Problems solved by technology

However, when the material is used in an organic electroluminescent device, the luminous efficiency of the device still needs to be further improved.
[0007] CN104178120A discloses a blue phosphorescent host material containing benzimidazole units and its preparation method and an organic electroluminescent device. The blue phosphorescent host material has a higher triplet state energy level, and can effectively prevent energy from being passed back during the luminescence process. The host material greatly improves the luminous efficiency, but its thermal stability still needs to be further improved. When used in devices, the driving voltage and service life of the devices still need to be further optimized

Description

technical field [0001] The invention relates to the technical field of organic electroluminescence, in particular to a compound, an organic photoelectric device and electronic equipment. Background technique [0002] As a new generation of display technology, organic electroluminescent materials (OLED) have the advantages of ultra-thin, self-luminous, wide viewing angle, fast response, high luminous efficiency, good temperature adaptability, simple production process, low driving voltage, and low energy consumption. It has been widely used in industries such as flat panel display, flexible display, solid state lighting and vehicle display. [0003] According to the luminescence mechanism, it can be divided into two types: electrofluorescence and electrophosphorescence. Fluorescence is the radiation decay transition of singlet excitons, and phosphorescence is the light emitted by triplet excitons decaying to the ground state. According to the spin quantum statistical theory,...
