An azo-linked porous triptycene network as an absorbent for CO2 and iodine uptake

An azo-linked porous organic network (Azo-Trip), in which triptycene is incorporated as a building block, has been prepared via a facile Zn-induced reductive homo-coupling reaction. The Azo-Trip exhibits a BET surface area of 510.4 m2 g-1, large carbon dioxide uptake (119.6 mg g-1, 10.8 wt% at 273 K...

Description
Summary:An azo-linked porous organic network (Azo-Trip), in which triptycene is incorporated as a building block, has been prepared via a facile Zn-induced reductive homo-coupling reaction. The Azo-Trip exhibits a BET surface area of 510.4 m2 g-1, large carbon dioxide uptake (119.6 mg g-1, 10.8 wt% at 273 K and 1 bar), as well as good CO2/N2 (38.6) selectivity. The resulting polymer also displays an excellent guest uptake of 238 wt% in iodine vapor and outstanding reversible adsorption of iodine in solution, which is better than the functionalized MIL-53-NH2 and metalloporphyrin-based NiP-CMP.
