One-dimensional fluorescent covalent organic frameworks rich in exposed sp³-N sites for ultra-fast iodine capture and visual monitoring.

ABSTRACT: It is important to capture radioactive iodine, especially highly volatile CH₃I and I₂, from nuclear waste for pollution control. Research has indicated the great potential that covalent organic frameworks possess for iodine capture, and several covalent organic frameworks (COFs) with high adsorption capacities have been reported. However, increasing the capture rate of gaseous iodine remains a major challenge at present. To this end, researchers have improved iodine capture rates by introducing macropores, nitrogen sites, and heteroatoms. In the field of catalysis, 1D COFs have been used due to their abundant exposed sites. Inspired by this, we postulated that it is feasible to increase the exposure of N sites to increase the iodine capture rate. Herein, we report a s
