Abstract
An OLED device comprises a cathode, an anode, and has 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 a minimum of two positions, wherein at least one amine is substituted at the 2 position of the second anthracene compound.
Claims9
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 represented by:
- and
- (b) a light-emitting second anthracene compound, the light-emitting second anthracene compound being an N,N,N′,N′,9,10-hexaaryl-2,6-anthracenediamine compound,
- wherein:
- d1, d3-d5, d7, and d8 are hydrogen;
- d6 is an aryl group;
- each g is the same or different and each represents an independently selected substituent, provided that two substituents may combine to form a ring group;
- p, r, and s are independently 0-5, and
- the selected substituent is a C4-C30 aryl group.
