Outline of Final Research Achievements

The aim of this research is to synthesize pattered molecular network on graphene moire structure. First, I found that moire pattern and domain boundary affects growth of Iron phthalocyanine on graphene. In addition, I succeeded in immobilization of a new organonitrogen compound on graphene owing to graphene and Pt(111) interaction. In the case of HOPG, this immobilization was not observed, which means that moire structure and/or Pt(111) substrate is crucial for this reaction. Moreover, this organonitogen compound might show the activity for oxygen reduction reaction because of the nitrogen site. After immobilization, nitrogen site dose not change according to XPS. Furthermore structure of this material remains even after annealing at 873 K in vacuum. From STM measurement, density of this compound is quite high. These results indicate that this material is a good candidate for a fuel cell.
