Molecular Switches

The long-awaited second edition of the successful book covering molecular switches now in two volumes! Providing principles and applications this book brings you everything you need to know about molecular switches - a hot topic in the nanoworld. The major classes of molecular switches including catenanes, rotaxanes, azobenzenes together with polymer and biomolecular switching systems and DNA based switches are covered. Chemists and material scientists interested in one of the most innovative areas of their science will benefit greatly from reading this book. "This book will appeal most to organic chemists, because of the way new structures are introduced through their synthesis, but it will also provide a useful introduction for other scientists, provided they are conversant with molecular structures." (Organic and Biomolecular Chemistry) "...a comprehensive and up-to-date insight ..." (Chemistry & Industry)
