The present invention relates to a benzonaphthyridine derivative, an organic electroluminescent material and an organic electroluminescent element. The structural formula of the benzonaphthyridine derivative is shown in formula (I). When the benzonaphthyridine derivatives of the present invention are used to prepare organic electroluminescent elements, they have excellent electron mobility, thermal stability and light-emitting properties, and can be applied to the organic layer of organic electroluminescent elements. The benzonaphthyridine derivatives have good film-forming properties, and when applied to the electron transport layer and the electron transport auxiliary layer, they can produce lower driving voltage, higher light extraction efficiency and Longer-life organic electroluminescent elements, which in turn enable the manufacture of full-color display panels with improved performance and life. |
