| Outline of Final Research Achievements |
Aimed at development of solution-processable high-performance organic light-emitting diodes (OLEDs) with innovative device structures, we here prepared novel organometallic phosphorescent materials with carrier-transporting ability. Employing cyclometalated ligands with pi-extended conjugation systems and carrier-transporting dendrons, we successfully obtained phosphorescent organoplatinum(II) and organoiridium(III) complexes which are applicable to the emission layers in OLEDs. Using the developed hybrid phosphorescent materials as a single emission layer, solution-processed OLEDs were successfully fabricated. Furthermore, doping a red phosphorescent material into the emitting layer, white-emitting device was also obtained.
