Sulfur is a massive byproduct of the petrochemicals industry and hardly employed as a building block for porous organic polymers (POPs). Here, a new family of sulfur-bridged POPs has been prepared via a C–H insertion reaction between sulfur and polycyclic aromatic hydrocarbons. Sulfur works as a solvent, external cross-linker, and porogen simultaneously during the polymerization process. The products demonstrate high porosity and maximum surface area of 1050 m² g^–1 with abundant accessible active sites, contributing to the nanometerization of sulfur and significantly enhancing the inherent affinity between heteroatoms toward soft metal ions. Therefore, they exhibit a high absorption capacity for Au(III) of 3287 mg g^–1 and excellent absorption selectivity and removal efficiency via a performance evaluation even in real electronic wastewater. This synthetic strategy to prepare high added-value functional POPs with sulfur not only sheds light on designing high-performance gold adsorption materials and emerging POPs, but also promotes a sustainable development protocol.

三鸟一硫：构建硫桥多孔有机聚合物以实现高效金吸附


硫是石化工业的大量副产品，几乎不用作多孔有机聚合物 (POP) 的原料。在这里，通过硫和多环芳烃之间的 C-H 插入反应制备了一个新的硫桥 POP 家族。硫在聚合过程中同时充当溶剂、外部交联剂和致孔剂。该产品具有高孔隙率和 1050 m ² g ^–1 的最大表面积，具有丰富的活性位点，有助于硫的纳米化并显着增强杂原子与软金属之间的固有亲和力离子。因此，即使在真实的电子废水中，通过性能评估，它们也表现出对 Au(III) 3287 mg g ^–1 的高吸收能力，以及优异的吸收选择性和去除效率。这种用硫制备高附加值功能性持久性有机污染物的合成策略不仅为高性能金吸附材料和新兴持久性有机污染物的设计提供了思路，而且还促进了可持续发展协议。
