This book is the first to give an exhaustive overview of the structures, properties, current and possible future applications of diamondoids. The first part introduces the structures of diamondoids and gives an overview of their principal chemical and physical properties and a brief historical account, from the discovery of the first diamondoid member to the isolation of higher diamondiods. Then, current synthesis approaches and challenges in obtaining diamondoids in higher quantities are shown. Finally, approaches to generating plasmas in high-pressure and supercritical media are described.
