Organic micropollutant in the aquatic environment has become a worldwide problem. In this study, a new DMpillar[5]arene-based porous organic polymer (DMPBP[5]) with the highest surface area of 1347.4 ± 39.3 m² g⁻¹ is developed through Friedel-Crafts alkylation reaction between DMpillar[5]arene (DMP5) and 4,4′-bis(chloromethyl)-1,1′-biphenyl (BCMBP) to remove a wide range of organic micropollutants with fast removal rate and large uptake amounts. The synthesized DMPBP[5] can capture many types of organic pollutants in water including positively charged, negatively charged and neutral ones and those with different hydrophilicity, through host–guest interaction, hydrophobic interaction, electrostatic interaction and π-π interaction. For some pollutants, the adsorption kinetic constants of DMPBP[5] are thousands of times larger than that of activated carbon (AC) and even 10⁴-10⁵ times larger than that of resin (XAD-4), and the adsorption capacities of DMPBP[5] are about 3 and 4 times higher than that of AC and XAD-4, respectively. The superior adsorption performance of DMPBP[5] is attributed to permanent porosity and accessible binding sites because of the introduction of rigid structure. Even at environmentally relevant concentrations, DMPBP[5] can quickly remove the pollutants simultaneously and can be easily regenerated with methanol under ambient conditions. In short, due to the wide adsorption range, excellent adsorption performance, and easy recyclability, DMPBP[5] is an excellent adsorbent for wastewater treatment with great application potential.

水环境中的有机微污染物已成为世界性难题。在这项研究中，一种新的 DMpillar[5]芳烃基多孔有机聚合物（DMPBP[5]）的最高表面积为 1347.4 ± 39.3 m ² g ^-1通过 DMpillar[5]芳烃 (DMP5) 与 4,4'-双(氯甲基)-1,1'-联苯 (BCMBP) 之间的傅克烷基化反应开发，可快速去除多种有机微污染物，并摄取量大。合成的DMPBP[5]可以通过主客体相互作用、疏水相互作用、静电相互作用和π-π相互作用捕获水中多种类型的有机污染物，包括带正电、带负电和中性以及具有不同亲水性的有机污染物。对于某些污染物，DMPBP[5]的吸附动力学常数是活性炭（AC）的数千倍，甚至10 ⁴ -10 ⁵比树脂 (XAD-4) 大 1 倍，DMPBP[5] 的吸附能力分别是 AC 和 XAD-4 的 3 倍和 4 倍。由于引入了刚性结构，DMPBP[5] 的优异吸附性能归因于永久性孔隙率和可接近的结合位点。即使在与环境相关的浓度下，DMPBP[5] 也可以同时快速去除污染物，并且可以在环境条件下用甲醇轻松再生。总之，由于吸附范围广、吸附性能优良、易于回收利用，DMPBP[5]是一种具有很大应用潜力的废水处理的优良吸附剂。
