Abstract

Irradiation of a ruthenium polypyridyl complex in the presence of oxygen leads to the oxidation of a benzodipyridophenazine ligand to a quinone. The corresponding tetraazatetrapyridopentacene complex is not oxidized under the same conditions. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
