Design and application of covalent organic frameworks for ionic conduction

Abstract

Covalent organic frameworks (COFs) are a new class of crystalline porous polymers that have received extensive attention from researchers in various backgrounds. Attributed to their highly ordered porous structures, outstanding chemical stability, large specific surface area, designable pore environment, and adjustable functionalities, COFs have shown great potential for ion conduction application. This review focuses on summarizing the state-of-the-art progress of COFs in ion conduction, especially in the fields of proton conduction, lithium-ion conduction, and anion conduction. Finally, the existing challenges in the field and the future development direction are prospected.
