Abstract

The present disclosure provides an organic compound of the following formula and an organic light emitting diode and an OLED device including the same.

First claim

What is claimed is:

1. An organic compound represented by the following Formula 1:

wherein:
each of X 1 , X 2 and X 3 is independently selected from carbon (C) and nitrogen (N), provided that at least one of X 1 to X 3 is N, and
each of Z 1 , Z 2 and Z 3 is independently selected from a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C5 to C30 heteroaryl group, a substituted or unsubstituted C1 to C12 alkyl group, a substituted or unsubstituted C1 to C12 alkoxy group, a substituted or unsubstituted C1 to C12 ether group, halogen, cyano (CN), trimethylsilyl, Formula 2, Formula 3 and Formula 4, provided that at least one of Z 1 to Z 3 is represented by one of the following Formulas 2 to 4,

wherein in Formula 2,
each of X 11 and X 12 is independently selected from C and N, provided that at least one of X 11 and X 12 is N,
each of X 13 to X 16 is independently selected from C and N,
R 1 is selected from a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C5 to C30 heteroaryl group, a substituted or unsubstituted C1 to C12 alkyl group, a substituted or unsubstituted C1 to C12 alkoxy group, cyano, halogen and trifluoromethyl, and
m1 is an integer of 0 to 4,
wherein in Formula 3,
each of X 21 and X 22 is independently selected from C and N, provided that at least one of X 21 and X 22 is N,
R 2 is selected from cyano and phenyl,
R 3 is selected from a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C5 to C30 heteroaryl group, a substituted or unsubstituted C1 to C12 alkyl group, a substituted or unsubstituted C1 to C12 alkoxy group, cyano, halogen and trifluoromethyl, and m2 is an integer of 0 to 3,
wherein in Formula 4,
each of X 31 and X 32 is independently selected from N and oxygen (O), provided that when one of X 31 and X 32 is N, then the other one of X 31 and X 32 is O,
each of X 33 to X 36 is independently selected from C and N,
R 4 is selected from a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C5 to C30 heteroaryl group, a substituted or unsubstituted C1 to C12 alkyl group, a substituted or unsubstituted C1 to C12 alkoxy group, cyano, halogen and trifluoromethyl, and
m3 is an integer of 0 to 4.

2. The organic compound of claim 1 , wherein at least one of X 13 to X 16 is C, and R 1 is selected from methyl, trifluoromethyl, trifluoromethoxy, cyano and fluorine (F).

3. The organic compound of to claim 1 , wherein R 2 is phenyl substituted by at least one of F and CN, and R 3 is CN.

4. The organic compound of claim 1 , wherein at least one of X 33 to X 36 is C, and R 4 is selected from F, CN and trifluoromethyl.

5. The organic compound of claim 1 , wherein the organic compound has one of the following structures:
