Research Abstract

Sensitivity of the circularly polarized luminescence instrument has been enhanced. CPL spectra of some palladium(0), platinum(0), and copper(I) complexes were observed for the first time using the instrument. The structures of the complexes have been discussed based on the results of the CPL spectra as well as the CD spectra of the complexes, and the results of quantum chemical calculations. Very strong CPL signal has been obtained for a europium complex bearing tridentate ligands.
