| Outline of Final Research Achievements |
A π-conjugation system comprising three azulene units, terazulenes, exhibits excellent n-type transistor performance. These results represent an unconventional concept: polarity control of OFET achieved by molecular orbital distribution control, which provides a new strategy for the molecular design of semiconductor materials.
To resolve a trade-off between orientation and solubility for organic semiconductor materials, we have focused on bent scaffolds based on a thieno[2,3-b]thiophene unit. The bent-shaphed acenes showed high solubility in ordinary organic solvents. These results indicate that the bent-shaped thienoacene combine the significant characteristics of solubility, stability, and molecular orientation.
