Graphene nanoribbons present intriguing electronic properties due to their characteristic size and edge shape, and have been suggested for a wide range of uses from electronics to electromechanical systems.

We propose the use of hierarchical assemblies of graphene nanoribbons connected through hydrogen bonds, inspired by biological structures found in nature such as proteins and DNA macromolecules. The selective and directional binding of the hydrogen bond enables the design and synthesis of scalable graphene nanoribbon materials linking nano to macro.
