An organic compound having the following structural formula is provided:
wherein Ar
1
to Ar
5
are aromatic or heteroaromatic structural units, X, Y, and Z are bridging groups connecting two or three aromatic rings, and n is an integer between 1 and 4. The organic compound has an increased resonance factor and a reduced Δ(S1−T1), thus facilitating acquisition of thermally-excited delayed fluorescence properties provided with increased light emission efficiency, and implementing high efficiency and extended service life of an OLED component. In addition, a synthesis process for the organic compound is simple and inexpensive. A mixture a formulation and an organic electronic device containing the organic compound are also provided.
提供具有以下结构式的有机化合物:其中Ar1至Ar5为芳香或杂环芳香结构单元,X、Y和Z为连接两个或三个芳香环的桥接基团,n为1到4之间的整数。该有机化合物具有增强的共振因子和减小的Δ(S1−T1),从而有助于获得具有增加的光发射效率的热激发延迟荧光特性,并实现OLED元件的高效率和延长使用寿命。此外,该有机化合物的合成工艺简单且廉价。还提供了包含该有机化合物的混合物配方和有机电子器件。
