Abstract
- A superacid-promoted “knitting” strategy has been developed for the generation of a novel family of hypercrosslinked nanoporous polycarbazoles for efficient CO<subscript>2</subscript> capture. Using trifluoromethanesulfonic acid, a Brønsted superacid, we demonstrate the facile and rapid synthesis of highly porous polycarbazoles with BET surface areas as high as 1688 m<superscript>2</superscript> g<superscript>−1</superscript>, and capable of adsorbing 3.5 mmol g<superscript>−1</superscript> of CO<subscript>2</subscript> at 298 K and 1 bar. This impressive result bestows the material with the highest CO<subscript>2</subscript> uptake capacity for all nanoporous carbazolic polymers and ranks among the best by known porous organic polymers under this condition. This innovative approach affords a metal-free alternative to Friedel–Crafts alkylation, and may open up new possibilities for the rational design and synthesis of new hypercrosslinked nanoporous organic networks for carbon capture.
