One of the challenges in water remediation is adsorbent designing, aiming at low cost and ultrafast contaminant adsorption. Herein, we developed a simple and scalable one-pot synthesis method to achieve a cost-effective anionic hypercrosslinked polymer (AHCP-1) through the Friedel–Crafts reaction with sodium tetraphenylboron as the monomer. To the best of our knowledge, this is the first anionic hypercrosslinked polymer synthesized using the Friedel–Crafts reaction. Notably, AHCP-1 possessed a high specific surface area of 939 m² g⁻¹ with a micro-/mesoporous structure. Owing to the high surface area, the abundant phenyl groups and the built-in ionic charges, AHCP-1 displayed ultrafast adsorption towards dyes and phenolic derivatives, and a high adsorption capacity of 229.89 mg g⁻¹ for RhB and 540.5 mg g⁻¹ for BPA. It is also found that the adsorption behavior is dependent on the pollutant concentration, the pH value, and the structure and charge states of the pollutant molecules.

一锅合成高度多孔的阴离子超交联聚合物，可超快吸附有机污染物†

水修复中的挑战之一是吸附剂设计，其目标是低成本和超快速的污染物吸附。在本文中，我们开发了一种简单且可扩展的一锅法合成方法，该方法通过以四苯基硼酸钠为单体的Friedel-Crafts反应实现了具有成本效益的阴离子超交联聚合物（AHCP-1）。据我们所知，这是使用Friedel-Crafts反应合成的首个阴离子超交联聚合物。值得注意的是，AHCP-1具有939 m ² g ^-1的高比表面积，具有微/中孔结构。由于高表面积，丰富的苯基和内置的离子电荷AHCP-1显示超快吸附朝向染料和酚类衍生物，以及229.89毫克g的高吸附容量^-1为罗丹明B和540.5毫克克^-1为BPA。还发现吸附行为取决于污染物浓度，pH值以及污染物分子的结构和电荷状态。
