A compound and an organic optoelectronic device are provided. The compound has the chemical formula (I): AB] n chemical formula (I). In the chemical formula (I): n denotes a positive integer and 1≦n≦5; a chemical group B has the following chemical formula (II): n n n n n n n n n n and a chemical group A has the following chemical formula (III) or (IV): n n n n n n n n n n In the chemical formula (II): R 1 to R 8 are independently selected from hydrogen, deuterium, C 1 to C 30 alkyl, C 1 to C 30 heteroatom-substituted alkyl, C 6 to C 30 aryl, and C 2 to C 30 heteroaryl. Y is selected from O, S, substituted or unsubstituted imino, substituted or unsubstituted methylene, and substituted or unsubstituted silylene, and a substituent is selected from hydrogen, deuterium, C 1 to C 30 alkyl, C 1 to C 30 heteroatom-substituted alkyl, C 6 to C 30 aryl, and C 2 to C 30 heteroaryl. Ar is selected from C 6 to C 30 aryl, and C 2 to C 30 heteroaryl. |
