| Research Abstract |
Novelπ-conjugated hetero-and carbocyclic compounds have been developed based on new synthetic methodology of "modular synthesis", aiming at improvement in efficiency of organic electronic devices as well as proof of principle of innovative concepts of devices. Noteworthy is that the versatility of fused furans has been found out to serve as stable and high-performance semiconducting materials. For example, an ambipolar benzodifuran allowed us to fabricate efficient homojunction OLED that emit light across the full visible color range and perform at a level close to the theoretical limit. A naphtodiduran showed even higher mobility than amorphous silicon. Novel stable n-type materials, such as benzophospholes and bis(cinnoline) s have been also developed, and their versatility has been demonstrated by applying them to cathode buffer materials in thin-film solar cells. Multifunctional materials, such as highly emissive ambipolar material, near infrared-light absorbing/emitting materials, have been successfully obtained as well.
