Abstract

The present invention relates to a kind of pyrene quinone organic compound represented by general formula (I) and application thereof. The pyrene quinone organic compound has excellent hole transport properties and stability, can be used as a hole injection layer material in an organic electroluminescent element, and can also be used as a dopant doped in a hole injection layer or a hole injection layer. In the transport layer, this can not only be driven by low voltage, but also improve the efficiency of electroluminescence and prolong the life of the device.
