Scheme 4. Photoexcitation and the subsequent relaxation processes of a [Ru(ii)–Re(i)]3+ binuclear complex in the absence of any quencher molecules in solution, i.e., the formation of a triplet metal-to-ligand charge transfer excited state ([3Ru*–Re(i)]3+ and [Ru(ii)–3Re*]3+). Wavenumber values shown are for the RuRe(FPh) complex.
