Abstract:
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.
