Abstract
Abstract Adsorbents widely utilized for environmental remediation, water purification, and gas storage have been usually reported to be either porous or crystalline materials. In this contribution, we report the synthesis of two covalent organic superphane cages, that are utilized as the nonporous amorphous superadsorbents for aqueous iodine adsorption with the record–breaking iodine adsorption capability and selectivity. In the static adsorption system, the cages exhibit iodine uptake capacity of up to 8.41 g g −1 in I 2 aqueous solution and 9.01 g g −1 in I 3 − (KI/I 2 ) aqueous solution, respectively, even in the presence of a large excess of competing anions. In the dynamic flow-through experiment, the…
