WebAug 26, 2024 · The properties of a sp 2-carbon-linked covalent organic framework (COF) were dramatically improved by a gradient heating synthetic strategy. The new framework … WebJul 5, 2024 · This was achieved through the crystallization of an imine-linked COF, termed COF-609-Im, followed by conversion of its imine linkage to base-stable tetrahydroquinoline linkage through aza-Diels–Alder cycloaddition, and finally, the covalent incorporation of tris (3-aminopropyl)amine into the framework.
The most popular COF synthesis route is a boron condensation reaction which is a molecular dehydration reaction between boronic acids. In case of COF-1, three boronic acid molecules converge to form a planar six-membered B 3 O 3 ring with the elimination of three water molecules.
