Abstract
The production of graphene with controlled properties and structure is one of the most challenging aspects for a chemist. Covalent functionalization is one of the common approaches to obtain well-defined and robust modification of carbon materials. Different protocols have been proposed for carrying out this functionalization step. However, aryl diazonium salts chemistry should be highlighted due to its efficiency and simplicity. In this book chapter we focus on the modification of carbon materials with sp2 hybridization (graphite and graphene) by using aryl diazonium salts. The on-surface chemistry of diazonium salts on model substrates is explored with a focus on the attempts that have been done to improve the fundamental knowledge about the aryl-carbon interface. Recent developments include control of the structure and the spatial distribution of the aryl moieties on the surface. Finally, the expansion of the protocols to bulk dispersions of graphene and the advantages for the mass production and development of applications based on this material are highlighted.
