On-surface synthesis (OSS) defines a special opportunity to investigate intermolecular coupling at. sub-molecular level and has delivered many appealing polymers but so-far OSS is limited to the. lateral covalent bonding of molecular precursors. Here, the authors demonstrate cycloaddition. between C60 and an aromatic compound allowing covalent coupling perpendicular to the surface and multiple non-planar covalent coupling of C60.
