Solid-state proton-conductive materials have been of great interest for several decades due to their promising application as electrolytes in fuel cells and electrochemical devices. Metal-organic materials (MOMs) have recently been intensively investigated as a new type of proton-conductive materials. The highly crystalline nature and structural designability of MOMs make them advantageous over conventional noncrystalline proton-conductive materials-the detailed investigation of the structure-property relationship is feasible on MOM-based proton conductors. This review aims to summarize and examine the fundamental principles and various design strategies on proton-conductive MOMs, and shed light on the nanoconfinement effects as well as the importance of hydrophobicity on specific occasions, which have been often disregarded. Besides, challenges and future prospects on this field are presented.
几十年来，固态质子导电材料因其在燃料电池和电化学装置中作为电解质的应用前景而备受关注。金属有机材料（MOMs）最近作为一种新型质子导电材料受到了深入研究。MOMs的高结晶性和结构可设计性使其优于传统的非晶质子导电材料——基于MOM的质子导体对结构-性能关系进行详细研究是可行的。本综述旨在总结和研究质子导电MOMs的基本原理和各种设计策略，并阐明纳米限域效应以及特定情况下疏水性的重要性，而这些往往被忽视。此外，还介绍了该领域的挑战和未来前景。
