  • Patent number: 7837901
    Abstract: There are provided electrically conducting polymer compositions comprising an electrically conductive polymer or copolymer and an organic solvent wettable fluorinated acid polymer. Electrically conductive polymer materials are derived from thiophene, pyrrole, aniline and polycyclic heteroaromatic precursor monomers. Non-conductive polymers derived from alkenyl, alkynyl, arylene, and heteroarylene precursor monomers. The organic-solvent wettable fluorinated acid polymer is fluorinated or highly fluorinated and may be colloid-forming. Acidic groups include carboxylic acid groups, sulfonic acid groups, sulfonimide groups, phosphoric acid groups, phosphonic acid groups, and combinations thereof. The compositions can be used in organic electronic devices.
