| Outline of Final Research Achievements |
Mono-alkylated liquid crystalline molecules, which have an alkyl side chain with conjugated aromatic system that is carrier transport moiety, give us organic transistor having high mobility, because the crystalline structure is bilayered crystal structure of aromatic systems and increases the carrier transport path on inter layers. Thin films having the bilayered crystal structure are fabricated from the film having mono layered crystal structure via uniform liquid crystalline films by thermal or solvent vapor annealing. These bilayered crystal structure and organic transistors having high mobility are also realized by other mono-alkylated liquid crystalline molecules. Thus, mono-alkylated liquid crystalline organic semiconductors are a good candidate as organic transistor materials having good solution processability and high mobility.
