The fundamentally important phenomenon of mixed valency has been discussed in detail over the past 50 years, predominantly in the context of dinuclear complexes, which are used as model systems for understanding electron delocalization in more complex biological and physical systems. Very recently, mixed valency has been shown to be an important mechanism for charge transfer, leading to delocalization and conductivity in two- and three-dimensional framework materials such as metal–organic frameworks and related systems including covalent organic frameworks and semicrystalline semiconducting metal–organic graphenes. This Viewpoint provides a current perspective on the field of mixed-valence frameworks, where the property is either intrinsic or generated postsynthetically via an external stimulus. Aspects of the spectroscopy and applications of these materials are also discussed, highlighting the future potential for exploiting mixed valency in extended solid-state systems.

混合化合价作为在半导体和导电框架材料中实现电荷离域化的策略

在过去的50年中，主要在双核络合物的背景下详细讨论了混合价的根本重要现象，该双核络合物被用作模型系统，用于理解更复杂的生物和物理系统中的电子离域。最近，混合化合价已被证明是电荷转移的重要机制，导致二维和三维框架材料（例如金属有机框架和相关系统，包括共价有机框架和半结晶半导体金属有机材料）的离域和电导率石墨烯。该观点提供了混合价框架领域的最新观点，在该框架中，该属性是内在的或通过外部刺激在后期合成的。
