Rigid H-shaped pentiptycene units, with an intrinsic hierarchical structure, were employed to fabricate a highly microporous organic polymer sorbent via Friedel-Crafts reaction/polymerization. The obtained microporous polymer exhibits good thermal stability, a high Brunauer-Emmett-Teller surface area of 1604 m g, outstanding CO, H, and CH storage capacities, as well as good adsorption selectivities for the separation of CO/N and CO/CH gas pairs. The CO uptake values reached as high as 5.00 mmol g (1.0 bar and 273 K), which, along with high adsorption selectivity values (e.g., 47.1 for CO/N), make the pentiptycene-based microporous organic polymer (PMOP) a promising sorbent material for carbon capture from flue gas and natural gas purification. Moreover, the PMOP material displayed superior absorption capacities for organic solvents and dyes. For example, the maximum adsorption capacities for methylene blue and Congo red were 394 and 932 mg g, respectively, promoting the potential of the PMOP as an excellent sorbent for environmental remediation and water treatment.
刚性 H 型五并苯单元具有内在的分级结构，通过傅克反应/聚合被用于制造一种具有高微孔有机聚合物吸附剂。所得到的微孔聚合物表现出良好的热稳定性，高的 Brunauer-Emmett-Teller 比表面积为 1604 m²/g，对 CO、H 和 CH 的存储能力优异，以及对 CO/N 和 CO/CH 气体对的分离具有良好的吸附选择性。CO 的吸附值高达 5.00 mmol g（1.0 巴和 273 K），这与高吸附选择性值（例如，CO/N 为 47.1）相结合，使得基于五并苯的微孔有机聚合物（PMOP）成为从烟道气中捕集碳和净化天然气的有前途的吸附材料。此外，PMOP 材料对有机溶剂和染料显示出优异的吸收能力。例如，亚甲蓝和刚果红的最大吸附容量分别为 394 和 932 mg/g，这促进了 PMOP 作为环境修复和水处理的优秀吸附剂的潜力。
