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.
