Anthracene derivative containing multiple boron atoms and application thereof

The present invention relates to an anthracene derivative containing a plurality of boron atoms, an organic electroluminescent material, a light-emitting device and a consumer product, the anthracene derivative of the present invention is a novel organic electroluminescent compound having a macrocyclic planar structure formed by anthracene and a seven-membered ring, and the seven-membered ring anthracene derivative realizes HOMO and LUMO separation through a resonance effect between boron and nitrogen. Therefore, the TADF effect is realized, and the light-emitting wavelength is shorter than that of the existing compound; on the other hand, different substituent groups are introduced into a rigid framework, so that the delayed fluorescence lifetime and the half-peak width can be further adjusted. 本发明涉及一种含多个硼原子的蒽衍生物、有机电致发光材料、发光装置及消费型产品，本发明所述的蒽衍生物具备蒽与七元环形成大环平面结构的新型有机电致发光化合物，七元环蒽衍生物通过硼-氮之间的共振效应实现HOMO和LUMO分离，从而实现TADF效应，实现与现有化合物相比更短的发光波长；另一方面通过在刚性骨架上引入不同的取代基，能够实现对延迟荧光寿命和半峰宽的进一步调节。
