Macrocycle polymeric networks based on a chair-like calix4pyrrole for the rapid and efficient adsorption of iodine from water

Two macrocycle polymeric networks (MPNs), C4P-TEPM and C4P-HEPM, were synthesized and found to exhibit iodine uptake capacities of 4.02 and 4.45 g g −1 from a KI/I 2 solution, respectively. These values are among the highest reported for iodine adsorbent materials.
