Graphene, a 2D honeycomb network of sp2-hybrized carbon atoms, attracts considerable attention in many research fields because of its extraordinary mechanical and electronic properties. Despite such superb aspects originating from extended π-conjugation, graphene is not easy to handle, process, and modify. Hence, chemists have been motivated to develop its analog that are able to avoid such problems. Hexabenzocoronene derivatives, which have been named “molecular graphene,” are one of the representatives of such structural analogues. They consist of 13 fused benzene rings and are readily available by oxidative cyclization of hexaarylbenzene derivatives. The development of this synthetic protocol has made it possible to design “soft organic graphite” by supramolecular chemistry. As expected from the π-stacked architecture of graphite, such graphite-like organic materials, formed by the assembly of molecular graphenes, display interesting properties such as anisotropic charge carrier transport. This chapter describes the historical background of the synthesis of molecular graphenes and highlights fabrication and properties of their one-dimensionally assembled nanostructures with fibrous and tubular morphologies.
