| Outline of Final Research Achievements |
The rigid macrocyclic compounds incorporating electron-rich pi-electron units exhibit interesting electronic properties and oxidation behaviors. In this study, we have developed the efficient synthesis of nitrogen-containing macrocycles and elucidated their redox behavior. We succeeded in the synthesis of the various macrocycles that differed in substitution positions of the anthrylene unit linked by nitrogen, and the electronic properties of the oxidized species were determined by the electronic spectra and DFT calculation. In particular, the nitrogen-containing macrocycles incorporating 9,10-anthrylene units exhibited specific electronic properties due to their structural factors. We have established the novel macrocyclic molecular design utilizing the structural features of anthracene.

本研究で開発した含窒素大環状分子は，適切な置換位置で連結したアントラセン骨格を組み込むことで新奇な電子構造を発現することを見出した．アントラセン骨格の構造的な効果に基づく分子設計は，これまで主流であったパイ電子系の拡張による電子物性の発現とは異なり，従来にないアントラセン骨格の利用法として新しい分子構造と電子物性を引き出すことができた．今後，これらの分子設計指針を利用することで電子豊富な分子系の構築とそれらを利用した電荷とスピンを制御・利用するスピンエレクトロニクス分野や高いドナー性を利用した正孔輸送材料など有機機能性材料の開発などへ大きな波及効果があると考えられる．
