Abstract: Self-assembly is emerging as a superior method to prepare adaptive and responsive nanomaterials. The structure and function of these materials is entirely determined by the dynamic and weak interactions of the constituent molecular “building blocks” of the material. Since the inherent interactions are weak, these versatile materials readily respond to even small changes and stimuli in their environment. Moreover, these materials are biomimetic and contain large amounts of water, so that application in biomedical technology can be foreseen.
This lecture will highlight our recent work on self-assembled supramolecular nanomaterials that respond to light. Amongst others, light responsive host-guest complexes, hydrogels, foams, nanocontainers and adhesives will be discussed.
