Host–Guest Molecular Recognition at Liquid–Liquid Interfaces

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