Abstract:
An OLED device comprises a cathode, an anode, and has therebetween a light-emitting layer containing a phosphorescent emitter and a host comprising a first aluminum or gallium complex containing at least one 2-(2-hydroxyphenyl)pyridine ligand and at least one phenoxy ligand, wherein the phenoxy ligand is substituted by an amine or there is further present adjacent to the light-emitting layer on the cathode side a layer containing a second aluminum or gallium complex containing at least one 2-(2-hydroxyphenyl)pyridine ligand and at least one phenoxy ligand.
