Abstract
Abstract In this paper, a new anionic metal-organic framework, [In(PBPTTBA)][(CH3)2NH2] (BUT-29) has been synthesized through the reaction of tetratopic acid ligand with double Lewis pyridine sites, 4,4′,4″,4‴-(4,4′-(1,4-phenylene)bis(pyridine-6,4,2-triyl)) tetrabenzoic acid (H4PBPTTBA) and In(NO3)2 · 5H2O and fully characterized by single-crystal X-ray diffraction (SXRD), powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA), infrared spectroscopy (IR), and elemental analysis (EA). BUT-29 can be used as an efficient adsorbent for the selective removal of organic cationic dyes in N,N′-dimethylformamide (DMF) solution. The adsorption capacities of BUT-29 toward methylene blue and crystal violet at 298 K can reach 1119 mg/g and 832 mg/g, respectively. Moreover, the adsorbed dyes can be released in the DMF solution of LiNO3 gradually.
