Abstract
Metal complexes containing azabenzothiazole are disclosed, which comprise a new series of ligands containing azabenzothiazole structure. The metal complexes can be used as emitters in the emissive layer of an organic electroluminescent device. The use of these novel metal complexes as emitters in OLED devices leads to more saturated color than the compounds containing benzothiazole ligands. An electroluminescent device and a formulation are also disclosed.
