Abstract

The present specification relates to a compound represented by Chemical Formula 1, a coating composition comprising the compound represented by Chemical Formula 1, an organic light emitting device using the same, and a method for manufacturing the same.

First claim

The invention claimed is:

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

wherein, in Chemical Formula 1,
L and L1 to L4 are the same as or different from each other, and each independently a substituted or unsubstituted arylene group;
Ar1 and Ar2 are the same as or different from each other, and each independently a substituted or unsubstituted aryl group; or a substituted or unsubstituted heteroaryl group;
R1 to R4 are the same as or different from each other, and each independently hydrogen; deuterium; a substituted or unsubstituted alkyl group; a substituted or unsubstituted alkoxy group; a substituted or unsubstituted aryl group; or a substituted or unsubstituted heteroaryl group;
Y1 to Y4 are the same as or different from each other, and each independently —(R101)s; or —X-A, and two or more of Y1 to Y4 are —X-A;
R101 is hydrogen; deuterium; a halogen group; a substituted or unsubstituted alkyl group; a substituted or unsubstituted alkoxy group; a substituted or unsubstituted aryl group; or a substituted or unsubstituted aryloxy group;
s is an integer of 0 to 5, and when s is 2 or greater, two or more R101 s are the same as or different from each other;
X is O or S;
A is a functional group crosslinkable by heat or light;
n1 and n4 are each an integer of 0 to 4;
n2 and n3 are each an integer of 0 to 3; and
when n1 to n4 are each 2 or greater, R1s, R2s, R3s and R4s are the same as or different from each other.

2. The compound of claim 1 , wherein the functional group crosslinkable by heat or light is any one of the following structures:

wherein,
T1 is hydrogen; or a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms; and
T2 to T4 are the same as or different from each other, and each independently a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms.

3. The compound of claim 1 , wherein Chemical Formula 1 is represented by any one of the following Chemical Formulae 2 to 5:

wherein, in Chemical Formulae 2 to 5,
R1 to R4, n1 to n4, Ar1, Ar2 and L have the same definitions as in Chemical Formula 1;
X1 to X4 are the same as or different from each other, and each independently O or S;
A1 to A4 are the same as or different from each other, and each independently a functional group crosslinkable by heat or light;
R21 to R26 are the same as or different from each other, and each independently hydrogen; deuterium; a halogen group; a substituted or unsubstituted alkyl group; a substituted or unsubstituted alkoxy group; a substituted or unsubstituted aryloxy group; a substituted or unsubstituted aryl group; or a substituted or unsubstituted heteroaryl group;
p1 and p2 are each an integer of 0 to 5;
p3 and p4 are each an integer of 0 to 4;
p5 and p6 are each an integer of 0 to 7; and
when p1 to p6 are each 2 or greater, R21s, R22s, R23s, R24s, R25s and R26s are the same as or different from each other.

4. The compound of claim 1 , wherein L is the following Chemical Formula 1-A or 1-B:

wherein, in Chemical Formulae 1-A and 1-B,
R11 to R13 are the same as or different from each other, and each independently hydrogen;
deuterium; a substituted or unsubstituted alkyl group; a substituted or unsubstituted alkoxy group; a substituted or unsubstituted aryl group; or a substituted or unsubstituted heteroaryl group;
m1 to m3 are each an integer of 0 to 4; and
when m1 to m3 are 2 or greater, R11s, R12s and R13s are the same as or different from each other.

5. The compound of claim 1 , wherein Chemical Formula 1 is represented by any one of the following Compounds 1 to 140:
