| Outline of Final Research Achievements |
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.
