Abstract : Light emitting electroluminescent devices have been studied in which the conjugated light emitting polymer is separated on both sides from the device electrodes by a film of non-conducting polyaniline. The devices operate under an AC applied potential. Aluminum, copper, or gold serve as the metal electrodes. Flexible, completely organic polymer dispersed liquid crystal light valves have been fabricated from transparent plastic substrates on which a conducting film of polypyrrole has been deposited. A new concept, 'microcontact printing', is being investigated for patterning the polypyrrole.
