Structures and circularly polarized luminescence of copper(I) complexes with chiral diimine and achiral diphosphine ligands

Abstract Copper(I) complexes with chiral diimine and diphosphine ligands were prepared and their chiroptical properties were investigated. By adding chirality to the diimine ligand, CPL (circularly polarized luminescence) intensities emitted from the copper(I) complex were enhanced to a maximum absolute gem value of 3 × 10−3, which is considered large for a mononuclear copper(I) complex.
