Outline of Final Research Achievements |
In order to develop new molecular materials showing intriguing physical properties and functions, we have demonstrated the material exploration based on the spin-delocalized organic neutral radical, trioxotriangulene (TOT). We prepared the mixed-valence salts containing neutral radical and anion species of TOT derivatives having various substituent groups by the electro-crystallization under the existence of countercations of various sizes. The salt of chlorinated TOT with lithium exhibited a high conductivity equal to those of the charge-transfer complexes showing metallic conducting behavior. Furthermore, the mesoporous TOT silica, the porous silicate containing neutral radical of TOT, was successfully synthesized. The lithium-ion secondary battery containing the mesoporous TOT silica as a cathode-active materials showed a high discharge capacity and cycle performance
