Sign control of circularly polarized luminescence of chiral Schiff-base Zn(ii) complexes through coordination geometry changes

Abstract

The handedness of circularly polarized luminescence (CPL) of Zn(II) complexes with a chiral Schiff-base ligand can be controlled by coordination geometry changes in solution and in the solid state. The relationships between molecular structure and chiroptical properties were discussed with the results of X-ray diffraction analysis and DFT calculations.
