Title:
BORON-CONTAINING ORGANIC COMPOUND SERVING AS OLED DOPANT MATERIAL, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/063107
Kind Code:
A1
Abstract:
The present invention relates to the technical field of semiconductors. Provided are a boron-containing organic compound serving as an OLED dopant material, and an application thereof. The structure of the compound provided by the present invention is represented by the general formula (I). The compound of the present invention has a narrow full width at half maximum, a high fluorescence quantum yield, a high glass transition temperature, high molecular thermal stability, and suitable HOMO and LUMO energy levels. When the compound is used as a dopant material in the light-emitting layer material of an OLED light-emitting device, the current efficiency and external quantum efficiency of the device are significantly improved, and the purity of luminous color and the service life of the device are also greatly improved. The boron-containing organic compound of the present invention is used as the dopant material of a light-emitting layer, so that the device has good photoelectric properties.
