摘要：

Proton transport across wide temperature ranges is critical for applications in energy conversion and life sciences. Covalent organic frameworks (COFs), with their ordered nanopores, provide an ideal platform for proton conduction. Here, fluorination strategies are employed to modify COF pore interfaces, leveraging fluorine's hydrogen-bond induction effect to enhance water mass transfer. Fluorinated COFs membrane exhibits stable proton conductivity from -40 degrees C to 80 degrees C, attributed to disrupted water clusters and a dynamic metastable phase. This work demonstrates the potential of fluorinated COFs as advanced proton-conducting materials.
