Abstract

The present specification relates to a compound, a coating composition including the same, and an organic light emitting device.

First claim

The invention claimed is:

1. A compound represented by the following Chemical Formula 1:

wherein, in Chemical Formula 1,
Ar1 and Ar2 are the same as or different from each other, and each independently a substituted or unsubstituted aryl group;
R1 to R4 are the same as or different from each other, and each independently hydrogen; deuterium; a halogen group; a nitrile group; a substituted or unsubstituted alkyl group; a substituted or unsubstituted aryl group; or a substituted or unsubstituted heterocyclic group;
r1 to r3 are the same as or different from each other, and each independently from 1 to 3;
r4 is from 1 to 4;
when r1 to r4 are each 2 or greater, the two or more R1 to R4 are each the same as or different from each other;
X3 is

X1 and X2 are the same as or different from each other, and each independently

each

means a linking site;
L4 is a substituted or unsubstituted alkylene group;
L5 is a direct bond; or a substituted or unsubstituted arylene group;
R5 and R6 are the same as or different from each other, and each independently a substituted or unsubstituted alkyl group;
a1 and a2 are the same as or different from each other, and each independently 0 or 1;
when a2 is 0, L2 is a substituted or unsubstituted aryl group;
when a2 is 1, L2 is a direct bond; or a substituted or unsubstituted arylene group;
L1 is a substituted or unsubstituted arylene group; or a substituted or unsubstituted heteroarylene group;
m is 1 or 2, and when m is 2, L1 s are the same as or different from each other;
L3 is a direct bond; or a substituted or unsubstituted alkylene group; and
0≤a1+a2≤2.

2. The compound of claim 1 , wherein Chemical Formula 1 is represented by the following Chemical Formula 2:

in Chemical Formula 2,
L1 to L3, Ar1, Ar2, R1 to R4, r1 to r4, X1 to X3, m, a1 and a2 have the same definitions as in Chemical Formula 1.

3. The compound of claim 1 , wherein L1 is a substituted or unsubstituted phenylene group; a substituted or unsubstituted divalent fluorene group; or a substituted or unsubstituted divalent dibenzothiophene group.

4. The compound of claim 1 , wherein Ar1 and Ar2 are the same as or different from each other, and each independently a substituted or unsubstituted phenyl group, or a substituted or unsubstituted biphenyl group.

5. The compound of claim 1 , wherein the compound represented by Chemical Formula 1 is any one selected from among the following compounds:
