  • Liquid crystalline organic semiconductor material and organic semiconductor device using same
    Patent number: 9059410
    Abstract: The present invention provides a novel organic semiconductor material that affords efficient charge transport, under a wider range of conditions, by increasing the temperature stability and expanding the temperature range of the organic semiconductor material. In an organic semiconductor material comprising a liquid crystalline compound having substituents on the periphery of a rigid plate-like central structure, the substituents have a fluorinated phenylene group, and columns in which the molecules of the compound are accumulated in a stack are aligned hexagonally.

  • Molecular orientation controlling method and molecular orientation controlling device
    Publication number: 20040239854
    Abstract: The present invention relates to a minute molecular orientation controlling comprising the steps of specifically exciting the vibration energy level of an intramolecular chemical bond of a molecular material by using infrared light to locally and anisotropically heat the molecule and hence cause a thermal non-equilibrium state, and then selectively re-orienting in the specific direction of in-plane and out-of-plane directions with respect to a plane perpendicular to the incident axis dependent on the incident direction and polarization direction; and a device for controlling the process.
