Beta-diketone ancillary ligands and their metal complexes used in organic optoelectronic devices

摘要

The present invention discloses a phosphor material for organic optoelectronic devices. The phosphor is a complex comprising a metal (Ir or Pt) and an aryl-modified beta-diketone ligand. The complexes of this invention are useful to function as an emitter in the emissive layer of an organic light emitting diode, even as the complex is the main component of this layer.
