Abstract

A new porous coordination polymer (PCP) based on a ligand with a unique bent angle bearing a thiophene-bridged bent carboxylate ligand and the Cu 2+ 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 CO 2 uptake of 180 mL(STP)/g at 1 bar, and 400 mL(STP)/g at 30 bar at 273 K. The uptakes of C 2 H 2 and C 2 H 4 reach 164 and 160 mL(STP)/g at 298 K and 1 bar, with good selectivity of C 2 H 2 and C 2 H 4 over CH 4, both of which are among the highest levels of reported PCPs.
