Abstract
(EN)
Disclosed by the present invention is a boron-containing compound and an application thereof to an organic light-emitting device. The compound has a boron atom structure and a strong rigidity. The compound has the advantages that molecules are not easily crystallized or gathered, and the compound has a good film-forming property. The compound according to the present invention has the characteristics of TADF. Due to the different electron donating ability of groups, materials are different in HOMO energy level, and such compound may be used as a material for different functional layers. In addition, the compound according to the present invention has a high fluorescence quantum efficiency and may effectively produce radiative transitions. Therefore, after the compound according to the present invention is applied to an OLED device as an organic electroluminescent functional layer thereof, the current efficiency, the power efficiency and the external quantum efficiency of the device may be greatly improved, and the service life of the device is obviously prolonged.
