Owing to increasing global demand for the development of multifunctional advanced materials with various practical applications, great attention has been paid to metal-organic frameworks due to their unique properties, such as structural, chemical, and functional diversity. Several strategies have been developed to promote the applicability of these materials in practical fields. The induction of mixed-valency is a promising strategy, contributing to exceptional features in these porous materials such as enhanced charge delocalization, conductivity, magnetism, The current review provides a detailed study of mixed-valence MOFs, including their fundamental properties, synthesis challenges, and characterization methods. The outstanding applicability of these materials in diverse fields such as energy storage, catalysis, sensing, gas sorption, separation, is also discussed, providing a roadmap for future design strategies to exploit mixed valency in advanced materials. Interestingly, mixed-valence MOFs have demonstrated fascinating features in practical fields compared to their homo-valence MOFs, resulting from an enhanced synergy between mixed-valence states within the framework.
由于全球对具有各种实际应用的多功能先进材料的需求不断增加，金属有机框架因其独特的性质，如结构、化学和功能多样性，而受到了极大的关注。已经开发了几种策略来促进这些材料在实际领域的适用性。引入混合价态是一种很有前景的策略，有助于这些多孔材料具有特殊的特性，如增强的电荷离域、导电性、磁性。本综述对混合价态金属有机框架进行了详细研究，包括它们的基本性质、合成挑战和表征方法。还讨论了这些材料在能量存储、催化、传感、气体吸附、分离等不同领域的出色适用性，为未来在先进材料中利用混合价态的设计策略提供了路线图。有趣的是，与同价态金属有机框架相比，混合价态金属有机框架在实际领域表现出迷人的特性，这是由于框架内混合价态之间增强的协同作用所致。
