Light Emitting Electrochemical Cells Based on Ionic Iridium Complexes and Ionic Conductor Blend as the Active Layer.

Recently, light emitting electrochemical cells (LECs) have received considerable attention for their application in display and lighting applications. In this manuscript we put forward a study of cationic iridium complex and ionic conductor blend as the active layer of light emitting electrochemical cells. Tetrabutylammonium triflate functions as an ionic conductor. We have synthesized iridium metal complex using phenanthroline based ancillary ligands and studied light emitting properties of the devices in pristine as well as ionic conductor blends. Current density, luminescence plots were well studied against applied bias and on comparison, the devices with ionic liquids showed better performance. [ABSTRACT FROM AUTHOR]
