Cobalt（Ⅱ） and Cadimium（Ⅱ） Metal-organic Frameworks Supported by a Multicarboxylate Ligand

论文摘要

Two metal-organic frameworks（MOFs） of formulae [Co7（L）3（4,4?-BPy）2（OH）2（H2O）6]·-4 H2O（1） and [Cd2（L）（2,2?-BPy）2]n（2, H4L = 5-（3,5-dicarboxybenzyloxy）-isophthalic acid,2,2?-BPy = 2,2?-bipyridine, 4,4?-BPy = 4,4?-bipyridine） were synthesized under solvothermal conditions. The structures of 1 and 2 were characterized by X-ray single-crystal diffraction analysis.In complex 1, six cobalt atoms were connected by oxygen atoms to form a defect dicubane structure. The defect dicubane structures were further linked by Co（4,4?-BPy） units to generate a3-D network structure. Compound 2 displays a 2-D chain structure. The photoluminescent property of complex 2 is investigated. The results show the exclusive luminescence emission bands being originated from intraligand π-π* transitions.
