Abstract
A polycyclic compound according to an embodiment of the inventive concept is represented by the following Formula 1: In Formula 1, Ar1 and Ar2 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 Ar1 and Ar2 may combine with each other to form a ring, and A is represented by the following Formula 2-1 or 2-2:
Claims20
A polycyclic compound represented by the following Formula 1:
- in Formula 1,
- Ar1 and Ar2 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 Ar1 and Ar2 optionally combine with each other to form a ring, and
- A is represented by the following Formula 2-1 or 2-2:
- in Formula 2-1,
- R1 to R12 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 2-2,
- 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.
