro terpyridyl complex.
