A 3D Tröger's-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 CO uptake abilities as well as good adsorption selectivity for CO over N. The CO storage can reach up to 4.05 mmol g (17.8 wt %) and 2.57 mmol g (11.3 wt %) at 273 K and 298 K, respectively. Moreover, the high selectivity of the polymer toward CO over N (50.6, 298 K) makes it a promising material for potential application in CO separation from flue gas.
一种具有高表面积和良好热稳定性的三维特罗格碱衍生微孔有机聚合物，通过二甲氧基甲烷与三氨基三蝶烯之间的一锅法无金属聚合反应简便合成。所获得的材料显示出优异的一氧化碳吸附能力以及对一氧化碳相对于氮气的良好吸附选择性。在273K和298K时，一氧化碳储存量分别可达4.05 mmol/g（17.8 wt%）和2.57 mmol/g（11.3 wt%）。此外，该聚合物在298K时对一氧化碳相对于氮气的高选择性（50.6）使其成为从烟道气中分离一氧化碳潜在应用的有前景材料。
