Constructing cationic covalent organic frameworks by a post-function process for an exceptional iodine capture <i>via</i> electrostatic interactions

Abstract

Cationic covalent organic frameworks are obtained <italic>via</italic> post-functionalization and compared to the neutral COFs, the I₂ uptake capacities are improved by 1.3 times due to the electrostatic interactions between COFs’ networks and I₂ molecules.
