  • Polyacene compound and organic semiconductor thin film
    Patent number: 8236998
    Abstract: The present invention provides an organic semiconductor material which exhibits a high mobility, and excellent solubility in solvents and oxidation resistance. The present invention also provides an organic semiconductor thin film exhibiting a high mobility, and an organic semiconductor device exhibiting excellent electronic characteristics. A transistor structure is formed by coating the silicon substrate with a thin film of pentacene compound substituted halogens at 6 and 13 positions and aliphatic hydrocarbons at 2, 3, 9 and 10 positions, wherein the substrate is patterned beforehand with gold to have a source and drain electrodes.
    Type: Grant
    Filed: January 5, 2012
    Date of Patent: August 7, 2012
    Assignee: Asahi Kasei Corporation
    Inventors: Kazuto Nagata, Yoshinori Naruta, Masatoshi Yakiyama
