Organometallic compounds comprising phenylquinoline or phenylisoquinoline ligands having quinoline or isoquinoline attached via two carbon atoms to the benzene ring of phenylquinoline or phenylisoquinoline, respectively quinoline. These compounds also contain substituents other than hydrogen and deuterium on the quinoline, isoquinoline or linker. These compounds can be used as red emitters in phosphorescent OLEDs. In particular, these compounds can provide stable, narrow and efficient red emission. |
