Syntheses, Structural Characterizations and Spectroscopic Properties of Two Copper(Ⅱ) Complexes Based on Diphosphine Ligands and [2,3-f ]pyrazino[1,10]phenanthroline

合成了2个新的铜髣配合物,[Cu(dppBz)(dpq)]ClO_4(1)和[Cu(dppe)(dpq)]ClO4(2)(dppBz=1,2-双(二苯基膦)苯,dppe=1,2-双(二苯基膦)乙烷,dpq=[2,3-f]吡嗪并[1,10]菲咯啉),通过X射线单晶衍射分析、元素分析、红外光谱、紫外吸收光谱、荧光光谱、核磁共振光谱和太赫兹时域光谱对其进行了分析和表征。1的中心Cu髣离子通过二亚胺配体和双膦配体共同螯合形成变形四面体结构,2的结构与1类似。配合物2的发光光谱表明它的发光具有金属-配体电荷转移(MLCT)特性。对配合物1和2在0.2～2.8 THz范围内进行了太赫兹时域光谱分析,结果表明0.40～0.90 THz的吸收与中心Cu髣离子的配位有关。

Two novel copper(Ⅱ)complexes[Cu(dppBz)(dpq)]ClO4(1)and[Cu(dppe)(dpq)]ClO4(2)(dppBz=1,2-bis(diphenylphosphino)benzene,dppe=1,2-bis(diphenylphosphino)ethene,dpq=[2,3-f]pyrazino[1,10]phenanthroline)have been synthesized and characterized by X-ray diffraction,elemental analysis,infrared spectroscopy,absorption spectra,luminescent spectra,1 H NMR,31P NMR spectroscopy and terahertz(THz)time-domain absorption spectroscopy.The central Cu(Ⅱ)ion is chelated by a diimine ligand and a diphosphine ligand forming a distorted tetrahedron configuration for 1,and the configuration of 2 is similar to 1.The luminescent spectra of 2 indicated that the emission has metal-to-ligand charge transfer(MLCT)characteristics.The terahertz time-domain absorption spectroscopy analysis in a range of 0.2~2.8 THz showed that the absorption peaks at 0.40~0.90 THz are related to the coordination of the central Cu(Ⅱ).CCDC:1874580,1;1874581,2.
