Syntheses,Structures,Luminescence and Magnetic Properties of Three New Metal-organic Frameworks Based on Rigid Carbazole Ligand

Three new metal-organic frameworks [Cd（L）（obba）]·H）2O（1）,[Co（L）（obba）]·MeCN（2） and [Cd_2（L）_2（ip）_2]·6H_2O·DMF（3）（H_2obba = 4,4？-oxybisbenzoic acid,H2 ip = m-phthalic acid） have been successfully synthesized based on the controllable self-assembly of 9-ethyl-3,6-diimidazolyl-carbazole（L）,varied carboxylates and different metal ions under solvothermal conditions,which were characterized by single-crystal X-ray diffraction,elemental analysis,IR spectroscopy and thermogravimetry. Furthermore,luminescence and magnetic susceptibility of compound 2 are also investigated in detail. Single-crystal X-ray diffraction and topology analysis reveal that complexes 1~3 exhibit similar two-dimensional（2D） networks.

杂金属杯[4]配位聚合物的合成与表征（英文）

合成了4个杂金属杯[4]配位聚合物{[Cd(L)(tpa)]·3H_2O}n(1),{[Zn_2(L)_2(tpa)_2]·3H_2O}n(2),{[Co(L)(oba)]·2DMA·0.5H_2O}_n(3)和{[Zn(L)(oba)]·DMA}n(4)(L=2-(1H-咪唑基-甲基)-6-(3-(1H-咪唑基-甲基)-5-叔丁基-2-羟基)苄基-4-叔丁基苯酚,H2tpa=对苯二甲酸,H2oba=4,4′-二苯醚二甲酸),并通过元素分析、热重、红外光谱、固态紫外、单晶X射线衍射和粉末X射线衍射对其进行了表征。单晶结构分析表明晶体1是单斜晶系,P21/n空间群,而晶体2,3和4均为三斜晶系,P1空间群。化合物1,2,3和4是由0维[M(N_4O_2C_(29)H_(36))](M=Zn,Co,Cd)的杂金属杯[4]与配体对苯二甲酸和4,4′-二苯醚二甲酸形成的一维配位聚合物。
