Abstract
An organic compound having the following structural formula is provided: wherein Arto Arare 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 eletronic device containing the organic compound are also provided.
