More Information
Summary:An OLED device comprises a cathode and anode and having therebetween a light-emitting layer, wherein there is located between the cathode and the light-emitting layer a further layer, not contiguous to the light-emitting layer, containing a metal complex of 3 bidentate ligands having Formula (1): wherein: each Za and each Zb is independently selected and each represents the atoms necessary to complete an unsaturated ring; Za and Zb are directly bonded to one another provided Za and Zb may be further linked together to form a fused ring system; and wherein the further layer also comprises an alkali metal material. Materials of the invention provide offer good luminance and reduced drive voltage.
