Outline of Final Research Achievements

The purpose of this study is to develop a new synthetic method for preparing graphene　nanoribbons (GNRs) that have zigzag and asymmetrically functionalized edge structures and to investigate for applications as a functional materials. With our method, we succeeded in the preparation of asymmetrically functionalized GNRs that has never been reported. By an introduction of electron-rich substituents, GNR having large dipole moment was obtained. The optical and electronic properties of asymmetric GNR was clarified.
