Light-Emitting Electrochemical Cells Based on Phosphorescent Iridium Complex Incorporated with Ionic Liquids |
| 초록 |
A heteroleptic phosphorescent iridium complex [Ir(ppz)2(dmphen)]PF6, containing 1-phenylpyrazole (ppz) as cyclometalated ligand and 5,6-dimethyl-1,10-phenanthroline (dmphen) as ancillary ligand, has been synthesized and its photophysical and electrochemical properties have been investigated. Light-emitting electrochemical cells (LECs) based on this complex were fabricated using air stable electrodes resulting in a yellowish light emission. Furthermore, three different imidazolium based ionic liquids (ILs) such as 1-butyl-3-methylimidazolium hexafluorophosphate (BMIMPF6), 1-ethyl-3-methylimidazolium hexafluorophosphate (EMIMPF6) and 1-hexyl-3-methylimidazolium hexafluorophosphate (HMIMPF6) were incorporated into the active layer and hence the luminance and the current density of the devices were found to be enhanced with increasing ionic conductivities of ILs. |
