Book excerpt: Hyper-structured molecules are topologically well-defined molecules in two or three dimensions and are expected to show novel quantum effects in the molecules themselves or in molecular sequences. This book, covering the supramolecular chemistry and characterisation of hyper-structured molecules, provides an invaluable resource on the design and synthesis of topologically controlled molecules such as dendritic polymers, and on ways to handle them using techniques such as photon scanning tunnelling microscopy. The book presents a comprehensive discussion of the real application of hyper-structured molecules to organic quantum devices for molecular electronics, photonics and spinics and should be of interest to all researchers working in supramolecular chemistry and molecular electronics.
