Paragraph 0058-0061; 0063, (2021/07/08)
The invention relates to a double-boron-containing organic electroluminescent material and application thereof, and belongs to the technical field of semiconductors, wherein the structure of the organic electroluminescent material is shown in a general formula (1). The invention also discloses application of the organic electroluminescent material. According to the invention, the compound provided by the invention has narrow half-peak width, high fluorescence quantum yield, high glass transition temperature and molecular thermal stability, and proper HOMO and LUMO energy levels; when the compound is used as a doping material in a luminescent layer material of an OLED luminescent device, the current efficiency and external quantum efficiency of the device are remarkably improved, the luminescent color purity is greatly improved, and the service life of the device is greatly prolonged; and the device has good photoelectric property when the double-boron-containing organic electroluminescent material is used as a luminescent layer doping material.
