제목 Effect of ionic liquids on the electroluminescent properties of yellow light-emitting electrochemical cells based on a iridium complex
초록 LECs are optoelectronic devices consisting of a single active component of either ionic transition metal complex (iTMC) or inorganic salt incorporated conjugated polymer sandwiched between two metal electrodes. Herein we have synthesized a new cationic iridium complex [Ir(ppz)2(dmphen)]PF6 and characterized by spectroscopic and photophysical methods. Light-emitting electrochemical cells (LECs) were fabricated using the resulting complex and their electroluminescent properties were investigated. LECs based on [Ir(ppz)2(dmphen)]PF6 gave a yellow electroluminescence of 4052 cd m-2 at 9.0 V. Furthermore, the luminance of the devices was constructively tuned by doping ionic liquids (ILs) into the light emitting layer. The addition of ILs resulted in enhanced luminance of the devices at shorter turn-on voltages indicating its great potential for display and lighting applications.
