摘要:

在中温混合溶剂热条件下, 分别用锌离子和镉离子与二羧酸和二吡啶基配体反应合成出2个新颖的金属有机配位聚合物[Zn(BPDC)(BPE)·(DMF)2](JUC-91)和[Cd(BPDC)(BPE)·(DMF)2](JUC-92)[BP-DC:4,4'-联苯二羧酸,BPE:反式1,2-二(4-吡啶基)乙烯,DMF:N,N'-二甲基甲酰胺], 并通过X射线单晶衍射、 元素分析、 热重分析、 粉末X射线衍射、 拓扑结构分析和荧光光谱对化合物的结构、 组成和性质进行了表征. X射线单晶衍射结果表明, 化合物JUC-91和JUC-92均具有三维开放骨架结构, 其中, JUC-91具有五重贯穿的金刚石拓扑结构, JUC-92具有双重贯穿的简单立方格子结构.

关键词: 金属有机配位聚合物, 4,4'-联苯二羧酸, 反式1,2-二(4-吡啶基)乙烯, 贯穿结构

Abstract:

Two new metal-organic coordination polymers [Zn(BPDC)(BPE)·(DMF)2](JUC-91) and [Cd(BPDC)(BPE)·(DMF)2](JUC-92)[BPDC:4,4'-biphenyldicarboxylic acid,BPE:trans-bis1,2-二(4-pyridyl)ethylene,DMF:N,N'-dimethylformamide] were synthesized by self-assembly of mixed ligands and corresponding transition metal salts under mild conditions and characterized by single-crystal X-ray diffraction, elemental analysis, thermogravimetric analysis, topology analysis and powder X-ray diffraction. X-Ray crystallography revealed that JUC-91 and JUC-92 exhibited three-dimensional structures with fivefold interpenetrating diamond network and twofold interpenetrating primitive cubic network, respectively. In addition, luminescence properties of JUC-91 and JUC-92 were characterized.

Key words: Metal-organic coordination polymer, 4,4'-Biphenyldicarboxylic acid, trans-Bis(4-pyridyl)ethylene, Interpenetrating network
