摘要：
Novel cyclometallated tetradentate Pt(II) compounds are provided. The compounds comprise two ligands that contain a 5-membered carbocyclic or heterocyclic ring, one of which contains an imidazole ring with a twisted aryl group attached to N-1 and a second aromatic ring that is attached to the platinum via a carbon atom. These compounds may be advantageously used in OLEDs.
