A new porous coordination polymer (PCP) based on a ligand with a unique bent angle bearing a thiophene-bridged bent carboxylate ligand and the Cu2+ ion was synthesized and structurally characterized. The structure has a pillared-layer framework based on a kagomé-like layer with aromatic partition groups. It exhibits a high CO2 uptake of 180 mL(STP)/g at 1 bar, and 400 mL(STP)/g at 30 bar at 273 K. The uptakes of C2H2 and C2H4 reach 164 and 160 mL(STP)/g at 298 K and 1 bar, with good selectivity of C2H2 and C2H4 over CH4, both of which are among the highest levels of reported PCPs.

使用噻吩基弯曲四羧酸酯配体开发具有高气体容量的多孔配位聚合物

合成了一种新型的多孔配位聚合物(PCP),其基于具有独特的弯曲角度的配体,并带有噻吩桥联的弯曲羧酸酯配体和Cu 2+离子,并在结构上进行了表征。该结构具有柱状层框架,该柱状层框架基于具有芳香族分配基团的类似kagomé的层。它表现出高的CO 2 180毫升(STP)/克的吸收在1巴和400毫升(STP)/ g的在273 K的30巴摄取的C 2 ħ 2和C 2 H ^ 4范围164和160 mL(STP)/ g在298 K和1 bar下,与CH 4相比,C 2 H 2和C 2 H 4的选择性好,这两个都是已报告的PCP的最高级别。
