Application of Thin Films of Polyaniline and Polypyrrole in Novel Light-Emitting Devices

Abstract

Light-emitting electroluminescent devices are described in which the conjugated light emitting polymer is separated from one or both of the device electrodes by a film of non-conducting polyaniline. Novel electrochemically-driven electroluminescent devices are also described. The effect on the properties of polypyrrole or polyaniline (deposited from aqueous polymerizing solutions of the monomer) caused by the hydrophilicity/hydrophobicity of the substrate surface is utilized by a 'microcontact printing' technique to form patterned liquid crystal display devices.
