Abstract

We report the rates of electron transfer (ET) reactions of electronically excited [Ir(COD)(μ-Me_2pz)]_2 with onium salt photoacid generators (PAGs). The reduction potentials of the PAGs span a large electrochemical window that allows determination of the driving force dependence of the ET reactions. Rate constants of ET from electronically excited [Ir(COD)(μ-Me_2pz)]_2 to onium PAGs are determined by the reaction driving force until the diffusion limit in acetonitrile is reached.
