Here, we report a novel synthetic methodology for covalent organic frameworks (COFs) that utilizes an electrogenerated acid (EGA), which is produced at an electrode surface by electrochemical oxidation of a precursor, acting as an effective Brønsted acid catalyst for imine bond formation from amine and aldehyde monomers. Simultaneously, it provides the corresponding COF film deposited on the electrode surface with high crystallinity and porosity.

使用电生酸在电极上选择性合成亚胺基共价有机框架并同时固定

在这里，我们报告了一种共价有机框架（COF）的新颖合成方法，该方法利用电生酸（EGA），该酸是通过前体的电化学氧化在电极表面产生的，作为有效的布朗斯台德酸催化剂，用于形成亚胺键胺和醛单体。同时，它提供了沉积在电极表面的相应COF薄膜，具有高结晶度和孔隙率。
