ABSTRACT With the extensive use of nuclear energy, the disposal of radioactive iodine waste has become an issue in the energy industry. Herein, we reported a series of quadruple hydrogen‐bonded supramolecular polymers combining 2‐ureido‐41 H ‐pyrimidinone (UPy) with Tröger's base (TB) for iodine adsorption: TB‐UPys, demonstrated a volatile iodine adsorption capacity of 4 g·g −1 , with a second‐order kinetic rate constant of 2.8 × 10 −4 g·min −1 ·mg −1 for aqueous iodine adsorption. This work leverages the unique hydrogen bonding properties to construct stable and robust iodine adsorption materials, paving a new way forward for the future development of iodine adsorbents.
