Carbon dioxide capture and efficient fixation in a dynamic porous coordination polymer.

ABSTRACT: Direct structural information of confined CO₂ in a micropore is important for elucidating its specific binding or activation mechanism. However, weak gas-binding ability and/or poor sample crystallinity after guest exchange hindered the development of efficient materials for CO₂ incorporation, activation and conversion. Here, we present a dynamic porous coordination polymer (PCP) material with local flexibility, in which the propeller-like ligands rotate to permit CO₂ trapping. This process can be characterized by X-ray structural analysis. Owing to its high affinity towards CO₂ and the confinement effect, the PCP exhibits high catalytic activity, rapid transformation dynamics, even high size selectivity to different substrates.
