Host–guest molecular recognition at the liquid–liquid interface endows the interface with unique properties, including stimuli-responsiveness and self-regulation, due to the dynamic and reversible nature of non-covalent interactions. Increasing research efforts have been put into the preparation of supramolecular interfacial systems such as films and microcapsules by integrating functional components (e.g., colloidal particles, polymers) at the interface, providing tremendous opportunities in the areas of encapsulation, delivery vehicles, and biphasic reaction systems. In this review, we summarize recent progress in supramolecular interfacial systems assembled by host–guest chemistry, and provide an overview of the fabrication process, functions, and promising applications of the resultant constructs.

由于非共价相互作用的动态和可逆性质，液-液界面上的主客体分子识别赋予了界面独特的性质，包括刺激响应性和自我调节。越来越多的研究努力通过在界面处整合功能组分（如胶体颗粒、聚合物）来制备薄膜和微胶囊等超分子界面系统，为封装、运载工具和双相反应系统领域提供了巨大的机会. 在这篇综述中，我们总结了由主客体化学组装的超分子界面系统的最新进展，并概述了由此产生的结构的制造过程、功能和有前景的应用。
