Detailed investigations on the heterobinuclear (L)2Ir-dpp-PtCl and homobinuclear [(L)2Ir]2(dpp) compared with the iridium and platinum monometallic counterparts demonstrated that the Ir−Pt and Ir−Ir bimetallic complexes with the same L (C^N) ligand exhibited close similarities in their electrochemical, photophysical, photochemical, and TA decay behavior. We found the nonradiative decay pathway from the emissive charge-transfer state to either the iridium-based d−d or the platinum-based d−d state can be turned efficiently with the energy level tuning of L(π*), generating a different dissociation pattern after photoreaction. |
