Biomorphic supramolecular assemblies formed through the collaboration of rigidity and flexibility, akin to bones and ligaments, play a crucial role in constructing advanced functional structures. Non-intertwined ring-ring assemblies that rely on induced fitting between rigid rings and conformationally flexible rings, have emerged as one of the thriving representatives. However, detailing how rigid and flexible rings adapt to each other for precise self-assembly evolution under solely weak non-covalent interactions remains limited and often poses challenges in structural design. We offer a distinctive solution by distorting the rigid cyclophane, thereby providing not only unique dual recognition sites for flexible guests but also intrinsic solid-state emission for in-situ visualization of dynamic processes. Three adaptive self-assemblies ranging from ring-within-ring, to ring-bridge-ring and finally to ring-in-ring were constructed and demonstrated to be dynamic responsive in solid state through harnessing the high selectivity of the inner rings.

刚性环和柔性环的自适应动态非缠绕装配

通过刚性和柔性的协作形成的生物形态超分子组装体，类似于骨骼和韧带，在构建先进的功能结构中发挥着至关重要的作用。非缠绕环-环组件依赖于刚性环和构象柔性环之间的诱导配合，已成为蓬勃发展的代表之一。然而，详细说明刚性环和柔性环如何在仅弱非共价相互作用下相互适应以实现精确的自组装进化仍然有限，并且常常给结构设计带来挑战。我们通过扭曲刚性环芳烷提供了独特的解决方案，从而不仅为灵活的客人提供了独特的双重识别位点，而且还为动态过程的原位可视化提供了内在的固态发射。构建了三种自适应自组件，从环中环，到环桥环，最后到环中环，并通过利用内环的高选择性，证明其在固态下具有动态响应能力。
