Abstract

An in situ approach has been undertaken to synthesize a series of metal-organic frameworks (MOFs) with the pore surface functionalized via the organic linkers of multi N-heterocycles. This was done so as to explore their stability, flexibility, and adsorption behaviors on the basis of the nature of metal centers (M = Zn, Mg, Co, Ni). Four isoreticular MOFs based on in situ synthesized T-shaped ligands were obtained, and their phase purity and stability were investigated in conjunction with the adsorption properties for a wide range of gases (Ar, N 2 , H 2 , CO 2 , CH 4 , C 2 H 6 , C 2 H 4 , C 3 H 8 , and C 3 H 6 ). The results revealed that the stability of MOF based on Ni 2+ is better than those of Mg, Zn, and Co analogues, and that the multi N-heterocycles ligand endows these MOFs with higher affinity for CO 2 , C 2 H 6 , C 2 H 4 , C 3 H 8 , and C 3 H 6 , leading to an excellent selectivity for these gases over CH 4 .
