The present invention can provide a graphene nanoribbon having at least one structural unit represented by the following general formula by a method with a small number of steps and suppressed side reactions. In the formula, the dashed lines are the same or different, and represent no bond or single bond; *1 represents a bonding point; when the dashed line bonded to *2 is a single bond, *2 represents a bonding point; R 3a , R 3b , R 3c and R 3d are the same or different, and represent a hydrogen atom, a halogen atom, an alkyl group, a cycloalkyl group, a (poly) ether group, an ester group, a monovalent aromatic hydrocarbon group or a monovalent heterocyclic group; R 3a and R 3b , And at least one group of R 3c and R 3d is optionally bonded to each other to form a ring. |
