Graphene nanoribbons (GNRs) combine the advantages of pristine graphene with the semiconducting properties required for applications in organic electronics. The properties of GNRs are significantly dependent on their structural variables such as molecular length, width and edging structures. However, it remains quite challenging to achieve atomically precise control over the structures of GNRs simultaneously, therefore new synthetic approaches are highly desirable. In this proposal (WavyRibbons; Wavy N-doped Graphene Nanoribbons for Single Molecule Electronics), a novel synthetic approach is proposed to afford GNRs with controllable length, wavy (hybrid armchair and zigzag) shape and N-doping. The properties of these GNRs will be fully characterized. These structure defined GNRs bearing suitable ending groups also provide a unique platform to study the charge transport properties in single molecule junctions, which will shield new insights into this important but unexplored field. The appropriate working plan taking into account 1) background of the fellow; 2) experience of the host groups; 3) resources available will ensure the achievement of this proposal. And, the success of WavyRibbons will not also signify a real breakthrough in fundamental research but also benefit all the parties involved.
