ABSTRACT:
A red organic light-emitting compound which has a superior heat-resistance and is capable of adjusting the color of the emitted light, and an organic light-emitting device including the same are disclosed. The organic light-emitting compound has the structure of the following chemical formula, and the organic light-emitting device includes the first electrode having a high work function; the second electrode having a low work function; and at least one organic layer formed between the first electrode and the second electrode, which includes the red organic light-emitting compound, wherein, X is C, O, S, SO2or N; Y is S or —CR11═CR12—; R1, R2, R3, R11and R12can be the same or different, and are hydrogen, alkyl group of 1 to 20 carbon atoms, alkoxy group of 1 to 5 carbon atoms, aryl or heteroaryl group of 4 to 24 carbon atoms, heterocyclic group of 4 to 6 carbon atoms, or fused ring group of 4 to 24 carbon atoms; R4and R5can be the same or different, and are the functional group defined for R1or O; when R4and R5are O. R4and R5can be connected to form a heterociclyc ring; is the functional group defined for R1or amine group; and n is 1, 2 or 3.
