Abstract
Photolysis, using a visible radiation, of diphthalocyanine complexes o f Nd-III, Dy-III and Lu-III ([Pc(-2>(NdPc)-Pc-III(-2)](-), [Pc(-2)(DyP c)-Pc-III(-2)](-) and [Pc(-2)(LuPc)-Pc-III(-2)](-), respectively) in t he presence of pentachlorophenol (PCP) or SO2 results in the one-elect ron oxidation of the diphthalocyanine species to Pc(-1)(NdPc)-Pc-III(- 2), Pc(-1)(DyPc)-Pc-III(-2) and Pc(-2)(LuPc)-Pc-III(-2), respectively. The PCP is reductively dechlorinated to tetra- and trichlorophenols. The quantum yields for the photosensitization reactions are of the ord er 10(-4). (C) 1997 Elsevier Science Ltd.
