Summary: | 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.
L'invention concerne un dispositif à OLED comprenant une cathode, une anode, entre lesquelles se situe une couche émettant de la lumière comprenant (a) un composé de 2-arylanthracène et (b) un second composé d'anthracène émettant de la lumière dont deux positions présentent une substitution d'un acide aminé, au moins une amine étant substituée au niveau de la position 2 du second composé d'anthracène. |
