基于柔性的双三氮唑基配体和刚性的芳香羧酸,合成得到了一个一维链状铜配位聚合物[Cu2(bza)4(btx)]n(1)(btx=1,4-二(1,2,4-三唑基-1-基甲基)苯,Hbza=苯甲酸),并通过元素分析、红外光谱、X-射线单晶衍射、热分析、荧光光谱等测试对其进行了表征。晶体数据表明该化合物属于三斜晶系,P1空间群。在化合物1中,羧酸根均采取双齿桥联的模式,4个苯甲酸配体螯合2个铜离子构成1个双核铜单元(Cu-Cu键的距离为0.26 nm),这些双核铜单元又通过柔性双三氮唑基配体桥联形成一维链状的结构;热分析表明该化合物具有相对较高的热稳定性,室温下的固态荧光测试发现,在398 nm激发下,化合物1发射出绿色光。
Based on the flexible bistriazolyl ligands and rigid aromatic carboxylic acids, a one-dimensional chain copper coordination polymer [Cu2 (bza) 4 (btx)] n (1) (1,2,4-triazolyl-1-ylmethyl) benzene, Hbza = benzoic acid) were synthesized and characterized by elemental analysis, IR, X-ray single crystal diffraction, thermal analysis, It was characterized. The crystal data indicates that the compound belongs to the triclinic, P1 space group. In compound 1, the carboxylates all adopt the mode of bidentate bridging, and the four benzoic acid ligands chelate two copper ions to form one dinuclear copper unit (the distance between Cu-Cu bonds is 0.26 nm). These dinuclear copper units And one-dimensional chain structure was formed through bridging of flexible bistriazolyl ligands. Thermal analysis showed that the compound had relatively high thermal stability. The solid state fluorescence test at room temperature showed that under the excitation of 398 nm, compound 1 Emits green light.
