Novel phosphorescent tetradentate platinum compounds of Formula I are provided. The complexes contain a dibenzo moiety, which allows for the creation of OLED devices with improved properties when compounds of Formula I are incorporated into such devices. Compounds of Formula I′ that 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.
提供了公式I的新型荧光四齿配位铂化合物。这些配合物包含一个二苯并基团,当I式化合物被纳入OLED器件中时,可以改善器件性能。I'式化合物包括两个配体,其中一个包含一个扭曲芳基团连接到N-1的咪唑环,另一个芳香环通过碳原子连接到铂上,并含有一个5元环碳环或杂环。这些化合物可以优势地用于OLED器件中。
