Abstract
A series of novel hybrid porous polymers (HPPs) with high specific surface areas were first prepared by one-step ternary cross-linking copolymerization of octavinylsilsesquioxane (OVS), 1,3,5-tribromobenzene, and 4,4´-dibromoazobenzene via the Heck reaction. The porosities and the CO2 uptake capacities of resulting azobenzene-doped porous polymers could be tuned by modulating the molar percentage of the azo units. At 273 K and 101 kPa, the sample with the specific surface area of ~700 m2 g–1 (data of Brunauer—Emmett—Teller (BET) surface area analysis) showed the highest CO2 uptake of 5.45 wt.% (1.20 mmol g–1) among the fabricated HPPs.
