A composition is provided comprising an aqueous dispersion of polythienothiophene and a colloid-forming polymeric acid. Films from the compositions of the invention are hole injection layers of organic electronic devices comprising electroluminescent devices, such as organic light emitting diode (OLED) displays, as hole extraction layers of organic optoelectronic devices, such as photovoltaic devices, and thin film fields. It is useful as a combination with metal nanowires or carbon nanotubes in applications such as drains, sources, or gate electrodes of effect transistors.n n n n Polythienothiophenes, colloid-forming polymeric acids, aqueous dispersions. |
