At the nanoscale, the electronic properties of graphene vary significantly depending on its shape and chemical modification. Although many experimental and theoretical studies have been conducted on the electronic properties of nanographene, experimental characterization has been insufficient. This is mainly due to the difficulty in fabricating graphene with precisely controlled shapes and chemical structures and in accurately identifying the nanographene structure at the atomic level. In this paper, we describe the electronic properties of graphene nanostructures with different geometries and chemical structures, which were characterized by scanning probe microscopy (SPM). SPM showed that the atomic-level shape and chemical modifications significantly impacted the electronic properties of graphene. Furthermore, small π-conjugated molecules associated with fullerenes and aromatic molecules between metal electrodes can be regarded as nanographene. Additional electronic and transport properties can be derived by modulating the intermolecular and metal–molecule interactions of nanographene molecules. Studies on the control of the intermolecular and metal–molecule interactions of chemically modified aromatic molecules and the associated modulation of the electronic structure and charge transport properties are presented.
