Abstract:
An OLED including an organic layer that contains metal complex compounds that are useful as a phosphorescent emitter is disclosed. The metal complex compounds include ligands that incorporate fluorinated side chains and has at least one substituent R selected from the group consisting of partially fluorinated alkyl, partially fluorinated cycloalkyl, and combinations thereof, wherein R is directly bonded to an aromatic ring, In the compound, C having an F attached thereto is separated by at least one carbon atom from the aromatic ring.
