| Outline of Final Research Achievements |
We proposed a stretchable organic material composed of a pyrene-based liquid organic semiconductor and an elastomer. The prepared material was found to be stretched to three times its normal size. Organic light-emitting diode (OLED) consisting of the stretchable emitting layer exhibited greenish-blue electroluminescence. We believe that the proposed stretchable emitting material will be useful in developing novel light-emitting devices.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で作製した伸縮性機能薄膜を有機ELの発光層として用いることで、大気下で電界発光が得られることが明らかになった。今後、電子物性およびナノ・マイクロデバイス設計の観点から当該材料の性能をさらに引き出すことで、衣類や肌などに装着可能なウェアラブルディスプレイや、自由曲面や関節部位に実装可能な医療ロボット用センサーへの応用も期待される。
