Abstract
A surface modified electrode comprising at least one conductive layer, and at least one reduced polymeric material, wherein the reduced polymeric material comprises at least one additional electron relative to a corresponding neutral polymeric precursor; and at least one cationic species is provided. Coating compositions and coated articles comprising the reduced polymeric materials are also provided. The coating compositions lower the work function of the electrode surface, thereby facilitating the production of more efficient electrooptic devices.
