Abstract

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
