Porous pillar[6]arene-based polymers for reversible iodine capture.

ABSTRACT: Iodine in nuclear waste can cause serious environment pollution and health risks, and has thus driven more development of materials for iodine capture. Herein, a novel porous pillar[6]arene-based polymer (P-P6APs) was easily prepared as a supramolecular adsorbent for iodine via a one-step crosslinking reaction between per-hydroxylated pillar[6]arene and decafluorobiphenyl. Nitrogen adsorption tests demonstrated that this material possessed a satisfactory surface area (S _BET = 366 m² g^-1) and pore diameter (3.8 nm), which was due to the macrocyclic scaffolds. Compared with commercially available activated carbon, P-P6APs exhibited superior adsorption efficiency toward volatile iodine not only in the solution phase (water and n-hexane) bu
