Exciplex Formation between Silver Ions and the Lowest MLCT Excited State of the Tris(Bipyrazine)Ruthenium(2) Cation

Abstract

The lowest excited MLCT state of the Ru(bpz)32+ cation, is shown to react with silver ion in aqueous or acetonitrile solution to form exciplexes with up to six silver ions per excited cation. Lifetime, wavelength data are presented as a function of the Ag/Ru ratio. An excited state (reductive quenching) potential of 1.55V is derived from quenching by a range of methoxybenzenes. Data for quenching by metal ions are also presented. There is no ground state interaction between 1 and silver ions. Keywords: Excited state, Exciplex, Luminescence, Silver, Ruthenium compounds.
