First claim
Opening claim text (preview).
The invention claimed is: 1. A compound for an organic optoelectronic device, the compound being represented by Chemical Formula 1: wherein, in Chemical Formula 1, R 1 is a phenyl group that is unsubstituted or substituted with a C6 to C12 aryl group, a biphenyl group that is unsubstituted or substituted with a C6 to C12 aryl group, a fluorenyl group that is unsubstituted or substituted with a C6 to C12 aryl group, a dibenzofuranyl group that is unsubstituted or substituted with a C6 to C12 aryl group or a dibenzothiophenyl group that is unsubstituted or substituted with a C6 to C12 aryl group, R 2 to R 9 are each independently hydrogen, deuterium, a cyano group, a halogen, a substituted or unsubstituted amine group, a substituted or unsubstituted C1 to C30 alkyl group, a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C2 to C30 heterocyclic group, or a combination thereof, and Ar 1 and Ar 2 are each independently hydrogen, deuterium, or a substituted or unsubstituted C6 to C20 aryl group. 2. The compound of claim 1 , wherein R 1 is a group of Group I: wherein, in Group I, * is a linking point. 3. The compound of claim 1 , wherein R 2 to R 5 are each independently hydrogen, deuterium, or a substituted or unsubstituted C6 to C12 aryl group. 4. The compound of claim 1 , wherein R 6 to R 9 are each independently hydrogen, deuterium, or a substituted or unsubstituted C6 to C12 aryl group. 5. The compound of claim 1 , wherein Ar 1 and Ar 2 are each independently hydrogen, deuterium, or a substituted or unsubstituted C6 to C12 aryl group. 6. The compound of claim 1 , wherein the compound is a compound of Group 1: 7. An organic optoelectronic device, comprising: an anode and a cathode facing each other, at least one organic layer disposed between the anode and the cathode, wherein the at least one organic layer comprises the compound for the organic optoelectronic device of claim 1 . 8. The organic optoelectronic device of claim 7 , wherein the at least one organic layer comprises a light emitting layer, and the light emitting layer comprises the compound for an organic optoelectronic device. 9. A display device comprising the organic optoelectronic device of claim 7 .
