Abstract

An organic compound, and an organic light emitting diode and an organic light emitting device including the same are disclosed. For example, an organic compound is represented by the following chemical formula. The organic light emitting diode and the organic light emitting device each includes the organic compound.

First claim

What is claimed is:

1 . An organic compound represented by Formula 1:

wherein a1 is an integer of 0 to 5, a2 is an integer of 0 to 3,
wherein each R 1 is independently selected from the group consisting of a substituted or unsubstituted C1 to C10 alkyl group,
wherein each R 2 is independently selected from the group consisting of a substituted or unsubstituted C1 to C10 alkyl group, a substituted or unsubstituted C6 to C60 aryl group and a substituted or unsubstituted C3 to C60 heteroaryl group,
wherein when a1 is 2 or more, 2 or more R 1 groups are the same or different,
wherein when a2 is 2 or more, 2 or more R 2 groups are the same or different,
wherein each L 1 , L 2 and L 3 is independently selected from the group consisting of a single bond, a substituted or unsubstituted C6 to C60 arylene group and a substituted or unsubstituted C3 to C60 heteroarylene group,
wherein Ar 1 is selected from Formula 1a-1 to Formula 1a-5:

wherein in Formula 1a-1, b1 is an integer of 0 to 5,
wherein in Formula 1a-2, b2 is an integer of 0 to 7,
wherein in each of Formulas 1a-3 to 1a-5, each b3 is independently an integer of 0 to 4,
wherein when each b1, b2, and b3 is 2 or more, 2 or more R 3 groups are the same or different,
wherein in Formula 1a-4, V 1 is selected from O, S, and C(R 3 ) 2 ,
wherein in Formula 1a-5, V 2 is selected from O and S,
wherein in each of Formulas 1a-1 to 1a-5, each R 3 is independently selected from the group consisting of deuterium, a substituted or unsubstituted C1 to C10 alkyl group, a substituted or unsubstituted C6 to C60 aryl group and a substituted or unsubstituted C3 to C60 heteroaryl group,
wherein Ar 2 is selected from Formula 1b-1 and Formula 1b-2,

wherein in each of Formulas 1b-1 and 1b-2, b4 is an integer of 0 to 4,
wherein each R 4 is independently selected from the group consisting of deuterium, a substituted or unsubstituted C1 to C10 alkyl group, a substituted or unsubstituted C6 to C60 aryl group and a substituted or unsubstituted C3 to C60 heteroaryl group,
wherein when b4 is 2 or more, 2 or more R 4 groups are the same or different, and
wherein in Formula 1b-2, R 5 is selected from the group consisting of hydrogen, deuterium, a substituted or unsubstituted C1 to C10 alkyl group and a substituted or unsubstituted C6 to C60 aryl group.

2 . The organic compound according to claim 1 , wherein Ar 1 and Ar 2 are different.

3 . The organic compound according to claim 1 , wherein Formula 1 is represented by Formula 1-5 or Formula 1-6:

4 . The organic compound according to claim 1 , wherein the organic compound is one of the compounds in Formula 2:

5 . An organic light emitting device, comprising:
a substrate; and an organic light emitting diode positioned on the substrate and including:
a first electrode;
a second electrode facing the first electrode; and
a first emitting part between the first electrode and the second electrode, the first emitting part including a first emitting material layer,
wherein the first emitting material layer includes a first compound that is the organic compound of claim 1 .

6 . The organic light emitting device according to claim 5 , wherein the first emitting material layer further includes a second compound represented by Formula 3:

wherein each c1 and c4 is indepe
