Abstract

A polycyclic compound according to an embodiment of the inventive concept is represented by the following Formula 1:

In Formula 1, Ar 1 and Ar 2 are each independently substituted or unsubstituted aryl group having 6 to 30 carbon atoms for forming a ring, or substituted or unsubstituted heteroaryl group having 2 to 30 carbon atoms for forming a ring, where Ar 1 and Ar 2 may combine with each other to form a ring, and A is represented by the following Formula 2-1 or 2-2:

First claim

What is claimed is:

1. A polycyclic compound represented by the following Formula 1, Formula 3, or Compound 41:

in Formula 1,
Ar 1 and Ar 2 are each independently selected from substituted or unsubstituted anthracenyl group, substituted or unsubstituted pyrenyl group, substituted or unsubstituted phenanthryl group, substituted or unsubstituted chrysenyl group, substituted or unsubstituted triphenylenyl group, and substituted or unsubstituted carbazolyl group, where Ar 1 and Ar 2 optionally combine with each other to form a ring, and
A is represented by the following Formula 2-1:

in Formula 2-1,
R 1 to R 12 are each independently selected from hydrogen, deuterium, halogen, silyl group, substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, substituted or unsubstituted arylamine group, substituted or unsubstituted aryl group having 6 to 30 carbon atoms for forming a ring, and substituted or unsubstituted heteroaryl group having 2 to 30 carbon atoms for forming a ring, where adjacent groups optionally combine with each other to form a ring,
in Formula 3,
W is selected from hydrogen, deuterium, halogen, silyl group, substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, substituted or unsubstituted aryl group having 6 to 60 carbon atoms for forming a ring, and substituted or unsubstituted heteroaryl group having 5 to 60 carbon atoms for forming a ring, and
p is an integer from 0 to 8, wherein when p is 2 or more, a plurality of W are the same as or different from each other,
E is O, S, or NR′,
m is 0 or 1, and
Z and R′ are each independently represented by the following Formula 4:

in Formula 4,
U 1 and U 2 are each independently substituted or unsubstituted aryl group having 6 to 30 carbon atoms for forming a ring, or substituted or unsubstituted heteroaryl group having 2 to 30 carbon atoms for forming a ring,
L′ is substituted or unsubstituted arylene group having 6 to 30 carbon atoms for forming a ring, and
n is 0 or 1,
wherein when E is NR′, m is 0, and when E is O or S, m is 1.

2. The polycyclic compound of claim 1 , wherein Formula 3 is represented by the following Formula 5:

in Formula 5,
E, U 1 and U 2 are the same as defined in Formula 4.

3. The polycyclic compound of claim 1 , wherein the polycyclic compound represented by Formula 3 is at least one selected from Compounds A-1 to A-23 (collectively denoted as Formula Group 1):

4. A polycyclic compound represented by one of the following Formulae 9 and 11-16:

wherein in Formulae 9 and 11-16,
Cy1 and Cy2 are each independently substituted or unsubstituted heteroaryl group including 1 to 3 N atoms as heteroatoms and having 2 to 30 carbon atoms for forming a ring,
d and e are each independently 0 or 1, where the sum of d and e is not 0 (d+e≠0),
Cy3 is substituted or unsubstituted aryl group having a three- or four-membered ring,
X is O, S, NR 13 , CR 14 R 15 , or SiR 16 R 17 ,
Y is O, S, NR 20 , or substituted or unsubstituted phosphine oxide,
Ar 1 and Ar 2 are each independently substituted or unsubstituted aryl group having 6 to 30 carbon atoms for forming a ring, or substituted or unsubstituted heteroaryl group having 2 to 30 carbon atoms for forming a ring, where Ar 1 and Ar 2 optionally combine with each other to form a ring,
R 1 to R 12 and R 13 to R 17 are each independently selected from hydrogen, deuterium, halogen, silyl group, substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, substituted or unsubstituted arylamine group, substituted or unsubstituted aryl group having 6 to 30 carbon atoms for forming a ring, and substituted or unsubstituted heteroaryl group having 2 to 30 carbon atoms for forming a ring, where adjacent groups selected from R 1 to R 12 optionally combine with each other to form a ring,
wherein in Formula 13, R 3 and R 6 are each independently selected from substituted or unsubstituted arylamine group, substituted or unsubstituted aryl group having 6 to 30 carbon atoms for forming a ring, and substituted or unsubstituted heteroaryl group having 2 to 30 carbon atoms for forming a ring, and
R 18 to R 20 are each independently selected from hydrogen, deuterium, substituted or unsubstituted aryl group having 6 to 30 carbon atoms for forming a ring, and substituted or unsubstituted heteroaryl group having 2 to 30 carbon atoms for forming a ring.

5. A polycyclic compound represented by at least one selected from Compounds 1, 2, 4-8, 10 to 50, 52 to 56, 58 to 60, 62 to 66 and 67 to 122 (collectively denoted as Formula Group 2 and Formula Group 3, respectively):
