Abstract

Novel conjugated microporous frameworks based on adamantane (CMF-Ads) have been successfully synthesized under mild conditions. Eight-arm tetraphenyl “knots” and a conjugated π-electron skeleton endowed the target CMF-Ads with ultra-high thermal stability (up to 500 °C), high surface area (up to 907 m2 g−1), excellent CO2 uptake capacity of 15.13 wt % at 273 K and 1 bar, as well as superior organic vapor (benzene, hexane) adsorption. The ultra-high gas uptake capacity and selectivity of these CMF-Ads herein exceeds most conjugated microporous frameworks reported to date, highlighting their potential as materials for clean energy application.
