在甲醇和二氯甲烷的混合溶剂中合成了2个新的铜??配合物:[Cu(dppp)(Bphen)]Cl·1.8CH3OH(1)和[Cu2(CN)2(dppp)(dmp)2]·2.5CH3OH(2)(dppp=1,3-双(二苯基膦基)丙烷,Bphen=4,7-二苯基-1,10-菲咯啉,dmp=2,9-二甲基-1,10-菲咯啉),并通过X射线单晶衍射、元素分析、红外光谱、核磁共振氢谱及磷谱、荧光光谱和太赫兹时域光谱对2个配合物进行了分析和表征.单晶结构表明配合物1是以Cu(Ⅰ)为中心,Bphen和dppp为配体,螯合形成的扭曲四面体结构.配合物2则是由CuCN、dppp和dmp以2:1:2的比例混合得到.配合物2的双膦配体的2个膦基分别与2个Cu(Ⅰ)形成配位键,每个Cu(Ⅰ)又分别与1个氰根和1个dmp配位.发光光谱表明配合物1和2所有的发射峰来源于金属-配体电荷迁移(MLCT).太赫兹时域光谱对配合物1和2的研究提供了帮助.
Two novel Cu(Ⅰ)complexes, [Cu(dppp)(Bphen)]Cl·1.8CH3OH (1) and [Cu2(CN)2(dppp)(dmp)2]·2.5CH3OH (2) (dppp=1,3-bis(diphenylphosphanyl)propane, Bphen=4,7-diphenyl-1,10-diazaphenanthrene, dmp=2,9-dimethyl-1, 10-phenanthroline), have been synthesized in a mixture of CH3OH and CH2Cl2 and characterized by single-crystal X-ray diffraction, elemental analysis, IR, 1H NMR and 31P NMR spectroscopy, fluorescence spectra and terahertz time-domain spectroscopy (THz-TDS). The single crystal X-ray diffraction shows that complex 1 is a distorted tetra-hedral structure with copper as the center, Bphen and dppp as the chelating ligands. Complex 2 is obtained by mixing CuCN, dppp and dmp in a ratio of 2:1:2. The two phosphates of complex 2 form coordination bonds with two Cu(Ⅰ), and each copper coordinates with a cyanogen and a dmp, respectively. The luminescent spectra show that the emission mechanism of complexes 1 and 2 are metal-to-ligand charge transfer (MLCT). The application of THz-TDS also supports to the study of both the complexes.
