摘　　要：Selective separation of CO_(2)/CH_(4)and C2 H_(2)/CH_(4)are promising for their high-purity industrial demand and scientific research on account of the similar molecular radius and physical properties.In this work,a unique 3 D microporous MOF material[Cu(SiF6)(sdi)2]·solvents(1,sdi=1,1’-sulfonyldiimidazole)was successfully constructed by cross-linking 1 D coordination polymer chains.The dense functional active sites on the inner walls of the channel of la can provide strong binding affinities to CO_(2),C2 H_(2),and thus effectively improve the gas separation performance of CO_(2)/CH_(4)and C2 H_(2)/CH_(4).
