First claim
Opening claim text (preview).
What is claimed is: 1. A condensed cyclic compound selected from Compounds 1 to 80 and 82 to 280 2. An organic light-emitting device comprising: a first electrode; a second electrode; and an organic layer between the first electrode and the second electrode and comprising an emission layer and at least one condensed cyclic compound of claim 1 . 3. The organic light-emitting device of claim 2 , wherein the emission layer comprises a host and a dopant, the host comprises the at least one condensed cyclic compound, and the dopant comprises a phosphorescent dopant. 4. The organic light-emitting device of claim 2 , wherein the emission layer emits blue light. 5. An electronic device comprising the organic light-emitting device of claim 2 . 6. The condensed cyclic compound of claim 1 selected from Compounds 82 to 120. 7. An organic light-emitting device comprising: a first electrode; a second electrode; and an organic layer between the first electrode and the second electrode and comprising an emission layer and at least one condensed cyclic compound of claim 6 and the emission layer emits blue light.
