Abstract

There is provided a transparent conductor including conductive nanoparticles and at least one of (a) a fluorinated acid polymer and (b) a semiconductive polymer doped with a fluorinated acid polymer. The nanoparticles are carbon nanoparticles, metal nanoparticles, or combinations thereof. The carbon and metal nanoparticles are selected from nanotubes, fullerenes, and nanofibers. 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 semiconductive polymers comprise homopolymers and copolymers derived from monomers selected from substituted and unsubstituted thiophenes, pyrroles, anilines, and cyclic heteroaromatics, and combinations of those. The compositions may be used in organic electronic devices (OLEDs).
