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。

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(Schläfli) 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.

Key words: anionic framework, new topology, adsorption of methylene blue
