| Outline of Final Research Achievements |
We understand two major electronic features of graphene, "edge state" and "Dirac point" at the molecular level using chemically synthesized model molecules and elucidate the unique electronic properties derived from its characteristic electronic structure. For the study of the edge state, we succeeded in developing a reaction to form the main skeleton by combining aromatic rings and acetylene and finally filling the cob region to form zigzag edges. Regarding the Dirac point, attempts were made to synthesize new two-dimensional symmetric molecules and two-dimensional integration, and actually succeeded in forming a two-dimensional honeycomb lattice. Furthermore, we investigated the rate of the electron transfer reaction occurring between the three blades, and obtained information serving as a clue to determine the electron transfer rate in the stack.
