| Outline of Final Research Achievements |
Several types of new multi-electron redox oligomers were successfully synthesized. The redox behavior of the obtained molecules was elucidated by cyclic voltammetry. A rechargeable battery using a dimeric TTPY with cyclohexene inserted as a positive electrode material exhibits relatively high charge-discharge performance. X-ray structure analysis and electrical conductivity measurement of the cation radical salt based on a trimeric TTF with different substituents were successful, and revealed that its electronic state is charge ordered state or a Mott insulator. Furthermore, it was found that a trimer in which one of the TTF units is replaced with TSF exhibits metallic conductivity at around room temperature.
