文摘

A 3D Tr枚ger鈥檚-base-derived microporous organic polymer with a high surface area and good thermal stability was facilely synthesized from a one-pot metal-free polymerization reaction between dimethoxymethane and triaminotriptycene. The obtained material displays excellent CO₂ uptake abilities as well as good adsorption selectivity for CO₂ over N₂. The CO₂ storage can reach up to 4.05 mmol g^鈥? (17.8 wt %) and 2.57 mmol g^鈥? (11.3 wt %) at 273 K and 298 K, respectively. Moreover, the high selectivity of the polymer toward CO₂ over N₂ (50.6, 298 K) makes it a promising material for potential application in CO₂ separation from flue gas.
