摘要: Photoexcited state of tris(2,2′-bipyridine)ruthenium(II) ion serves as a good reducing agent, if EDTA is present in the solution. Pyridyl radical and 4,4′-bipyridinium cation were obtained by this means photoirradiation, proved to be useful mediators for catalytic reduction Hemin 9,10-anthraquinone-l-sulfonate.
