What is claimed is: 1. A compound having a structure represented by General Formula (G1), wherein: Ar 1 and Ar 2 each independently represent a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, R 1 to R 11 each independently represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, A represents a substituent represented by General Formula (S1) or General Formula (S2), X represents oxygen or sulfur, and R 12 to R 18 each independently represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 13 carbon atoms. 2. The compound according to claim 1 , wherein Ar 1 and Ar 2 each independently represents an unsubstituted aryl group having 6 to 13 carbon atoms. 3. The compound according to claim 1 , wherein R 1 to R 11 each independently represent a hydrogen atom. 4. The compound according to claim 1 , wherein R 12 to R 18 each independently represent a hydrogen atom. 5. The compound according to claim 1 , wherein the compound comprises a structure represented by General Formula (G2-1), 6. The compound according to claim 5 , wherein Ar 1 and Ar 2 each independently represents an unsubstituted aryl group having 6 to 13 carbon atoms. 7. The compound according to claim 5 , wherein R 1 to R 11 each independently represent a hydrogen atom. 8. The compound according to claim 5 , wherein R 12 to R 18 each independently represent a hydrogen atom.
