【摘要】 金属-有机框架（MOFs）由于其在气体吸附、均相催化、磁性等领域具有潜在的应用价值而被广泛研究[1,2]。MOFs的性能与其拓扑结构有密切联系。采用多样化的有机配体和次级构筑单元（SBU）可有效控制MOFs的拓扑构型。本文中我们基于多齿羧酸配体和含氮配体混配方法构筑了一例三维微孔MOF。该MOF表现为一新型3,4,5-连接拓扑构型,其拓扑学符号为{6³}₂{6⁴·8²}₅{6⁶·8⁴}₂。该三维拓扑结构具有五种不同节点,去掉含氮配体简化的节点后,形成的是一个二维层状结构。更多还原

【Abstract】 As one class of porous materials Metal-organic frameworks（MOFs） have potential applications in gas adsorption,heterogeneous catalysis,magnetism and so on.The properties of MOFs depends much great on their topologies that can be effectively adjusted by combining versatile organic linkers and secondary building units.Here,based on mixed utilization of a polydentate carboxylic acid ligand and a nitrogenous ligand,a microporous three-dimensional MOF was constructed,featured a new3,4,5-connected topologies,with a point symbol of {6³}₂{6⁴·8²}₅{6⁶·8⁴}₂,and there are five different nodes in this structure.When nitrogenous ligand was removed,the structure exhibits a twodimension layer net.更多还原
