Outline of Final Research Achievements

Graphene nanoribbons (GNRs) are expected to show excellent properties, which depends on their molecular width and edge-structures. Bottom-up syntheses of GNRs are indispensable method for fabrication with atomically-precise controlled manner. We established effective GNR synthesis as 2-zone chemical vapor deposition method. In this project, I proposed synthesis of asymmetrically edge-functionalized GNRs. We found molecular torsion on surface plays a critical role on surface reaction. We reported biomimetic surface polymerization and strain-induced skeletal rearrangement. These findings pave the way to create new bottom-up nanocarbon materials.
