Outline of Final Research Achievements

Excitons, which are formed in a molecule when electrons and holes combine, are the source of various functions of molecules such as luminescence, photovoltaic effect, and photochemical reactions. In this study, I tried to investigate the exciton formation between p- and n-type hetero molecular dimers using luminescence measurements based on scanning tunneling microscopy, a microscope for visualizing a single molecule. In this study, I designed and constructed an evaporator to create molecular hetero dimers. After the end of the research period, I will continue optical measurements on the excitons formed in the model hetero molecular dimers.

Academic Significance and Societal Importance of the Research Achievements

分子界面における励起子の挙動は様々な光化学機能の根源であり、これまで溶液系や固体凝集系における解析がなされてきた。本研究のように基板上にモデル分子系を作成し、光学測定を試みるアプローチはこれまでなく、新たな分子科学の展開ができると期待される。特に、本研究のモデル分子系は構造をよく規定出来ることから計算化学との親和性が高く、理論科学者との共同研究も進めている。モデル分子系における最適な空間配置を実験・理論の両面から理解することで新たな高効率な有機発光デバイスの実現に繋がると期待される。
