中文摘要:
      利用钌金属络合物离子和芳香有机二羧酸配体与铀酰离子在水热条件下反应,合成了一例新的异金属有机配位聚合物,也即[Ru(bipy)3][(UO2)2(BDC)3]·2H2O,利用单晶X-射线衍射方法、粉末X-射线衍射方法、红外光谱对该配位聚合物结构进行了基本表征。该配合物是由金属配合物阳离子客体[Ru(bipy)3]2+ 、二维蜂窝状平面结构的聚阴离子主体框架[(UO2)2(BDC)3]n2-之间通过分子内和分子间C-H···O氢键的相互作用形成准三维超分子结构。此外,固体紫外-可见漫反射光谱测试表明此配合物具有半导体性质,是潜在的光电材料。固体荧光测量表明配合物表现出强烈的发光性能。
英文摘要:
      A new heterometallic organic coordination polymer, i.e. [Ru(bipy)3][(UO2)2(BDC)3]·2H2O was synthesized by the reaction of ruthenium metal complex ion ([Ru(bipy)3]2+) and aromatic organic dicarboxylic acid ligand(benzene-1,4-dicarboxylate acid, H2BDC) with uranyl ion under hydrothermal condition. The structure of the coordination polymer was characterized with single crystal X-ray diffraction, powder X-ray diffraction and infrared spectroscopy. Under the [Ru(bipy)3]2+ templates, the complex formed a two-dimensional honeycomb structure with [(UO2)2(BDC)3]2- planar noninterpenetrated honeycomb layer. Intra- and inter-layer hydrogen bonding between the two dimensional honeycomb structure and guest cations contributed to the stabilization of the overall framework. This double layer was eventually connected into a quasi-three dimensional(3D) network. In addition, the solid state UV-Vis diffuse reflectance spectroscopy showed that the complex had semiconductor properties and was a potential photoelectric material. The solid state fluorescence measurement shows that the title complex exhibits strong luminescence.
