STUDIES ON SPECTROSCOPY OF COPPER(I) -PHOSPHINE COMPLEXES

This paper reports the synthesis and characterization of two Cu (Ⅰ ) phosphine complexes CuCl (PPh_3)_3 and Cu_2Cl_2 (PPh_3)_3. It is found that the complexes are photoluminescent. The IR, UV-Vis absorption spectra and emission spectra are investigated. The studies show that the spectroscopic properties are mainly due to the ligand PPh_3, and are not significantly altered upon coordination of Cu-P.
