3 scientists developped a unique amine functionalization strategy, here applied to a novel porous organic polymer that has been synthesized using the molecular building block approach. It was designed to to deliberately encompass aldehyde
functionalities, amenable to post functionalization.
The resultant porous framework allows a facile, unprecedented and anticipated one-step, quantitative, post-synthetic amine functionalization. As envisioned, investigation of CO
2 adsorption properties showed a significant enhancement
of the CO
2 affinity at low coverage versus the pristine material (
Qst increased from 33 to 50 kJ.mol
-1). This feature considerably enriched the CO
2 selectivity and improved the CO
2 removal capabilities from N
2 and CH
4 containing gases akin to post-combustion capture and natural gas upgrading applications.
