LIGHT EMITTING ELECTROCHEMICAL CELLS WITH BAND-EDGE ENHANCED LIGHT EMISSION DUE TO CHIRAL LIQUID CRYSTALLINE STRUCTURE

摘要

Light emitting electrochemical cell devices comprising chiral liquid crystalline materials. The chiral liquid crystalline material mixtures of the devices function as both electrolytes and as light emitting materials. The chiral liquid crystalline material mixtures also form photonic crystal structures creating a photonic stop band. The presence of the photonic stop band enables the light emitting electrochemical cell devices to emit light with improved energy efficiency.
