摘要：
Phosphorescent materials and devices having high efficiency and stability, narrow spectrum, and improved processibility. In particular, iridium complexes containing acac-derived ligands with branched alkyl substituents with branching at a position further than the α position to the carbonyl group, were found to be suitable for use as emitters in OLED devices.
