Abstract
Provided are an organic compound, a P-type doped material and an application thereof. The organic compound has a structure represented by Formula I, and through a molecular structure design, the organic compound has a lowest unoccupied molecular orbital energy level which is close to an anode work function and a highest occupied molecular orbital energy level of a hole transport layer, effectively promoting the generation of holes. The organic compound has a suitable molecular weight, low volatility and high stability, sufficiently satisfying an evaporation preparation process of OLED devices; moreover, the synthesis method is simple and low cost, achieving large-scale application. As an organic electroluminescent material, the organic compound can be used as the P-type doped material, especially suitable for a charge injection layer of organic electroluminescent devices, which can adjust charge balance of devices, effectively improve efficiency and lifetime of devices and reduce drive voltage and energy consumption.
