Designed azo-linked conjugated microporous polymers for CO(2) uptake and removal applications
In recent decade, conjugated microporous polymers (CMPs) were treated as one of the superior porous materials for CO(2) uptake. Herein, we prepared two azo-linked CMPs namely: azo-carbazole (Azo-Cz) and azo-phenothiazine (Azo-Tz) from the reduction of the corresponding nitro monomers using sodium bo...

description | In recent decade, conjugated microporous polymers (CMPs) were treated as one of the superior porous materials for CO(2) uptake. Herein, we prepared two azo-linked CMPs namely: azo-carbazole (Azo-Cz) and azo-phenothiazine (Azo-Tz) from the reduction of the corresponding nitro monomers using sodium borohydride (NaBH(4)). The obtained polymers were well characterized using many spectroscopic techniques. According to TGA and BET analyses, our CMPs owned good specific surface areas (reaching 315 m(2) g(–1)), and a significant thermal stability. It is also possessed pore sizes of 0.79 and 1.18 nm, respectively, and a reasonable char yields (max. 46 %). Based on CO(2) uptake measurements, the CO(2) adsorption capacities of these CMPs were very good: up to 40 and 94 mg g(–1) at the experiment temperatures 298 and 273 K, respectively. The great CO(2) uptake is due to high surface areas that facilitate powerful interactions with CO(2) molecules.
