Abstract :研究成果の概要(和文):分子性導体において空間反転対称性の欠如に伴う新しい強相関電子物性を開拓するため,縮小π電子系ドナーやTTP系ドナーにキラリティーを導入したキラルドナー,およびそれらの電荷移動塩を合成し,構造と物性を明らかにした。キラルな縮小π系ドナー(S,S)-DM-MeDH-TTPのラジカル塩の磁性および超高圧下の電気物性を明らかにし,常圧における絶縁相の電子状態を解明した。(S,S)-DMDHDA-TTPをはじめとする種々のキラルTTP系ドナーを新たに合成し,電荷移動塩の電気物性および構造とバンド構造を明らかにした。キラリティーの効果を解明するため,対応するラセミドナーを合成し,構造と物性を明らかにした。研究成果の概要(英文):In order to explore new solid state properties of molecular based strongly correlated electron systems with a lack of spatial inversion symmetry, organic chiral electron donors composed of reduced π-electron system donors and TTP-donors, and their charge transfer salts were newly synthesized. Magnetic and transport properties of the radical salts of the chiral π-reduced donor (S,S)-DM-MeDH-TTP have been investigated, and the electronic state of the insulating state at ambient pressure was revealed to be a charge order state. We also succeeded in the syntheses of new chiral TTP donors including (S,S)-DMDHDA-TTP, and revealed the physical properties, crystal structures and band structures. Furthermore, syntheses, structure analyses, and measurements of physical properties of the corresponding racemic donors have been carried out to investigate the effect of chirality.
