The invention discloses an organic compound based on azabenzene and benzoheterocycle, a preparation method and application thereof, and belongs to the technical field of semiconductors. The structure of the compound provided by the invention is shown in general formula (1): General formula (1). The invention also discloses the application of the above organic compound. The compound structure of the present invention contains aza-benzene structures, and has high glass transition temperature and molecular thermal stability; low absorption in the visible light field, high refractive index, and can effectively improve the OLED device after being applied to the CPL layer of the OLED device The compound of the present invention also has a deep HOMO energy level and high electron mobility, and can be used as a hole blocking/electron transport layer material for OLED devices, which can effectively block holes or transfer energy from the light-emitting layer to the electron layer. One side, thereby improving the recombination efficiency of holes and electrons in the light-emitting layer, thereby improving the light-emitting efficiency and service life of the OLED device. |
