Abstract

Abstract : We have successfully designed and synthesized a new tetracarboxylic linker, which constructed its first three‐dimensional microporous metal‐organic framework (MOF), [Cu2 (DDPD)(H2 O)2 ]G x (ZJU ‐13, H4 DDPD=5, 5'‐(2, 6‐dihydroxynaphthalene‐1, 5‐diyl)diisophthalic acid, ZJU=Zhejiang University, G = guest molecules) via solvothermal reaction. Due to open Cu 2+ sites and optimized pore size, the activatedZJU ‐13a displays high separation selectivity for C2 H2 /CH4 of 74 and C2 H2 /CO2 of 12.5 at low pressure by using Ideal Adsorbed Solution Theory (IAST) simulation at room temperature. Abstract : A microporous three‐dimensional metal organic framework with open metal sites and optimized pore sizes was synthesized to realize highly selective C2 H2 /CH4 and C2 H2 /CO2 gas separation.
