The present application provides a nitrogen-containing compound and electronic components and electronic devices thereof, belonging to the technical field of organic electroluminescence. The nitrogen-containing compounds in this application include three parts of nitrogen heterocyclic structure (pyridine, pyrimidine or triazine), fluorenyl structure and azaanthene and its derivatives. The nitrogen-containing compound of the present application constitutes a Donor-Acceptor (D-A, Donor-Acceptor) structure as a whole, and the overall structure has a relatively balanced charge transport capability, which enhances the electron conductivity of the electron transport material, thereby significantly improving the application of the nitrogen-containing compound. The luminous efficiency of electronic components of the compound, and the overall structure is not easy to crystallize and polymerize, and has good film-forming properties, so that the material has a longer life in electronic components. |
