The application of an electric field ( E cast ) during solvent vaporization is shown to inhibit the formation of ordered domains in thin films of a poly(phenylenevinylene) derivative, resulting in a homogeneous environment favorable for charge transfer. An order‐of‐magnitude increase in charge‐carrier mobility (see Figure) is achieved by the elimination of these commonly found domains.
