<p>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.</p>
