An amino-decorated porous metal-organic framework for efficient C2 Hydrocarbon/CH4 separation and high iodine adsorption

Abstract In this work, a new amino-decorated porous metal-organic framework [Ni(NH2-pba)2]·2H2O·2DMF (NH2-Hpba = 3-amino-4-(pyridin-4-yl)benzoic acid) (1) has been synthesized and structurally characterized. This compound exhibits a class IIIa interpenetration of dia net with a [2 + 2] mode. For its high porosity and amino-decorated channel, this compound shows efficient CO2/N2, C2H4/CH4 and C2H2/CH4 selectivity and high iodine adsorption .
