| Outline of Final Research Achievements |
In this research, I have worked on the development of novel semiconducting polymers toward the improvement of the properties of organic electronic devices. Some of the polymers synthesized here demonstrated charge carrier mobilities of more than 1 cm2/Vs, which is very high for polymers, and/or exhibited not only p-channel behavior but also ambipolar behavior in organic field-effect transistors. Furthermore, a power conversion efficiency of 10% was achieved in solar cells using a polymer synthesized in this work. It was found that the molecular orientation can be controled by the molecular design, and the device properties varied dependent on the molecular orientation.
