The bottom-up synthesis of highly complex functional materials from simple modular blocks is an intriguing area of research. Driven by the chemistry of supramolecular assembly, modules which self-assemble into intricate structures have been described. These hierarchically assembled systems extend beyond the individual molecule and rely on non-covalent interactions in a directed self-assembly process. The intrinsic properties of the materials can be modified by exploiting the dynamic and specific uni-directional interactions among the building. This also allows the building of novel supramolecular structures such as hydrogels, micelles and vesicles. These aqueous supramolecular networks belong to a novel category of soft biomaterials exhibiting attractive properties such as stimuli-responsiveness and self-healing properties derived from their dynamic behavior. These are important for a wide variety of emerging applications. In this review, the latest literature describing the formation of dynamic polymeric networks through host-guest complex formation will be summarised. These approaches carried out in the aqueous medium have unlocked a versatile toolbox for the design and fine-tuning of supramolecular self-assembled materials.
