Abstract
A new class of luminescent iridium(III) complexes, luminescent material and organic electroluminescent device thereof had been disclosed. The novel luminescent iridium(III) complexes comprises the formula [(C N).sub.2Ir(P O)] with 2-(diphenylphosphino)phenolate as the ancillary chelate. The iridium complexes of the present invention can be used as the red, blue or green-emitting dopants. These luminescent materials can be applied in the fabrication of light-emitting layer of organic electroluminescent devices and providing the high efficiently red, blue or green light organic electroluminescent devices of commercial pursuits.
