新型三维金属-有机配位聚合物的合成、结构与性能

在中温混合溶剂热条件下，分别用镉离子和锰离子与混合多羧酸和多氮配体合成出两个金属-有机配位聚合物M6(TDC)6(hmt)2(DMF)6(H2O)3 ? (H2O)] (JUC-85a, JUC-85b) (M = Cd 或 Mn，TDC = 噻吩-2,5-二羧酸，hmt = 六次甲基四胺，DMF = N,N-二甲基甲酰胺, JUC = Jilin University China)，并通过X射线单晶衍射、元素分析、热重分析、粉末X光衍射、拓扑结构分析和荧光分析对其结构、组成和性质进行了表征. 单晶衍射结果表明，化合物JUC-85a和JUC-85b是同构的三维开放骨架结构，具有一种从少见的(3,6)连接拓扑结构loh1. 同时，JUC-85a具有很好的荧光性质.

Synthesis,Structure and Characterization of Novel 3D Metal-organic Coordination Polymers: [M6(TDC)6(hmt)2(DMF)6(H2O)3·(H2O)](M=Cd,Mn)

Two metal-organic coordination polymers M6(TDC)6(hmt)2(DMF)6(H2O)3 ? (H2O)] (JUC-85a and JUC-85b) (M = Cd or Mn, TDC = Thiophene-2,5-dicarboxylic, hmt = hexamethylenetetramine, DMF = N,N’-dimethylformamide and JUC = Jilin University China) have been synthesized by self-assembly of mixed ligands and corresponding transition metal salts under mild conditions, and characterized by single-crystal X-ray diffraction, elements analysis, TGA, topology analysis, PXRD and photoluminescent. X-ray crystallography reveals that JUC-85a and JUC-85b exhibit the same three-dimensional structure with a rare “loh1” type of (3,6)-connected networks. In addition, photoluminescent of JUC-85a has been characterized.
