| Outline of Final Research Achievements |
The realization of three-dimensional (3D) interaction in organic molecular conductors and p-type semiconductors has not yet been much researched. In this study, we investigated the design and synthesis of new donor molecules with 3D interaction capable of being expected by developing end-to-end interaction induced by chalcogen atoms that are introduced into the terminals of molecule along the molecular long axis, in addition to two-dimensional side-by-side interaction caused by sulfur atoms that are introduced into both sides of the molecule. Our further search was made for conductivity and mobility based on the three-dimensionality.

| Academic Significance and Societal Importance of the Research Achievements |
有機超伝導体を始めとした分子性導体のドナー成分および有機電界効果トランジスタ(OFET)に用いられているp型半導体の開発研究では，これまで二次元的相互作用の発現が主流であった。本研究では，三次元的相互作用を発現する新しいドナー分子を構築するための合成戦略を打ち出し，弱いながらも三次元的相互作用が示唆されるドナー分子の構築に成功した。この合成戦略に従ってドナー分子の設計・合成をさらに行えば，三次元性に基づく高温有機超伝導体や高性能OFETの開発に繋がることが期待される。
