Disclosed in the present invention are an anthrone-containing and nitrogen-containing heterocyclic compound and applications thereof in OLEDs. The compound contains anthrone and has a nitrogen-containing heterocyclic structure, and the anthrone and the nitrogen-containing heterocyclic structure are both strong electron groups and have a very deep HOMO energy level and a high electron mobility; and the compound is suitable for being used as a hole blocking material or an electron transport material, and can also be used as a main material in an electron-type light-emitting layer. The electron groups of the compound in the present invention have high rigidity, and have the characteristics of being not easy to crystallize and gather among molecules, and having a good film-forming property. After the compound serving as an organic electroluminescent functional layer material is used in OLED devices, the current efficiency, the power efficiency and the external quantum efficiency of the devices are greatly improved, and the service life of the devices is remarkably improved. |
