Regulating the iodine adsorption performances of two- and three-component β-ketoenamine-linked covalent organic frameworks through tuning the proportion of monomers

The crystallinity, specific surface area, and amino content of NH 2 -Th X -Mth 1− X -Tfp COFs have been effectively regulated by changing the mole ratio of NH 2 -Th and Mth. Interestingly, they showed different iodine vapour capture performances.
