The existence of correlated disorder in molecular frameworks is an obvious mechanism by which unusual cooperative phenomena might be realised. We show that the use of local-symmetry lowering approaches can allow ostensibly high-symmetry framework structures to harbour exotic disordered states often studied in the context of spin lattice models. These states exhibit strongly cooperative behaviour that might be exploited in anomalous mechanical, host/guest, and information storage behaviour. Our contribution focuses in particular on the concepts of (i) combinatorial mechanics, (ii) adaptive flexibility, and (iii) error-correcting data storage in framework materials.
分子框架中相关无序现象的存在是一种明显的机制，通过该机制可能实现异常的协同现象。我们表明，使用降低局部对称性的方法可以使表面上具有高对称性的框架结构容纳通常在自旋晶格模型背景下研究的奇异无序状态。这些状态表现出强烈的协同行为，可用于异常的机械、主/客体和信息存储行为。我们的贡献尤其集中在以下概念上：（i）组合力学，（ii）自适应灵活性，以及（iii）框架材料中的纠错数据存储。
