Abstract

The present disclosure provides a nitrogen-containing compound, an electronic element, and an electronic device, and belongs to the technical field of organic materials. In the nitrogen-containing compound, 1-adamantyl and a cyano group are connected on a nitrogen-containing heteroaryl core structure by a linking group, so that the molecule has a high dipole moment as a whole, organic materials with a high electron mobility can be obtained, and the electron transport properties of the electronic element can be improved, and when the nitrogen-containing compound is used as an electron transport layer of an organic electroluminescent device, the luminous efficiency and service life of the device can be improved, and the operating voltage can be reduced.
