Abstract

A material for an organic electroluminescent device having high emission efficiency and long life and an organic electroluminescent device including the same. The material for an organic electroluminescent device is represented by the following Formula 1.

First claim

What is claimed is:

1 . A material for an organic electroluminescent (EL) device represented by Formula 1:

wherein in Formula 1, X 1 is O or S;
Ar 1 and Ar 2 are each independently a substituted or unsubstituted aryl group having 6 to 30 carbon atoms for forming a ring, a silyl group, a halogen atom, a deuterium atom, a hydrogen atom, or a substituted or unsubstituted dibenzoheterole group having 10 to 30 carbon atoms for forming a ring and including an oxygen atom or a sulfur atom;
Ar 3 and Ar 4 are each independently a silyl group, or a substituted or unsubstituted aryl group having 6 to 30 carbon atoms for forming a ring;
L 1 and L 2 are each independently a direct linkage, or a divalent group selected from a silyl group and a substituted or unsubstituted arylene group having 6 to 30 carbon atoms for forming a ring;
L 3 is a divalent group selected from a silyl group and a substituted or unsubstituted arylene group having 6 to 30 carbon atoms for forming a ring;
n is an integer from 0 to 3;
m is an integer from 0 to 4; and
n+m≧1.

2 . The material for an organic EL device of claim 1 , wherein the material represented by Formula 1 is a compound represented by Formula 2 or Formula 3:

wherein in Formula 2 and 3, X 2 is O or S;
Ar 5 and Ar 6 are each independently a substituted or unsubstituted aryl group having 6 to 30 carbon atoms for forming a ring, a silyl group, a halogen atom, a deuterium atom, a hydrogen atom, or a substituted or unsubstituted dibenzoheterole group having 10 to 30 carbon atoms for forming a ring and including an oxygen atom or a sulfur atom;
Ar 7 and Ar 8 are each independently a silyl group, or a substituted or unsubstituted aryl group having 6 to 30 carbon atoms for forming a ring;
L 4 and L 5 are each independently a direct linkage, or a divalent group selected from a silyl group and a substituted or unsubstituted arylene group having 6 to 30 carbon atoms for forming a ring;
L 6 is a direct linkage or a divalent group selected from a substituted or unsubstituted aryl group having 6 to 24 carbon atoms for forming a ring and a silyl group;
R 1 to R 5 are each independently an aryl group having 6 to 30 carbon atoms for forming a ring, a heteroaryl group having 5 to 30 carbon atoms for forming a ring, an alkyl group having 1 to 15 carbon atoms, a silyl group, a halogen atom, a hydrogen atom or a deuterium atom;
n is an integer from 0 to 3;
m is an integer from 0 to 4; and
n+m≧1.

3 . The material for an organic EL device of claim 2 , wherein the compound represented by Formula 2 is a compound represented by Formula 4:

4 . The material for an organic EL device of claim 2 , wherein the compound represented by Formula 3 is a compound represented by Formula 6:

5 . The material for an organic EL device of claim 4 , wherein the compound represented by Formula 6 is a compound represented by Formula 7:

6 . The material for an organic EL device of claim 1 , wherein the material including at least one of compounds in Compounds group 1:

7 . An organic electroluminescent (EL) device, comprising a material for an organic EL device in at least one layer of a plurality of stacking layers between an emission layer and an anode, wherein the material for the organic EL device is represented
