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)[BPDC: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.
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-bis ( 4-pyri- dyl) ethylene, DMF = N, N-dimethylformamide were synthesized by self-assembly of mixed ligands and corre- sponding 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.
