Abstract:
A Zn(II)-based metal-organic framework [Zn-3(TCA)(2)(DPE)]center dot DMF center dot 6H(2)O (referred to as BUT-161) has been solvothermally synthesized by the reaction of a tritopic carboxylic acid 4,4',4 ''-nitrilotribenzoic acid (H(3)TCA), an ancillary ditopic pyridine ligand 1,2-di(4-pyridyl)ethylene (DPE) and Zn(NO3)(2)center dot 6H(2)O. The framework of BUT-161 shows a pillar-layered structure, where two-dimensional (2D) layers constructed from trimeric Zn-3(-CO2)(6) clusters and TCA(3-) ligands are topologically (3,6)-connected net, and the layers are further pillared by the DPE linkers. The resulting 3D framework contains 1D channels along the b axis. Powder X-ray diffraction (PXRD) patterns and gas adsorption studies reveal that the activated phase of BUT-161, as BUT-161a has permanent porosity with a Brunauer-Emmett-Teller (BET) specific surface area of 308 m(2) g(-1), although the framework structure shrinks (structure transformation) after guest removal. In addition, it has been found that BUT-161a can selectively adsorb CO2 over N-2 or CH4. (C) 2018 Published by Elsevier Ltd.
