Pillararene polymers have been widely used as excellent adsorbents for water treatment, but pillararene polymers with ultra-high specific surface area and versatility are still rarely reported. Herein, a quaternary ammonium salt modified pillar [5] arene polymer, QPBP [5], with specific surface area of 1844 m² g⁻¹ was successfully synthesized. Since QPBP [5] has abundant different adsorption sites, it exhibits excellent performance for the simultaneously removal of organic pollutants with different charges from water. The selected three model pollutants, Rhodamine B (RhB, positively charged), Sulfamethazine (SMT, electrically neutral) and Fulvic acid (FA, negatively charged), could be rapidly and efficiently removed from water by QPBP [5] within 10 min, which are much faster than them by most of the reported adsorbents. RhB and SMT are mainly adsorbed through hydrophobic interactions with the QPBP [5] surface, while FA is mainly removed through ion exchange. In addition, QPBP [5] also showed excellent reusability and adsorption performance for the environmentally relevant concentration of pollutants. Furthermore, the quaternary ammonium groups on QPBP [5] makes it a solid disinfectant with excellent antibacterial properties. In conclusion, QPBP [5] is a promising multifunctional adsorbent for the treatment of complex pollutants in water.

柱芳烃聚合物作为优异的水处理吸附剂已被广泛应用，但具有超高比表面积和多功能性的柱芳烃聚合物仍鲜有报道。在此，成功合成了季铵盐改性的柱[5]芳烃聚合物QPBP [5]，其比表面积为1844 m ²  g ^{-1 。}由于QPBP[5]具有丰富的不同吸附位点，因此在同时去除水中不同电荷的有机污染物方面表现出优异的性能。所选的三种模型污染物，罗丹明B（RhB，带正电）、磺胺二甲嗪（SMT，电中性）和黄腐酸（FA，带负电），可以通过 QPBP [5] 在 10 分钟内快速有效地从水中去除，这大多数报道的吸附剂都比它们快得多。RhB和SMT主要通过与QPBP[5]表面的疏水相互作用被吸附，而FA主要通过离子交换被去除。此外，QPBP[5]还表现出优异的可重复使用性和对环境相关浓度污染物的吸附性能。此外，QPBP上的季铵基团[5]使其成为具有优异抗菌性能的固体消毒剂。总之，QPBP [5]是一种有前途的多功能吸附剂，用于处理水中的复杂污染物。
