Circularly Polarized Luminescence Properties of Heteroleptic Mononuclear Cu(I) Complexes Bearing (R)-BINAP and a Diphosphine-dichalcogenide Ligand

The circularly polarized luminescence properties of heteroleptic Cu(I) complexes bearing (R)-BINAP ((R)-BINAP = (R)-(+)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl) were investigated. When the Cu(I) complexes were combined with diphosphine-dichalcogenide ligands, they displayed the highest dissymmetry factors (glum ≈ 0.005) in the reported Cu(I) mononuclear complexes with emission quantum yields of up to 16% in dichloromethane.
