Covalent organic frameworks (COFs) are of interest for energy storage devices, such as electrochemical supercapacitors, because of their micro- or meso-porosity, high surface areas, and predictable organization of redox-active groups. However, the poor hydrolytic and oxidative instability of established COF linkages, such as boroxines and boronate esters, represent a major stumbling block towards using COFs for these applications. Recently developed �-ketoenamine-linked COFs are stable to water and acid, making them ideal linkages for electrochemical applications. The synthesis, characterization, and electrochemical performance of a redox-active �-ketoenamine-linked COF, which is the first such material to exhibit a reversible electrochemical response, will be presented.
