Electrical bistability existing in biochemical networks is critical for the proper functionalization of living systems. The development of artificial materials with electrical bistability begun to attract much interest due to their broad application prospects, especially in the field of memristors. Metal-organic frameworks (MOFs) have advantages in regular pores, crystallinity, structural designability and easy functionalization, which can promote the construction of novel MOF-based memristors and facilitate a better understanding of switching mechanisms. Here, we highlight recent advances in electrically bistable MOFs as memristors, and discuss their switching mechanisms, including interfacial reaction, proton-transfer mechanism, metal ion migration, charge trapping/detrapping and other mechanisms. Challenges and future perspectives are also presented.
电双稳存在于生化网络中，对于生命系统的正常功能化至关重要。具有电双稳特性的人工材料由于其广阔的应用前景，特别是在忆阻器领域，开始引起人们的极大兴趣。金属有机骨架（MOFs）在规则孔、结晶度、结构可设计性和易于功能化方面具有优势，这可以促进新型基于 MOF 的忆阻器的构建，并有助于更好地理解开关机制。在这里，我们重点介绍了作为忆阻器的电双稳 MOFs 的最新进展，并讨论了它们的开关机制，包括界面反应、质子转移机制、金属离子迁移、电荷俘获/释放等机制。还提出了挑战和未来展望。
