FMD3 scientists developped a unique amine functionalization strategy to enhance CO2 sorption properties

30 November, 2013

FMD3 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 CO2 adsorption properties showed a significant enhancement of the CO2 affinity at low coverage versus the pristine material (Qst increased from 33 to 50 kJ.mol-1). This feature considerably enriched the CO2 selectivity and improved the CO2 removal capabilities from N2 and CH4 containing gases akin to post-combustion capture and natural gas upgrading applications.
