多孔金属有机骨架{[Cu 2（BBTC）（H2O）2]·2DMSO·4 H2O}n（Cu-BBTC，BBTC=1，1′-丁二炔苯− 3，3 ′，5，5 ′-四羧酸酯; DMSO=二甲基亚砜）的溶剂热合成，并对其结构进行了表征。Cu-BPTC具有两种笼状结构的三维fof网络，小笼直径约为14 mm，大笼呈椭圆形孔，轴向约为14.2×22.6 mm。活化后的Cu-BBTC样品在室温下对C2 H2/CH 4和CO2/CH 4具有选择性吸附行为，其Langmuir表面积为1569 m2 g −1。
A porous metal−organic framework {[Cu2(BBTC)(H2O)2]·2DMSO·4H2O}n(Cu-BBTC, BBTC=1, 1′-butadiynebenzene −3,3′,5,5′-tetracarboxylate; DMSO=dimethyl sulfoxide) was solvothermally synthesized from a tetracarboxylate ligand with butynelene functionality and structurally characterized.Cu-BBTCfeatures a three-dimensional fof network with two types of cages, a small cage is about 14 Å in diameter and a large shows an ellipsoidal pore with about 14.2×22.6 Å in axes. The activated sample ofCu-BBTC, with Langmuir surface area of 1569 m2g−1, exhibits selective gas adsorption behavior with respect to C2H2/CH4and CO2/CH4at room temperature.
