Abstract:

An anionic metal organic framework (Me2NH2)2[In2(H4TTBA)2](DMF)(H2O)15 (In-MOF-1; H4TTBA = 2′-amino-[1,1′:4′,1″-terphenyl]-3,3″,5,5″-tetracarboxylic acid, DMF = N,N-dimethylformamide) with suitable channels and PtS-type topology was synthesized and characterized. In-MOF-1 has three types of channels along a, b, c axis that displays the adsorption and selective separation ability toward the low concentration of small cationic dye molecules from water solution at room temperature.

Keywords: Metal organic framework; Dye adsorption and separation; Crystal structure
