Abstract

This invention provides a systematic method for syntheses of new electroluminescent iridium metal complexes by introducing chelating ligands such as quinoxaline, quinazoline, and pyrimidine. For utilization of quinoxaline, quinazoline or pyrimidine ligands, the strategy of substituting the carbon atom with the highly electronegative nitrogen atom or extending the delocalization of π electrons on the chelating aromatic chromophores can not only enhance the rigidity of the ligands and suppress the non-radiative decay, but also alter the electronic structures of the coordinating ligands. As a result, the energy gaps between the HOMO and LUMO orbitals, i.e. the energy gaps of IL(ππ*) or MLCT transitions are significantly reduced, shifting the emission wavelengths to the region of saturated red color. These phosphorescent complexes can be used as the emitting or emitter dopant materials to fabricate the high efficiency OLEDs for various types of future, flat panel display applications.
