采用乙醚蒸汽扩散法,由四氟合硼酸四乙腈合铜髣、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275nm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483nm,这归因于金属干扰的配体内部跃迁。
The reaction was carried out using a diethyl ether vapor diffusion method from tetrachloroborate tetrafluoroborate, copper 4,4’-dipyridyl, bis (2-diphenylphosphino) phenyl ether or triphenylphosphine And [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). They were characterized by elemental analysis and single crystal X-ray diffraction. The UV-Vis spectra and corresponding excited state lifetime were also determined. Complex 1 and 2 show better photophysical properties. Under the excitation of UV light at 275 nm, the maximum emission peak positions of solid powder samples are located at 527 and 483 nm, respectively, which are attributed to the intramolecular transitions of metal interfered ligands.
