“…With the population growth and industrial development, nuclear energy has become as one of the most promising energy sources for mankind. − However, the fission products, especially 129 I and 131 I, are radioactive and have enormous threats to human health. − Therefore, the development of effective ways to capture radioactive iodine is of great practical significance. − Various materials, including zeolites, activated carbons, aerogels, and functionalized clays, have been utilized for iodine adsorption. − Nevertheless, they usually adopt irregular pore distributions, random adsorption sites, and poor structural order, precluding the visualization of host–guest or guest–guest interactions.…”

The sustainable development of nuclear energy urgently requires the development of appropriate materials for the effective adsorption of radioiodine. Electron-donating groupfunctionalized layered metal−organic frameworks (MOFs) can not only enhance the host−guest interactions but also avoid the reduction of free pore voids benefit by the flexible interlayer spacing, supposed to have excellent I 2 adsorption ability. Herein, by rational selection of methyl-decorated aromatic 4,4′,4″-(2,4,6trimethylbenzene-1,3,5-triyl)tribenzoic acid (H 3 TMTB) and Zn-(NO 3 ) 2 •6H 2 O as the building units, a three-blade-paddlewheel unit-based layered [Zn 2 (TMTB)(H 2 O) 2 ]•(OH − )•guest (1), possessing rare [Zn 2 (COO) 3 (H 2 O) 2 ] + unit, was successfully synthesized and systematically characterized. I 2 adsorption study indicated that 1 is recyclable and the maximum adsorption in organic solution and vapor phase is 77.7 mg g −1 and 2.00 g g −1 , respectively. Grand Canonical Monte Carlo simulations revealed that the layered structure in synergy with the coexistence of −CH 3 , π-electron-rich phenyl, and [Zn 2 (COO) 3 (H 2 O) 2 ] + contribute to the excellent performance. This work may provide a new way for the development of advanced I 2 adsorption MOF-based materials.
