Copper(I) complexes with chiral phosphine and diimine ligands were synthesized and their chiroptical properties were investigated. The complex containing a twisted diimine ligand and a diphosphine ligand exhibited moderate-intensity emission and circularly polarized luminescence (CPL) with a significant dissymmetry factor, g(em). The signs and intensities in the CPL spectra were observed to be influenced by the dihedral angles of the two pyridine rings in the diimine ligand.
Copper(I) (Cu(I)) complexes bearing chiral phosphine and diimine ligands were prepared, and their chiroptical properties studied. The complex with a twisted diimine ligand and a diphosphine ligand showed moderate -intensity emission and circularly polarized luminescence (CPL) with a considerable dissymmetry factor, g(em). The signs and intensities in the CPL spectra were found to reflect the dihedral angles of the two pyridine rings in the diimine ligand.
