Abstract
Iridium complexes with ligands containing twisted aryl groups having extended conjugation (i.e., the twisted aryl is substituted with an additional aryl group) and organic light emitting devices including the same are disclosed. The iridium complexes can be used in organic light emitting devices may provide improved stability color, lifetime and manufacturing.
