Performance Improvement by Introducing Bulky Substituents to Solution-processable Phosphorescent Materials

摘要

New emitting materials especially designed for solution processing were synthesized, and their OLED device characteristics were investigated. By introducing bulky substituents, the new emitting materials showed improved OLED device performances compared with non-substituted one. Moreover we also fabricated ink-jet printed OLEDs using our newly synthesized emitting materials.
