This project focuses on the development of highly porous ╬▓-cyclodextrin polymers cross-linked with rigid aromatic groups, creating mesoporous networks capable of rapidly sequestering organic micropollutants from water. Our materials demonstrate superior adsorption rates compared to conventional activated carbon, with regeneration capabilities exceeding 200 cycles. The research addresses the critical global challenge of removing per- and polyfluoroalkyl substances (PFAS) and pharmaceutical residues from municipal water systems.
