The invention relates to an organical electroluminescent material and a device thereof. Novel ligands for metal complexes that are useful as phosphorescent emitters in OLEDs are disclosed. The ligandscontain 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. 本申请涉及有机电致发光材料和装置。公开了适用作OLED中的磷光发射体的金属络合物的配体。所述配体含有共价键结到配位金属的芳基。所述芳基具有对位连接到所述芳基上的所述配位金属键的环烷基或被取代的环烷基。
