On account of its nonbiodegradable nature and persistence in the environment, perfluorooctanoic acid (PFOA) accumulates in water resources and poses serious environmental issues in many parts of the world. Here, we present the development of two fluorine-rich calix[4]arene-based porous polymers, and , and demonstrate their utility for the efficient removal of PFOA from water. These materials featured Brunauer-Emmett-Teller (BET) surface areas of up to 450 m g, which is slightly lower than their nonfluorinated counterparts (up to 596 m g). removes PFOA at environmentally relevant concentrations with a high rate constant of 3.80 g mg h and reached an exceptional maximum PFOA uptake capacity of 188.7 mg g. In addition, it could be regenerated by simple methanol wash and reused without a significant decrease in performance.
由于全氟辛酸（PFOA）具有不可生物降解的性质且在环境中具有持久性，它会在水资源中积累，并在世界许多地区引发严重的环境问题。在此，我们展示了两种基于富含氟的杯[4]芳烃的多孔聚合物的开发，并证明了它们在从水中有效去除PFOA方面的效用。这些材料的布鲁诺尔-埃米特-特勒（BET）表面积高达450 m²/g，略低于其非氟化对应物（高达596 m²/g）。[具体聚合物名称]以3.80 g mg⁻¹ h⁻¹的高速率常数在环境相关浓度下去除PFOA，并达到了188.7 mg g⁻¹的异常最大PFOA吸附容量。此外，它可以通过简单的甲醇洗涤再生并重复使用，而性能不会显著下降。
