The knowledge of the element carbon has inflationary been expanded with the advent of the fullerenes, carbon nanotubes and graphene. These modifications of carbon exhibit a broad portfolio of unprecedented physical properties rendering them ideal candidates for future high-performance components in electrical and mechanical devices. All three molecular allotropes share one common blue-print: their .-framework is based on trigonaly bound carbon atoms and the remaining electron is located in a more or less delocalized .-system, responsible for the physical properties and chemical reactivity of these systems. Within this talk, the chemical reactivity of fullerenes, carbon nanotubes, and graphene are comparatively discussed. Here, the main focus is based on the reductive exfoliation/activation with subsequent covalent framework functionalization.[1,2] Novel approaches and concepts for the characterization of the polydisperse reaction products are presented.[3,4] These are the linking joint for the analysis of 2D materials beyond graphene. Therefore, the last part of the presentation will focus on the chemistry of black phosphorus.
