“…Lee and Park tested the iodine adsorption behavior of two different types of isostructural organic frameworks, UiO-66-X series (X=H, Br, NO 2 , NH 2 , (OH) 2 , and (COOH) 2 ) and M 2 (m-DOBDC) series. [92] Among all groups, the carboxylic acid group (À COOH) exhibits the fastest adsorption kinetics and highest adsorption capacity. Recently, a series of Th-UiO-66 MOFs were modified with different functional groups (NH 2 , (NH 2 ) 2 , OH, CH 3 , OCH 3 , (OCH 3 ) 2 , NO 2 , Cl, Br, Cl 2 , Br 2 and (CF 3 ) 2 ) as standard models to systematically study the effect of substituents on iodine adsorption in solution and vapor state (Figure 4a).…”
