On-surface synthesis is a newly developing field of research that aims at making use of well-defined solid surfaces as confinement templates to initiate chemical reactions. The concepts of supramolecular chemistry are here applied to provide well-defined functional surfaces from the “bottom-up” self-assembly of nanometer-sized elementary building-blocks. The interest for creating covalent nanoarchitectures directly on surfaces is manifold. On-surface synthesis gives access to original reactions mechanisms in mild conditions that would be not easily accessible in standard chemistry conditions. Also, it represents an efficient route to the formation of robust organic networks and 2D polymers. Finally, the full range of available surface science techniques can deliver exquisite characterization of the different reaction processes with atomic precision.
