Bimetallic coinage metal complexes of type [Me₂(dcpm₂)]²⁺, 1²⁺, (Me= Ag, Au; dcpm = bis(dicyclohexylphosphino)methane) are stabilized by metal-metal interactions and give rise to interesting optical properties for OLEDs, photocatalysis, and sensory applications. Their excited state dynamics have been investigated in parallel in gas phase by femtosecond photo-induced dissociation and in solution by transient absorption. Both studies report a multiexponential electronic decay after excitation of metal-centered states modulated by solvent molecules and counter ions.
