Compositions are provided comprising a continuous liquid aqueous medium having dispersed therein a polydioxythiophene and at least one colloid-forming fluorinated polymeric acid. Films from invention compositions are useful as buffer layers in organic electronic devices, including electroluminescent devices, such as, for example, organic light emitting diodes (OLED) displays.

Water dispersible polythiophenes made with polymeric acid colloids

Devices are provided comprising conductive or semiconductive layers comprising compositions comprising aqueous dispersions of polythiophenes having homopolymers or co-polymers of Formula I(a) or Formula I(b) and at least one colloid-forming polymeric acid. Methods of making such compositions and using them in organic electronic devices are further provided.

The invention relates to conductive polymer composites comprising a first layer comprising at least one electrically doped conductive polymer and a second layer comprising at least one material selected from a colloid-forming polymeric acid, a salt of a colloid-forming polymeric acid, a non-polymeric fluorinated organic acid, and a salt of a non-polymeric fluorinated organic acid.

Conductive polymer composites

There is provided an electrically conductive polymer composition, comprising a first electrically conductive polymer doped with an organic solvent wettable fluorinated acid polymer in admixture with a second electrically conductive polymer doped with an organic solvent non-wettable fluorinated acid polymer.

Electrically conductive polymer compositions

The present disclosure relates to electrically conductive polymer compositions, comprising at least one electrically conductive copolymer; and at least one fluorinated acid polymer, their use in organic electronic devices, and methods for preparation.

Electrically conducting polymer compositions are provided. The compositions comprise homopolymers and copolymers of polythiophene, polypyrrole, polyaniline, and polycyclic heteroaromatics, and combinations of those, in admixture with an organic solvent wettable fluorinated acid polymer. The acid polymers are fluorinated or highly fluorinated and have acidic groups including carboxylic acid groups, sulfonic acid groups, sulfonimide groups, phosphoric acid groups, phosphonic acid groups, and combinations thereof. The compositions may be used in organic electronic devices (OLEDs).

Compositions are provided comprising aqueous dispersions of polythiophenes and colloid-forming polymeric acids. Films from invention compositions are useful as buffer layers in organic electronic devices, including electroluminescent devices, such as, for example, organic light emitting diodes (OLED) displays in combination with metal nanowires or carbon nanotubes in applications such as drain, source, or gate electrodes in thin film field effect transistors.

Compositions are provided comprising aqueous dispersions of polythiophenes having homopolymers or co-polymers of Formula I(a) or Formula I(b) and at least one colloid-forming polymeric acid. Methods of making such compositions and using them in organic electronic devices are further provided.

Water dispersible substituted polydioxythiophenes made with fluorinated polymeric sulfonic acid colloids

The energy levels (HOMO, LUMO) of the conjugated polymer are tuned independently, so that an energy match on both sides of the device can be accomplished while keeping the emission color in the blue region. Such polymers can be formed by polymerization of a mixture of monomers. The mixture of the monomers contains at least one monomer having an electron-deficient group sandwiched by two aromatic hydrocarbon groups ('Monomer (I)') and at least one hole transporting ('HT') monomer. The mixture of monomers may also contain a solubility enhancement (&#x201c;SE&#x201d;) monomer and/or a Branching Monomer. Such polymers can be used in fabricating light emitting diodes to achieve some of the best device performance to date including high efficiency and blue color purity.
