This synthesis is well known on coinage metals, namely, Cu, Ag, and Au, which possess a high electron density. To study these unique

• difference of graphene nanoribbons fabricated by on-surface synthesis on Au(111). The GNRs can be clearly discerned from the substrate through their topography, but also through their contact potential difference. GNRs have a measured contact potential that is about 100 meV smaller than that of a Au

• chains have a great influence on the formation of 2D nanoarchitectures. Recent advances in 2D self-assembly include “on-surface synthesis,” “in situ reactions” such as metal coordination, “correlation of the 2D and 3D structures (crystal structures)” for revealing the origins of physical properties, and

Müllen, Fasel, and co-workers have succeeded in nanoarchitectonics of graphene nanoribbons with zigzag edges with atomic precision by on-surface synthesis via cyclodehydrogenation of precursor monomers [123]. The physical properties of the graphene nanoribbons, such as band

Various functional units can be freely combined to obtain new nanostructures. However, it is generally
