Abstract: Herein, two novel copper(Ⅰ) complexes,[Cu(PPh3)2(dppz)]I (1) and[Cu2(dppm)2(dppz)2]Cl2 (2) (PPh3=triphenylphosphine, dppz=dipyrido[3,2-a:2',3'-c]phenazine, dppm=bis(diphenylphosphino) methane) have been synthesized, and the characterization of the complexes was carried out through single-crystal X-ray diffraction, elemental analysis, IR, 1H/31P NMR spectroscopy, fluorescence spectra and THz time domain spectroscopy (THz-TDS). The results show that 1 is a mononuclear complex. The central Cu(Ⅰ) builds a distorted tetrahedral geometry by coordinating with two phosphine ligands (PPh3) and one chelating N-donor ligand (dppz). Different from 1,2 exhibits a dinuclear structure which was obtained by the reaction of CuCl and dppm with dppz in 1:1:1 molar ratio, where the diphosphine ligand (dppm) was utilized as a bridging ligand coordinating to two copper(Ⅰ) atoms. The luminescent spectra show that the emission mechanism belongs to metal-to-ligand charge transfer (MLCT). At the same time, the terahertz (THz) time-domain spectroscopy was used to represent these two complexes as well as the corresponding ligands. |
