First claim
Opening claim text (preview).
What is claimed is: 1. A compound for an organic fight emitting device, the compound represented by Chemical Formula 1: wherein, Ar is a substituted or unsubstituted C6 to C20 arylene group, a substituted or unsubstituted C2 to C20 heteroarylene group, or a combination thereof, and L is a single bond, a substituted or unsubstituted C6 to C10 arylene group, or a combination thereof. 2. The compound of claim 1 , wherein the C6 to C20 arylene group comprises a phenylene group, a naphthylene group, a biphenylene group, a terphenylene group, a phenanthrenylene group, or a combination thereof. 3. The compound of claim 1 , wherein the C2 to C20 heteroarylene group comprises a nitrogen atom (N) as a ring atom. 4. The compound of claim 3 , wherein the C2 to C20 heteroarylene group comprises a pyridine group, a quinoline group, or a combination thereof. 5. An organic light emitting device comprising a first electrode, a second electrode facing the first electrode, and an organic layer between the first electrode and the second electrode, wherein the organic layer comprises a compound represented by Chemical Formula 1: wherein, Ar is a substituted or unsubstituted C6 to C20 arylene group, a substituted or unsubstituted C2 to C20 heteroarylene group, or a combination thereof, and L is a single bond, a substituted or unsubstituted C6 to C10 arylene group, or a combination thereof. 6. The organic light emitting device of claim 5 , wherein the C6 to C20 arylene group comprises a phenylene group, a naphthylene group, a biphenylene group, a terphenylene group, a fluorenylene group, or a combination thereof. 7. The organic light emitting device of claim 5 , wherein the C2 to C20 heteroarylene group comprises a nitrogen atom (N) as a ring atom. 8. The organic light emitting device of claim 7 , wherein the C2 to C20 heteroarylene group comprises a pyridine group, a quinoline group, or a combination thereof. 9. The organic light emitting device of claim 5 , wherein the organic layer comprises a single layer or a plurality of layers. 10. The organic light emitting device of claim 5 , wherein the organic layer comprises a hole transport layer. 11. The organic light emitting device of claim 10 , wherein the organic layer further comprises an electron transport layer.
