Question

A water-stable twofold interpenetrating microporous mof for selective co2 adsorption and separation

Answer 1

Self-assembly of bent dicarboxylate linker 4, 4′-sulfonyldibenzoic acid (H2SDB) and flexible N, N-donor spacer 1, 4-bis (4-pyridyl)-2, 3-diaza-1, 3-butadiene (L) with Co (NO3) 2· 6H2O forms a twofold interpenetrated {[Co 2 (SDB) 2 (L)]·(H 2 O) 4·(DMF)} n,(IITKGP-6) network via solvothermal synthesis with sql (2, 6 L 1) topology, which is characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, elemental analysis, powder X-ray diffraction (XRD), and single-crystal XRD.
