Two new imine-linked covalent organic frameworks flexible units for high iodine uptake

Two new imine-linked covalent organic frameworks (NI-COF-1 and NI-COF-2) have been designed and constructed through a Schiff base condensation reaction. NI-COFs displayed good porosity, stability, and crystallinity via flexible units modified by fluorine atoms. These advantages gave the uniform chan...

Summary:Two new imine-linked covalent organic frameworks (NI-COF-1 and NI-COF-2) have been designed and constructed through a Schiff base condensation reaction. NI-COFs displayed good porosity, stability, and crystallinity via flexible units modified by fluorine atoms. These advantages gave the uniform channel elasticity and adaptability to capture guest molecules. Surprisingly, the iodine capture ability of NI-COFs can reach as high as 4.92 g g −1 . Two imine-linked covalent organic frameworks displayed good porosity, stability, and crystallinity via the flexible units, suggesting high iodine capture ability.
