Outline of Final Research Achievements

This project clarified the physical properties of π figuration system, which is aggregation of π figuration molecules, and tried to investigate new physical phenomenon and new functional devices. We investigated many molecules and succeeded in (i) the development of new chemical doping method, (ii) the fabrication of highly functionalized electric double layer transistors, (iii) the fabrication of highly functionalized light-emitting electrochemical cells, (iv) the fabrication of mechanical flexible devices, and (v) strain induced phase transition.

Academic Significance and Societal Importance of the Research Achievements

本研究により、有機材料における高密度なキャリ数制御方法が新たに示された。これは、超伝導転移やレーザー発振などの様々な物性制御や高機能化につながる重要な知見である。加えて、本研究では歪みや各種外場による変調が有機材料に与える影響を明らかにしつつ、これらを利用した様々な物性制御や高機能化も実現した。これは、これまでのアプローチとは一線を画しており、今後発展が期待される。
