Application of Gold and Copper Electrodes in Pyridine-Vinylene Based Conjugated Polymer Light Emitting (SCALE) Devices

摘要

Conjugated polymers have been studied extensively for their electrical conductivity, interesting optical, and more recently, electroluminescent properties. Conjugated polymer light emitting diodes (CPLED's) were first reported in 1990 using poly(phenylene vinylene), (PPV), as the light emitting material.rnPreviously, we have reported on the electroluminescent properties of a copolymer of a derivative of PPV and the nitrogen analog of PPV, poly(2,5-dihexadecanoxy phenylene vinylene pyridyl vinylene), (PPV.PPyV) in a variety of different device configurations some of which can be operated in forward and reverse bias modes between copper and ITO glass substrates thus enabling operation in an AC mode. Some of these involve a 5-layered symmetrically configured AC driven light-emitting (SCALE) configuration.
