    • The present invention is directed to methods of fabricating electrically conducting polymers and precursors thereof in which the polymer has a controlled level of aggregation and morphology. This is done by controlling the rate of polymerization and the rate at which the polymer precipitates from solution during the polymerization reaction. An additive is added to the polymerization medium, said additive increasing or decreasing the rate at which the polymer precipitates from the reaction medium. When said additive is a second organic solvent, the polymerization reaction proceeds homogeneously for a longer period of time than does the corresponding polymerization reaction which does not include said additive. Control of the polymerization kinetics allows control of the morphology for the isolated polymer and in turn control of the properties of these polymers.
