Zn(II),Cd(II)与混合配体构筑三维贯穿金属有机配位聚合物的合成、结构与荧光性能
摘要
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-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.
