| Outline of Final Research Achievements |
In this study, we have investigated the mechanism of the doping of organic semiconductor materials, which is one of the key technology in the next-generation organic electronics, with a special stress on the importance of the molecular arrangement. For this purpose, we utilized well-ordered organic films that can be doped precisely, and their molecular-level structure and electronic structure were determined in-situ. We especially focused on the alkali-metal doped aromatic molecules that show variety of interesting electronic transitions. We found that the most of the systems undergo the change in the molecular arrangement upon the doping of alkali metals, suggesting the significant correlation between molecular arrangement and electronic structure. In the present study, this correlation of the structure and electronic properties was also demonstrated in the non-doped films, where we demonstrated the control of the electronic and optical properties.
