| 摘要: 采用乙醚蒸汽扩散法，由四氟合硼酸四乙腈合铜(Ⅰ)、4，4′-联吡啶、二(2-二苯基膦基)苯基醚或者三苯基膦的反应后的二氯甲烷和乙腈混合溶液中，晶化出[Cu2(4，4′-bipy)(POP)2(CH3CN)2(C2H5O)2](BF4)2 (1)和[Cu2(4，4′-bipy)(PPh3)4(CH3CN)2](BF4)2 (2)两种配合物。对它们进行了元素分析和X射线衍射单晶结构表征，同时测定了UV-Vis光谱及相应的激发态寿命。配合物1和2展示了较好的光物理特性，在275 nm紫外光的激发下，固体粉末样品的最大发射峰位分别位于527和483 nm，这归因于金属干扰的配体内部跃迁。 | |

| Abstract: Crystallization from a mixed solution of dichloromethane (CH2Cl2) and acetonitrile (CH3CN) containing copper(Ⅰ) tetrafluroborate, 4,4′-bipyridine (4,4′-bipy) and either bis-[2-(diphenylphosphino)phenyl]ether (POP) or triphenylphosphine (PPh3), by diethyl ether (Et2O) vapour diffusion methods yielded [Cu2(4,4′-bipy)(POP)2(CH3CN)2(C2H5O)2](BF4)2(1) and [Cu2(4,4′-bipy)(PPh3)4(CH3CN)2](BF4)2(2). Both have been characterized through elemental analysis, X-ray diffraction crystal structure analyses, UV-Vis spectroscopy and measurements of excited state lifetime. Complex 1 and 2 exhibit extraordinary photophysical properties. Under excitation of 275 nm, luminescent wavelengths at 527 nm and at 483 nm of the solid state polycrystalline powders of the two complexes were observed, respectively. They are assigned to originate from metal-perturbed intraligand. CCDC: 727759, 1; 727760, 2. | |
