Synthesis, characterization, photoluminescence and optical properties of heterobimetallic Cu/Ru hybrid complexes composed of coordination and organometallic sites

► Synthesis of heterobimetallic Cu/Ru hybrid complexes. ► Characterization by elemental analysis and spectroscopic studies. ► Complexes exhibit intra-ligand (π → π∗) fluorescence with high quantum yield. ► Quasireversible redox behavior corresponding to Cu(I)/Cu(II) and Ru(II)/Ru(III) Couple. ► Complexes possess potential application as useful nonlinear optical (NLO) material.
