| Outline of Final Research Achievements |
In this work, we succeeded in the arrangement of quantum dots (nano-sized semiconductors) by using self-assembly of perylene bisimide organic molecules. Furthermore, in the system using azobenzene derivatives with a hydrogen-bonding moiety, we revealed the formation of the highly ordered arrangements of quantum dots and azobenzene derivatives. In addition, we found that the arranged structures can be changed by the photoirradiation, leading to an increase in photoluminescence intensity.

| Academic Significance and Societal Importance of the Research Achievements |
本研究により、これまで困難とされていた「量子ドット（ナノサイズの半導体）を並べること」における新たな指針を提示することが出来た。この手法を応用することで、高秩序なハイブリッド材料の作製が可能となり、より高性能・高機能な発光・光電子材料の開発に繋がる。以上より、本研究成果は、材料科学の発展のための重要な知見であると言える。
