Adaptable crystalline frameworks are important in modern solid-state chemistry as they are able to accommodate a wide range of elements, oxidation states, and stoichiometries. Owing to this ability, such adaptable framework structures are emerging as the prototypes for technologically important advanced functional materials. In this Account, the idea of cosubstitution is explored as a useful “pairing” concept that can potentially lead to the creation of many new members of one particular framework structure. Cosubstitution as practiced is the simultaneous replacement of two or more cations, anions, complex anions, other fundamental building units, or vacancies. Although the overall sum of the oxidation states is constant, each component is not necessarily isovalent. This methodology is typically inspired by either mineral-type structural prototypes found in nature or those discovered in the laboratory. Either path leads to the appearance of new phases and the discovery of new materials. In addition, the chemical cosubstitution approach can be successfully adopted to improve physical properties associated with structures.

化学启发的适应性框架结构

适应性强的晶体构架在现代固态化学中非常重要，因为它们能够适应各种元素，氧化态和化学计量比。由于这种能力，这种适应性强的框架结构正成为具有技术重要性的高级功能材料的原型。在此帐户中，共替代的概念是一种有用的“配对”概念，可以潜在地导致创建一个特定框架结构的许多新成员。共同替代是同时替换两个或多个阳离子，阴离子，复杂阴离子，其他基本结构单元或空位。尽管氧化态的总和是恒定的，但是每个组分不一定是等价的。这种方法通常受自然界中发现的矿物类型结构原型或实验室中发现的矿物原型结构原型的启发。任一种方法都会导致出现新的阶段并发现新的材料。另外，化学共取代方法可以成功地用于改善与结构相关的物理性质。
