Supramolecular organic frameworks (SOFs) are a class of three-dimensional, potentially porous materials obtained by the self-assembly of organic building blocks held together by weak interactions such as hydrogen bonds, halogen bonds, π⋅⋅⋅π stacking and dispersion forces. SOFs are being extensively studied for their potential applications in gas storage and separation, catalysis, guest encapsulation and sensing. The supramolecular forces that guide their self-assembly endow them with an attractive combination of crystallinity and flexibility, providing intelligent dynamic materials that can respond to external stimuli in a reversible way. The present review article will focus on SOFs showing dynamic behaviour when exposed to different stimuli, highlighting fundamental aspects such as the combination of tectons and supramolecular interactions involved in the framework formation, structure-property relationship and their potential applications.
超分子有机框架（SOFs）是一类三维的、具有潜在多孔性的材料，它由有机结构单元通过氢键、卤键、π⋅⋅⋅π堆积和色散力等弱相互作用自组装而成。由于其在气体储存与分离、催化、客体封装和传感等方面的潜在应用，SOFs正受到广泛研究。引导其自组装的超分子作用力赋予了它们结晶性和柔韧性这一吸引人的组合特性，从而提供了能够以可逆方式响应外部刺激的智能动态材料。本综述文章将聚焦于在受到不同刺激时表现出动态行为的SOFs，突出诸如框架形成过程中涉及的构造单元与超分子相互作用的组合、结构-性能关系及其潜在应用等基本方面。
