Five metal-organic frameworks, namely, [Mn3(H2DMPhIDC)2(HDMPhIDC)2(bpp)]n (H3DMPhIDC = 2-(3,4-dimethylphenyl)-1H-imidazole-4,5-dicarboxylic acid, bpp = 1,3-di(4-pyridyl)propane) (), [Pb4(DMPhIDC)2(OH)2]n (), [Cd(HDMPhIDC)(en)]n (en = ethylenediamine) (), [Cu3(HDMPhIDC)3(Py)3]n (Py = pyridine) () and {[Zn2(HDMPhIDC)2(Phen)2]2·H2O}n (Phen = 1,10-phenanthroline) () have been hydro(solvo)thermally synthesized and structurally characterized by single-crystal X-ray diffraction, elemental and thermal analyses and IR spectra. Polymer displays a 3D noninterpenetrated framework with 1D open channels. Polymer exhibits a stepped (4,4,4,4,6,6)-connect 2D topology. Polymer is a left-handed helix chain. Polymers and arrange the 3D supramolecular networks containing a 1D corrugated chain via ππ stacking or hydrogen bond interactions. In these MOFs, the imidazole dicarboxylate ligand shows various coordination modes and strong coordination ability. Furthermore, the solid-state luminescent properties of the polymers have also been discussed.
五种金属有机骨架，即[Mn3(H2DMPhIDC)2(HDMPhIDC)2(bpp)]n（H3DMPhIDC=2-(3,4-二甲基苯基)-1H-咪唑-4,5-二羧酸，bpp=1,3-二(4-吡啶基)丙烷）（）、[Pb4(DMPhIDC)2(OH)2]n（）、[Cd(HDMPhIDC)(en)]n（en=乙二胺）（）、[Cu3(HDMPhIDC)3(Py)3]n（Py=吡啶）（）和{[Zn2(HDMPhIDC)2(Phen)2]2·H2O}n（Phen=1,10-菲啰啉）（），通过单晶 X 射线衍射、元素和热分析以及红外光谱对其进行了水（溶剂）热合成和结构表征。聚合物具有 3D 非穿插骨架和 1D 开放通道。聚合物表现出具有 2D 拓扑结构的阶跃（4,4,4,4,6,6）连接。聚合物是一个左手螺旋链。聚合物通过ππ堆积或氢键相互作用排列成包含一维波纹链的 3D 超分子网络。在这些 MOFs 中，咪唑二羧酸配体表现出多种配位模式和强配位能力。此外，还讨论了聚合物的固态发光性质。
