| Outline of Final Research Achievements |
DNF-V derivatives with bromine atoms were synthesized and purified on a gram scale. Success. DNF-V derivatives with various pyridyl groups were efficiently synthesized. Based on the findings obtained in this study, asymmetric DNF-L and DNT-L were designed and synthesized. These molecules have mobility comparable to that of amorphous silicon, very low threshold voltage. In this study, it was found that even fused pi compounds without any alkyl groups can satisfy the solubility requirement for organic transistor materials by designing an appropriate way to link the pi system.

| Academic Significance and Societal Importance of the Research Achievements |
本研究および以前の研究で得られた知見を元にDNF-L, DNT-Lを設計・合成し、大スケールで得ることができた。従来の有機半導体分子は溶解度を賦与させるために長鎖アルキル基を導入することが一般的であったが、本研究において、必ずしもそれは必要でなく、パイ系のネットワークをうまくコントロールすれば、導電性を賦与するパイ系しか持たない分子でも十分な移動度が得られることを示した。これは今後の有機半導体の分子設計において重要な知見であると考えられる。
