Stimuli-responsive materials can respond to external effects, and proton transport is widespread and plays a key role in living systems, making stimuli-responsive proton transport in artificial materials of particular interest to researchers due to its desirable application prospects. On the basis of the rapid growth of proton-conducting porous metal-organic frameworks (MOFs), switched proton-conducting MOFs have also begun to attract attention. MOFs have advantages in crystallinity, porosity, functionalization, and structural designability, and they can facilitate the fabrication of novel switchable proton conductors and promote an understanding of the comprehensive mechanisms. In this Perspective, we highlight the current progress in the rational design and fabrication of stimuli-responsive proton-conducting MOFs and their applications. The dynamic structural change of proton transfer pathways and the role of trigger molecules are discussed to elucidate the stimuli-responsive mechanisms. Subsequently, we also discuss the challenges and propose new research opportunities for further development.
刺激响应材料能够对外界作用做出响应，质子传输广泛存在且在生命系统中起着关键作用，这使得人工材料中的刺激响应质子传输因其良好的应用前景而备受研究人员关注。基于质子传导多孔金属有机框架（MOF）的快速发展，可切换质子传导MOF也开始受到关注。MOF在结晶度、孔隙率、功能化和结构可设计性方面具有优势，它们有助于制备新型可切换质子导体并促进对综合机制的理解。在这篇综述中，我们重点介绍了刺激响应质子传导MOF的合理设计与制备及其应用方面的当前进展。讨论了质子转移途径的动态结构变化和触发分子的作用，以阐明刺激响应机制。随后，我们还讨论了挑战并提出了进一步发展的新研究机会。
