Outline of Final Research Achievements

Charge transfer complexes based on a highly symmetric (D6h) polycyclic aromatic hydrocarbon, coronene, were systematically prepared. For the mixed-stacked neutral complexes, we found that the dynamic properties of coronene molecules largely depend on the molecular arrangement within the stacks.
The first coronene cation solid was prepared by electrooxidation. The salt belongs to the cubic system, which is exceptionally rare among molecular solids, and has no face-to-face π-π interactions. It shows a high room-temperature conductivity (1.7 Scm-1), although exhibiting semiconducting behavior associated with the charge disproportionation.
In addition, we obtained the coronene cation salts with π-stacking columns of coronene. The salts have interplanar distances shorter than that in graphite and show semiconducting behavior. For the salts, we succeeded in the first observation of a static Jahn-Teller distortion of coronene cations.
