| Outline of Final Research Achievements |
In this research, we first aim to search unexplored organic semiconductor frameworks, and then based on such frameworks, to control molecular arrangement and orientation in molecular assembly at molecular design stage. Rational molecular design, organic synthesis, single crystal structure analysis, thin film structure analysis are the key methods in the project. In the actual project, development of unexplored frameworks and control of higher-order structures, and further development of organic semiconductors contributing to the realization of high-performance transistors and organic thin-film solar cells have been done; novel n-type semiconductor frameworks such as naphthothiophene imide and acedidithiophenedione and extended thienoacenes as p-type semiconductor frameworks are developed; high-performance materials and devices are developed based on them. Furthermore, a method of crystal structure control of semiconducting molecules based on molecular modification is established .
