| Outline of Final Research Achievements |
Aromatic hydrocarbons with two or more fused benzene rings are called polycyclic aromatic hydrocarbons (PAH). Organic compounds with promising properties as semiconductors were prepared by replacing the carbon atoms of PAH with nitrogen atoms, oxygen atoms, and/or sulfur atoms. New short-step synthetic methods were developed for the connection of two aromatic rings with a bridge structure containing nitrogen atoms. This method was successfully applied to syntheses electron-deficient aromatic compounds containing many nitrogen atoms. In addition, non-planar fused ring compounds and quinoid compounds were synthesized. These compounds are expected to exhibit unique properties. The crystal structure, electronic properties, and chemical reactivity of these compounds were clarified.

有機ELディスプレイを代表とする有機デバイスの性能向上のかぎとなるのは、高性能有機半導体の開発である。有機半導体の開発に必要な電子不足性の有機化合物は、効率的な合成技術の欠如から種類が少なく技術革新が求められてきた。本研究では、この要請に応えることができる短工程の合成技術を開発し、従来技術では合成できない電子不足性の有機化合物を創出した。また、特異な性質の発現が期待できる有機化合物を合成し、有機半導体として有望な性質を明らかにした。本研究の成果である新規合成法の開発および新規材料の創出は、高性能有機半導体の供給に貢献し有機太陽電池などの次世代有機デバイスの実用化を促進する。
