| Outline of Final Research Achievements |
Graphene nanoribbons (GNRs) have drawn much attention as promising materials for next generation nanoelectronic devices. Here, we report the synthesis of the simplest model compounds toward developing a bottom-up synthesis of GNRs with a self-assembled monolayer (SAM) method. The binding units for the SAM method were introduced at two termini of the central aromatic core of the model compounds, which was not only for preparing a monolayer of model compounds but also for binding a gold surface ideally. Cyclic voltammograms of gold electrodes modified with the model compounds implied that annealing the substrates at 300 degree led to cyclodehydrogenation. In addition, we have successfully synthesized precursor molecules for edge-functionalized GNR and low band gap GNR. Furthermore, theoretical analysis revealed the key intermediate states during cyclodehydrogenation for synthesizing edge-functionalized GNRs.
