Solution processed OLEDs provide an attractive alternative to vacuum deposition processed OLEDs, mainly due to their significantly reduced production cost. By introducing solubilizing group (ethoxy ethane) in the ancillary ligands, we can fabricate solution processed emmiting layer without reducing physical properties. Therefore, in this study, we report the synthesis, redox, photophysical, and EL properties of soluble blue materials emitting six heteroleptic Ir(III) complexes containing the highly efficient main ligands by making use of diphenylpyridine moieties for solution processing of emitting layer in the phosphorescent OLED (PhOLED) fabrication. |
