Hybrid Supramolecular Assemblies of Cucurbit[n]uril-supported Metal and Other Inorganic Nanoparticles

Nanoparticles (NPs) have promising applications in catalysis, sensing, theranostics, plasmonics and other areas. Since bare NPs undergo spontaneous agglomeration, which diminishes their activity, they need to be stabilized by suitable capping agents to maintain their dispersion in water. Capping agents that bind with NPs involving reasonably mild interactions are preferred because they allow target molecules to access NP surfaces quite easily, resulting in the most desired effects. Cucurbit[n]uril (CB[n]) macrocycles have been identified as soft capping agents, as they bind to NP surfaces using simple noncovalent interactions involving their polarizable carbonyl portals. Moreover, CB[n] hosts help in bringing out additional functionalities of the NPs. Extensive studies have been reported on various CB[n]-assisted NP systems, exploring their potential in diverse applications. In this chapter, our effort has been to summarize some of the important results reported in the literature, discussing mainly CB[n]-assisted metal nanoparticles and some inorganic nanomaterial systems.
