The discharge of organic pollutants poses a serious threat to public health and the environment. Developing new strategies and materials to remove organic pollutants from water efficiently and completely is of great importance. Herein, a SnS 2 ‐modified porous β‐cyclodextrin‐containing polymer (SnS 2 @PCDP), which was derived by nucleophilic aromatic substitution of the hydroxyl groups of both β‐CD and SnS 2 −OH by tetrafluoroterephthalonitrile, was prepared for the rapid, complete removal of organic pollutants from water . The porous structure and well‐defined cavities of β‐CD endow SnS 2 @PCDP with a facile and high adsorption capacity, and the modification with SnS 2 leads to simultaneous adsorption and photodegradation processes for the rapid and complete removal of organic pollutants. In addition, SnS 2 @PCDP can be regenerated several times using light irradiation with no loss in performance. Overall, the efficient removal performance and excellent reusability indicate that SnS 2 @PCDP has potential for practical applications in the efficient treatment of organic pollutants.
