Abstract
An OLED device comprising a cathode, an anode, and having located therebetween a light emitting layer containing an emitting compound having formula (I): (piq)b M ppy (I) wherein piq is a phenylisoquinoline group and ppy is a phenylpyridine group bearing at least one further substituent on the pyridine ring, wherein M is Ir, Rh, Pt, or Pd and b is 2 in the case of Ir and Rh and 1 in the case of Pt and Pd.
