DOPANT COMPOSITION HAVING PHOSPHORESCENT CHARACTERISTIC AT ROOM TEMPERATURE AND PHOSPHORESCENT ORGANIC LIGHT EMITTING DEVICE INCLUDING THE LIGHT-EMITTING COMPOSITION

摘要

In a dopant composition having a room temperature phosphorescent characteristic of the present invention and an organic light emitting device comprising the same, the dopant composition includes a main dopant represented by chemical formula 1 and an auxiliary dopant represented by chemical formula 2. R_1 to R_8 and R_a to R_j are each independently a halogen atom, hydrogen, deuterium, an alkyl group having 1-60 carbon atoms, an alkenyl group having 2 to 60 carbon atoms, an alkynyl group having 2 to 60 carbon atoms, an aryl group having 6 to 60 carbon atoms, a heteroaryl group having 3 to 60 carbon atoms, an alkoxy group having 1 to 60 carbon atoms, and so on.
