Outline of Final Research Achievements |
In this research, the principal investigator and coworkers have a high degree of originality, focusing on "molecular vibration" and "molecular orbital overlap" by "molecular orbital engineering" in addition to "molecular shape engineering" based on band transport theory. Thus, the molecular design was demonstrated successfully. Through a series of researches from molecular design to device application, we have developed practical available and band transporting organic semiconductors with high carrier mobility.
