A series of novel triazine-containing pore-tunable carbon materials (NT-POP@800-1-6), which was synthesized via pyrolysis of porous organic polymers (POPs) without any templates. NT-POP@800-1-6 possess moderate BET surface areas of 475-736 m g, have permanent porosity and plenty of nitrogen units in the skeletons as effective sorption sites, and display relatively rapid guest uptake of 56-192 wt% in iodine vapour in the first 4 h. In addition, all the samples exhibit the outstanding CO adsorption capacity of 2.83-3.96 mmol g at 273 K and 1.05 bar. Furthermore, NT-POP@800-1-6 show good selectivity ratios of 21.2-36.9 and 3.3-7.5 for CO/N or CH/N, respectively. We believe that our new building block design provides a general strategy for the construction of triazine-containing carbon materials from various extended building blocks, thereby greatly expanding the range of applicable molecules.
一系列新型含三嗪的可调节孔碳材料（NT-POP@800-1-6），通过无模板的多孔有机聚合物（POP）热解合成。NT-POP@800-1-6 具有适中的 BET 比表面积（475-736 m2/g），具有永久孔隙度和骨架中丰富的氮单元作为有效的吸附位，在最初的 4 小时内，在碘蒸气中显示出相对较快的 56-192wt%的客体吸收。此外，所有样品在 273 K 和 1.05 巴下均表现出出色的 CO 吸附能力，为 2.83-3.96mmol/g。此外，NT-POP@800-1-6 对 CO/N 或 CH/N 的选择性比分别为 21.2-36.9 和 3.3-7.5。我们相信，我们的新砌块设计为从各种扩展砌块构建含三嗪的碳材料提供了一种通用策略，从而大大扩展了适用分子的范围。
