摘要：A porous organic polymer named FC-POP was facilely synthesized with extraordinary porosity and excellent stability.Further covalent incorporation of various amines including single amine group,multi-amine groups of diethylenediamine (DETA),and poly-amine groups of polyethylenimine (PEI) to the network gave rise to task-specific modification of the microenvironments to make them more suitable for CO2 capture.As a result,significant boost of CO2 adsorption capacity of 4.5 mmol/g (for FC-POP-CH2DETA,273 K,1 bar) and the CO2/N2 selectivity of 736.1 (for FC-POP-CH2PEI) were observed after the post-synthesis amine modifications.Furthermore,these materials can be regenerated in elevated temperature under vacuum without apparent loss of CO2 adsorption capacity.
