1. An OLED device comprising a cathode, an anode, and having therebetween a light-emitting layer, wherein the light-emitting layer comprises:
(a) a 2-arylanthracene compound and (b) a light-emitting second anthracene compound having amino substitution at the 2,6-positions, represented by Formula [5]: wherein:
d1, d3-d5 and d7-d8 each represent hydrogen;substituents A9 and A16 are phenyl rings;substituents R2 and R6 independently represent hydrogen or an alkyl group comprising from 1 to 10 carbon atoms;m and n are independently 1;substituents G9 and G10 are independently substituted or unsubstituted phenyl rings;substituent G9 is joined together with substituent A9 to form an additional fused ring group; andsubstituent G9 is joined together with substituent A16 to form an additional fused ring group.
