| Outline of Final Research Achievements |
I have investigated the organic transistor materials having supercooled liquid crystal phase in order to realize both high solution processability and high thermal durability of polycrystalline thin films. The developed materials having a supercooled liquid crystal phase show high solution processability at room temperature and high FET mobility over 10cm2/Vs after thermal annealing at 120 oC for 5minutes, despite of polycrystalline thin films. Furthermore, the high mobility is hardly changed after thermal stress up to 140 oC because the materials have an asymmetric phase transition behavior in cooling and heating process. I succeeded the development of quality organic transistors materials having high solution processability, high thermal durability, and high mobility.
