Surface-assisted synthesis of 0-, 1-, and 2-dimensional structures — •Katayoun Gharagozloo-Hubmann, Niclas Sven Mueller, Christian Lotze, Katharina J. Franke, and Stephanie Reich — Department of Physics, Freie Universität Berlin, Arnimallee 14, 14195 Berlin, Germany

The on-surface synthesis of graphene nanoribbons based on halogenated unsaturated hydrocarbons is an already known and often used concept.[1] Molecular precursors were designed that led to the synthesis of ribbons with different symmetry and width.[2]

We propose a novel concept for the on-surface synthesis of 0-, 1-, or 2-dimensional structures. We suggest to select the target precursor from commercially available molecules and use the template substrates for the growth of graphene substructures. We already demonstrated the growth of 2D graphene, when using extended metal substrates.[3] This concept not only provides access to the various graphene substructures, but also impressively demonstrates the use of weak molecular interactions for the production of more complex structures via covalent coupling.
