Abstract: Novel ligands for metal complexes that are useful as phosphorescent emitters in OLEDs are disclosed. The ligands contain an aryl covalently bonded to the coordinating metal where the aryl group has at least two different alkyl side chains that are linked ortho and para compared to the linkage of the coordinating metal on that aryl group.
