The invention relates to organic electroluminescent materials and devices. 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. 本申请涉及有机电致发光材料和装置。公开了可在OLED中用作磷光发射体的金属络合物的新颖配体。所述配体含有共价键结到配位金属的芳基，其中所述芳基具有至少两个不同的烷基侧链，所述烷基侧链相较于在所述芳基上所述配位金属的键联是邻位和对位连接。
