Abstract
A graphene nanoribbon has a chiral edge to which a dicarbimide structure is bonded. The dicarbimide structure is an electron-withdrawing group. The width and band gap of the graphene nanoribbon are controlled by a precursor molecule used for a polymerization reaction. Furthermore, n-type operation of the graphene nanoribbon is realized by the dicarbimide structure. In addition, with the graphene nanoribbon, an increase in ribbon length and suppression of a polymerization defect by the stabilization of a reaction intermediate of the precursor molecule, as well as improvement in orientation are realized by the dicarbimide structure.
