【摘要】 由于对人类和环境的严重威胁,染料的吸附已经引起研究工作者的广泛关注。本论文中利用四齿配体5,5’-[oxalylbis（azanediyl）]diisophthalic acid（H₄L）成功地合成出了草酰胺功能化的阴离子骨架材料{[（CH₃）₂NH₂]₂（CdL）}·x（Solvent）（1）。单晶X射线衍射分析表明化合物1具有二重穿插的三维骨架,（3,3,4）-连接的新拓扑网络结构和{8³}₂{8⁶}的点（施莱夫利）符号。更有趣的是,它不仅对亚甲基蓝呈现出选择性的吸附行为,而且在可见光区具有荧光发光性质。更多还原

【Abstract】 Adsorption of dyes has received wide attention due to its threat to human health and environment. In this work,a new oxalamide-functionalized anionic metal-organic framework { [（ CH₃）₂NH₂]₂（ CdL） }·x（ Solvent）（ 1）has been successfully synthesized by virtue of a tetratopic ligand of 5,5’-[oxalylbis（ azanediyl） ]diisophthalic acid（ H₄L）. Single crystal X-ray diffraction reveals that compound 1 exhibits a 2-fold interpenetrated 3D framework and（ 3,3,4）-connected topological network with a new point（ Schlafli） symbol of { 8³}₂{ 8⁶}. Interestingly,it displays not only selective adsorption capacity toward methylene blue（ MB） over methyl orange（ MO）, but also the photoluminescence emission at visible region.更多还原
