This paper reports a strategy for constructing highly efficient perfluorooctanoic acid (PFOA) adsorbents by installing synergistic electrostatic/hydrophobic sites onto porous organic polymers (POPs). The resulting material, PAF-1-NDMB, exhibits exceptionally high PFOA uptake capacity (over 2000 mg g⁻¹), significantly exceeding that of benchmark materials. PAF-1-NDMB also demonstrates remarkably fast kinetics, removing PFOA to levels below EPA advisory levels within 2 minutes. This approach offers a generic method for creating efficient PFOA adsorbents and establishes POPs as a platform for PFOA capture.
