  • Dispersions and films comprising conducting polymer for optoelectronic devices
    Patent number: 8920678
    Abstract: A dispersion, and a film and optoelectronic devices formed from the dispersion are provided. The dispersion comprising conducting polymer containing particles having a particle size of less than 450 nm, wherein the conducting polymer comprises substituted or unsubstituted, uncharged or charged polymerized units of thieno[3,4-b]thiophene, and wherein a film drop cast from the dispersion has a conductivity from 10?1 to 10?6 S/cm measured using the four point probe method.
    Type: Grant

    Date of Patent: December 30, 2014
    Assignee: Samsung Electronics Co., Ltd.
    Inventors: Xuezhong Jiang, Roy Daniel Bastian
  • Aqueous dispersions of polythienothiophenes with fluorinated ion exchange polymers as dopants
    Patent number: 7569158
    Abstract: Compositions are provided comprising aqueous dispersions of polythienothiophenes and colloid-forming polymeric acids. Films from invention compositions are useful as hole injection layers in organic electronic devices, including electroluminescent devices, such as, for example, organic light emitting diodes (OLED) displays, as hole extraction layers in organic optoelectronic devices, such as organic photovoltaic devices, and in combination with metal nanowires or carbon nanotubes in applications such as drain, source, or gate electrodes in thin film field effect transistor.
