Cover Feature: Boosting the Iodine Adsorption and Radioresistance of Th‐UiO‐66 MOFs via Aromatic Substitution (Chem. Eur. J. 4/2021)

Effective capture of radioactive iodine is of paramount importance for the safe and long-term storage of fission products in the nuclear fuel cycle. By adopting the ThIV cation with appropriate “hardness” as the building block, a series of functionalized Th-UiO-66 MOFs with high-quality single crystals were synthesized, serving as a model to investigate the effects of substituents on iodine adsorption. The electro-donating NH2 group exhibits the most positive role on boosting iodine adsorption and it can also enhance the radioresistance of the corresponding framework.
