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 4.5mmol/g (for FC-POP–CH2DETA, 273K, 1bar) 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. ? 2016, The Author(s).
