Abstract:
Covalent organic frameworks (COFs) are an up-and-coming class of porous functional materials featuring well-defined crystalline structures, high porosity, and large surface areas. Proton-conductive COFs have recently elicited extensive attention due to their promising applications in fuel cells, supercapacitors, and sensors. This review systematically covers the latest five-year progress of proton-conductive COFs, categorized by connection bond types (CN, CN, CC, CO) and conduction environments (hydrous and anhydrous). It focuses on their synthesis methods, proton conduction mechanisms, and applications. By highlighting the significant achievements and current challenges in this field, this review intends to provide insights for future research directions and the development of more efficient proton-conducting COF materials.

Covalent Bonds
When two atoms share electrons to complete their valence shells, they create a covalent bond. An atom's electronegativity—the force with which shared electrons are pulled towards an atom—determines how the electrons are shared. Molecules formed with covalent bonds can be either polar or nonpolar. Atoms with similar electronegativities form nonpolar covalent bonds; the electrons are shared equally. Atoms with different electronegativities share electrons unequally,...
