Novel Intramolecular Electron-transfer Equilibrium in a Spatially Interaction Binary System of a Metal-free Porphyrin and a Ruthenium Trichloro Terpyridyl Complex

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