Pre-design and synthesis of a five-fold interpenetrated pcu-type porous coordination polymer and its CO2/CO separation

Abstract

From the viewpoint of mathematics and topology, we proposed a rational design and stabilized the first five-fold interpenetrated porous coordination polymer (PCP) with a pcu topology and extra-framework volume (60.0%) by employing a linear ligand with the length of ∼2 nm. The resulting compound exhibits good CO₂ uptake, enabling highly selective separation of CO₂ from CO₂/CO mixtures.
