Synthesis of tunable porosity of fluorine-enriched porous organic polymer materials with excellent CO2, CH4 and iodine adsorption.


ABSTRACT: We herein report the construction of four the novel fluorine-enriched conjugated microporous polymers (FCMP-600@1-4), which have permanent porous structures and plenty of fluorine atoms in the skeletons as effective sorption sites. Among them, FCMP-600@4 shows considerable adsorption capacity of CO2 of 5.35?mmol?g-1 at 273?K, and 4.18?mmol?g-1 at 298?K, which is higher than the reported values for most porous polymers. In addition, FCMP-600@1-4 display high selectivity of CO2/N2 and high CH4 uptakes.
