Abstract

Recent advances in state-of-the-art probe microscopy allow us to conduct single molecular chemistry via tip- induced reactions and direct imaging of the inner structure of the products. Here, we synthesize three-dimensional graphene nanoribbons by on-surface chemical reaction and take advantage of tip-induced assembly to demon- strate their capability as a playground for local probe chemistry. We show that the radical caused by tip-induced debromination can be reversibly terminated by either a bromine atom or a fullerene molecule. The experimental results combined with theoretical calculations pave the way for sequential reactions, particularly addition reac- tions, by a local probe at the single-molecule level decoupled from the surface.
