Recovery of environmental iodine is great significance for both recycling resources and addressing pollution. However, highly sensitive to factors exists in various chemical species, which complicates the recovery trace aqueous systems. Here a porous aromatic framework (iPAF-TEPT) presented with multifunctional adsorption sites efficient including molecular (I2), iodide (I- I3 -). The material utilizes synergistic strategy combining charge-transfer interactions Coulomb effectively adsorb different species. Thanks its high density accessible ion exchange I⁻ I3⁻, nitrogen-rich I2, iPAF-TEPT demonstrates an unprecedented capacity forms. Notably, achieves exceptional removal efficiency pollutants, even at concentrations as low 100 ppb, making it first promising single-framework treatment contamination.
