Patent ID: 8877356

Claim:
An OLED device comprising an anode, a cathode and a yellow light-emitting layer located therebetween, the light-emitting layer comprising: (a) a 9,10-diarylanthracene host represented by: wherein: R 1 and R 6 each independently represents an aryl group having 6-24 carbon atoms; R 3 and R 8 are each independently chosen from hydrogen, alkyl groups from 1-24 carbon atoms or aromatic groups from 5-24 carbon atoms; R 2 , R 4 , R 5 , R 7 , R 9 and R 10 are hydrogen; (b) a yellow light-emitting tetraceneTD-8: and (c) a non-light-emitting diarylamine substituted 9,10-diarylsubstituted anthracene according to Formula (3): wherein: X 1 and X 2 are independently selected aryl groups of 6 to 30 nucleus carbon atoms; Ar 3 and Ar 4 each independently represents a substituted or unsubstituted aryl group of 6 to 30 nucleus carbon atoms where Ar 1 and Ar 2 or Ar 3 and Ar 4 can optionally be joined together; and n is 2.
