| 摘要: 以4-（2-（4-咪唑）苯乙烯基）吡啶（ISPE）为配体，分别与间苯二甲酸（1，3-H2BDC）、4，4'-联苯二甲酸（4，4'-H2BPDC）和4，4'-二苯乙烯二甲酸（4，4'-H2STDC）及过渡金属盐Cd（NO3）2·4H2O通过溶剂热自组装形成了3种配位聚合物晶体{[Cd2（ISPE）2（1，3-BDC）2]·DMF}n（1）、[Cd（ISPE）（4，4'-BPDC）]n（2）和[Cd（ISPE）2（4，4'-STDC）（H2O）2]n（3）。并用单晶X射线衍射、PXRD、红外光谱、元素分析、热重等对其进行了表征。单晶解析结果表明：配位聚合物1是二维层状网格结构，配位聚合物2是一个六重穿插的类金刚烷三维网格结构，配位聚合物3是由一维网格结构通过氢键和分子间作用力堆积形成的三维网格结构。另外还研究了它们的室温固态荧光性能。 | |

| Abstract: Three new coordination polymers, namely {[Cd2(ISPE)2(1,3-BDC)2]·DMF}n (1),[Cd(ISPE)(4,4'-BPDC)]n (2) and [Cd(ISPE)2(4,4'-STDC)(H2O)2]n (3) have been synthesized by the solvothermal reaction of 4-(2-(4-imidazole)styryl)pyridine(ISPE), Cd(NO3)2·4H2O and 1,3-benzenedicarboxylic acid(1,3-H2BDC), 4,4'-biphenyldicarboxylic acid(4,4'-H2BPDC) and 4,4'-stilbenedicarboxylic acid(4,4'-H2STDC), respectively. These compounds were further characterized by single-crystal X-ray diffraction, PXRD, FT-IR spectroscopy, elemental analysis and TG. Complex 1 has a 2D layered structure. Complex 2 has six-fold interpenetrating 3D diamantane structure. Complex 3 has 3D structure formed by stacking of 1D chains through hydrogen bonds and intermolecular forces. Fluorescence property in the solid state at room temperature was also studied. | |
