Single-crystal X-ray diffraction indicates that these complexes show a variety of 1-D (for 2 – 6 ) and 2-D (for 1 ) coordination patterns. The results evidently
摘要 这项工作提出了六种 Cu II 、Co II 、Ni II 和 Zn II 配位聚合物,它们由弯曲的联吡啶配体 4-氨基-3,5-双(3-吡啶基)-1,2,4-三唑(3- bpt) 和丙二酸 (H 2 mal),它们是在环境条件下在水-甲醇溶液中制备的。单晶 X 射线衍射表明这些配合物显示出多种一维(对于 2 – 6 )和二维(对于 1 )配位模式。结果显然揭示了配位组装中具有不同构型和结合模式的3-bpt的多功能性,这将受到金属离子甚至无机抗衡阴离子的深刻影响。此外,扩展的超分子结构是通过多个次级相互作用构建的,例如氢键和芳烃堆积。

were designed, synthesized and well characterized using various analytical and spectroscopic techniques. All the three NDI-PyTz derivatives exhibit decent electronic properties as suggested by DFT, cyclic voltammetry and fluorescence studies. In particular, NDI-PyTz-1 demonstrated the generation of a stable anionradical [NDI-PyTz-1]˙−.

H4L1 guest molecule. Complex4 displays a beautiful 3D porous MOF built by 2D sheetlike [Co2(L1)]n networks pillared by 4-abpt spacers. Complex 5 features a porous 3D MOF with regular nanosized rectangle tunnel. Complex 6 exhibits a 3D structure constructed from a double-layered [Zn2(L2)(H2O)]n network and 4-abpt linker. Complexes 7 and 8 are isostructural 3D polymers completed by 2D [Co1.5/Zn1.5(HL2)(H2O)]n
