Smart materials constructed through supramolecular assemblies have been receiving considerable attention because of their potential applications, which include self-healing materials, energy storage, photonic devices, sensors and theranostics. Host–guest chemistry of various macrocyclic receptors with organic guests provides a unique way to control tailor-made nanoarchitectures for the formation of pre-designed functional materials. Cucurbituril-based Function Materials provides an overview of this fascinating macrocycle, cucurbituril (CB) homologues and derivatives-based supramolecular nanostructured materials. Chapters cover the synthesis, properties and application of CB-based smart materials and nanostructures. With contributions from key researchers, this book will be of interest to students and researchers working in materials science, as well as those working on cucurbituril-based materials in organic and physical chemistry.
