Le résumé fourni par la source
Imine-based covalent organic frameworks (COFs) are crystalline porous materials with prospective uses in various devices.However, general bulk synthetic methods usually produce COFs as powders that are insoluble in most of the common organic solvents, arising challenges for the subsequent molding and fixing of these materials on substrates.Here, we report a novel synthetic methodology that utilizes an electrogenerated acid (EGA), which is produced at an electrode surface by electrochemical oxidation of a suitable precursor, acting as an effective Brønsted acid catalyst for imine bond formation from the corresponding amine and aldehyde monomers.Simultaneously, it provides the corresponding COF film deposited on the electrode surface.The COF structures obtained with this method exhibited high crystallinities and porosities, and the film thickness could be controlled.Furthermore, such process was applied for the synthesis of various imine-based COFs, including a three-dimensional (3D) COF structure.
