| 摘要: 选用2-(N，N-双(二苯基膦基甲基))胺基吡啶(bdppmapy)为膦配体、二吡啶并[3，2-a∶2′，3′-c]吩嗪(dppz)为氮配体、[Cu (CH3CN)4]BF4为铜盐，在常温下进行反应，制备了3种新型Cu (Ⅰ)配合物，分别为[Cu (dppz)(bdppmapy)]2(BF4)2·H2O (CuBF4-1)、[Cu (dppz)(bdppmapy)]BF4(CuBF4-2)和[Cu (dppz)(bdppmapy)]BF4(CuBF4-3)。获得了CuBF4-1和CuBF4-3的单晶，发现了单晶到单晶转化过程的现象，并探究了溶剂分子的存在对配合物结构和光物理性能的影响。通过单晶X射线衍射确定配合物CuBF4-1和CuBF4-3的结构，使用粉末X射线衍射(PXRD)、红外光谱(IR)和核磁共振氢谱/磷谱(1H/31P NMR)对合成的3个配合物进行结构表征。对配合物进行紫外可见吸收光谱(UV-Vis)、荧光光谱、荧光寿命及量子产率等光物理性质的表征和分析，比较了配合物发光性质的差异，探讨了溶剂分子对配合物结构和光物理性质的影响规律。太赫兹时域光谱对配合物的研究提供了帮助。 |

| Abstract: 2 -(N, N -bis(diphenylphosphino)methyl)aminopyridine (bdppmapy) was selected as a phosphine ligand, dipyrido[3,2-a∶2′,3′-c]phenazine (dppz) as a nitrogen ligand, and [Cu(CH3CN)4]BF4 as a copper salt to react at room temperature. Three new Cu (Ⅰ) complexes were prepared, namely [Cu(dppz) (bdppmapy)]2(BF4)2·H2O (CuBF4 -1), [Cu(dppz) (bdppmapy)]BF4 (CuBF4 -2), and [Cu(dppz) (bdppmapy)]BF4 (CuBF4 -3). Single crystals of CuBF4 -1 and CuBF4-3 were obtained. The phenomenon of single-crystal-to-single-crystal conversion was found, and the influence of solvent molecules on the structure and photophysical properties of coordination geometry was explored. The structures of complexes CuBF4-1 and CuBF4-3 were determined by single-crystal X-ray diffraction, and the structures of the three complexes were characterized by powder X-ray diffraction (PXRD), IR, and hydrogen/phosphorus NMR (1H/31P NMR). The photophysical properties of the complexes were characterized and analyzed by UV-Vis absorption spectrum, fluorescence spectrum, fluorescence lifetime, and quantum yield. The differences in the luminescence properties of the complexes were compared, and the influence of solvent molecules on the structure and photophysical properties of coordination geometry was discussed. Terahertz time -domain spectroscopy provided assistance in the study of complexes. |
