disclosed are methods of dispersing sulfonated polythiophenes in a non - aqueous solvent including replacing water for organic solvent without precipitation of the polythiophene . once dispersed in a non - aqueous solvent , the sulfonated polythiophene can be mixed with a matrix polymer . the materials can be used in organic electronic devices including oleds and opvs . the solvent processes can improve the viscosity properties . sulfonated regioregular polythiophenes can be used . a benefit is improved solvent compatibility in building organic electronic devices and improved ability to formulate with matrix materials .
