Abstract

Photoinduced electron transfer reactions of [Ru(dmbpy)3]2+ complex with quinones in 50% acetonitrile  and aqueous medium were studied. The complex shows an absorption maximum at 459 nm in 50% aqueous acetonitrile medium and an emission maximum at 605 nm. Emission spectrum were taken for aerated and deaerated sample solutions .The quenching rate constant  kq depends on the nature of the quencher, ligand and also on the nature of the solvent used. Stern-Volmer analysis has been used to find out the quenching rate constant. The results show that molecular oxygen plays an important role with the excited state of the *[Ru(dmbpy)3]2+.
