Porous organic polymers for CO capture, separation and conversion.

Porous organic polymers (POPs) have long been considered as prime candidates for carbon dioxide (CO) capture, separation, and conversion. Especially their permanent porosity, structural tunability, stability and relatively low cost are key factors in such considerations. Whereas heteratom-rich microporous networks as well as their amine impregnation/functionalization have been actively exploited to boost the CO affinity of POPs, recently, the focus has shifted to engineering the pore environment, resulting in a new generation of highly microporous POPs rich in heteroatoms and featuring abundant catalytic sites for the capture and conversion of CO into value-added products. In this review, we aim to provide key insights into structure-property relationships governing the separation, capture and conversion of CO using POPs and highlight recent advances in the field.
