一种通式化合物及有机发光器件
摘要：
本发明涉及一种下式表示的通式化合物：式(I)中：A4选自氰基或苯氰基；A1、A2和A3分别独立由下式(II)或式(III)表示：式(II)和式(III)中：R1-R8和R9-R16分别独立选自氢、C1～C10的烷基、C6～C30的取代或未取代的芳基或稠环芳烃基团、C3～C30的取代或未取代的杂芳基或稠杂环芳烃基团；且R1-R8中任何相邻的两个任选地接成环状结构，R9-R16中任何相邻的两个任选地接成环状结构；且当A1选自式(II)时，式(Ⅱ)中的R1和R8中至少一个为氢；当A1选自式(III)时，式(Ⅲ)中的R9和R16中至少一个为氢；式(III)中：X选自氧、硫、亚氨基、亚甲基、亚甲硅烷基中。本发明还涉及采用上述通式化合物的有机电致发光器件。
摘要（英）：

The present invention relates to a compound represented by the formula (I) shown in the specification. In the formula (I), A4 is selected from cyano or benzene cyano. A1, A2 and A3 are each independently represented by the formula (II) or (III) shown in the specification. In the formula (II) and formula (III), R1-R8 and R9-R16 are each independently selected from hydrogen, a C1-C10 alkyl group, asubstituted or unsubstituted C6-C30 aryl or fused ring aromatic hydrocarbon group, a substituted or unsubstituted C3-C30 heteroaryl or fused heterocyclic aromatic hydrocarbon group; and any adjacent two of the R1-R8 are optionally joined to a cyclic structure, any adjacent two of the R9-R16 are optionally joined to a cyclic structure; and when A1 is selected from the formula (II), at least one ofR1 to R8 in the formula (II) is hydrogen; when the A1 is selected from the formula (III), at least one of R9 to R16 in the formula (III) is hydrogen; in the formula (III), X is selected from the groupconsisting of oxygen, sulfur, imino, methylene, and silicylene. The invention further relates to an organic electroluminescent device employing the compound of the formula (I).
