  • Organic thin film transistor, organic semiconductor thin film, and organic semiconductor material
    Patent number: 9714253
    Abstract: An organic thin film transistor having a semiconductor active layer containing a compound represented by the formula (1) has a high carrier mobility and a small change in the threshold voltage after repeated operation. R1 to R10 represent H or a substituent, provided that at least one of R1 to R4 and R6 to R9 represents a substituent represented by -L-R, L represents a specific divalent linking group, and R represents an alkyl group, an oligooxyethylene group, an oligosiloxane group, or a trialkylsilyl group.
    Type: Grant
    Filed: February 26, 2015
    Date of Patent: July 25, 2017
    Assignee: FUJIFILM Corporation
    Inventors: Tetsu Kitamura, Koji Takaku, Wataru Sotoyama, Yuki Hirai, Masaru Kinoshita, Yuuta Shigenoi
