•Proton conductive covalent organic frameworks were reviewed.•COFs are classified and described according to the type of linkages.•Proton conductivity and conducting mechanism were discussed.•The future development trend of such COFs is prospected.
As a new class of promising crystalline solid materials, the preparation and application of covalent organic frameworks (COFs) have aroused great interest in recent years. In this review, we will focus on the recent research achievements of COFs in the field of proton conductivity from the aspects of design strategies, structural characteristics, proton conducting features and mechanism, application research, etc. Finally, we will present a forward-looking view on the future development and challenges of such functional materials as well as preparation techniques and strategies.
