A new mixed linker metal-organic framework (MOF) has been synthesized from a copper-based metal-organic polyhedron (MOP-1) and 2,2'-bipyridine (2,2'-bipy). The CuMOF-Bipy with a formula of [Cu(2,2'-bpy)(-BDC)] is comprised of a binuclear Cu(II) node coordinated to 2,2'-bipy, and isophthalic acid (-BDC), which bridges to neighboring nodes. The crystal structure of CuMOF-Bipy consists of a stacked two-dimensional framework with the topology. CuMOF-Bipy was characterized by single-crystal X-ray diffraction (SC-XRD), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), and CO sorption. CuMOF-Bipy was shown to have one-dimensional sinusoidal channels that allow diffusion of CO but not N.
一种新型混合连接体金属有机框架（MOF）由基于铜的金属有机多面体（MOP-1）和2,2'-联吡啶（2,2'-bipy）合成。化学式为[Cu(2,2'-bpy)(-BDC)]的CuMOF-Bipy由与2,2'-bipy配位的双核Cu(II)节点以及连接相邻节点的间苯二甲酸（-BDC）组成。CuMOF-Bipy的晶体结构由具有拓扑结构的堆叠二维框架构成。通过单晶X射线衍射（SC-XRD）、X射线光电子能谱（XPS）、热重分析（TGA）和CO吸附对CuMOF-Bipy进行了表征。结果表明，CuMOF-Bipy具有一维正弦通道，可允许CO扩散，但不允许N扩散。
