Abstract: Two novel copper(Ⅰ) complexes[Cu(bdppmapy)(2,2'-bipy)]BF4 (1) and[Cu(bdppmapy)(2,2'-bipy)]I (2) (2,2'-bipy=2,2'-bipyridine, bdppmapy=N,N-bis((diphenylphosphino)methyl)-2-pyridinamine) have been synthesized in mixed solvents of CH3OH and CH2Cl2 (1:1, V/V) and characterized by single-crystal X-ray diffraction, elemental analysis, IR, 1H NMR and 31P NMR spectroscopy, fluorescence spectra and THz time domain spectroscopy (THz-TDS). Complex 1, a mononuclear complex, was generated by the reaction of[Cu(CH3CN)4]BF4 and bdppmapy with 2,2'-bipy in 1:1:1 molar ratio. In complex 1, the central Cu(Ⅰ) forms a distorted tetrahedral geometry by coordinating with the diphosphine ligand (bdppmapy) and chelating N-donor ligand (2,2'-bipy). Like 1, 2 was obtained by the reaction of CuI and bdppmapy with 2,2'-bipy in 1:1:1 molar ratio. In the asymmetric unit of 2, the bdppmapy and 2,2'-bipy ligands chelate central Cu(Ⅰ), respectively. The luminescent spectra show that the emission mechanism is metal-to-ligand charge transfer (MLCT). The application of terahertz time-domain spectroscopy also provides useful information for the research of complexes. |
