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(H_4L)成功地合成出了草酰胺功能化的阴离子骨架材料{[(CH_3)_2NH_2]_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{8~3}_2{8~6}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。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 ） zNH2 ] 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 I 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.
