Description
Technical Field
The present disclosure relates to the field of organic materials, and more particularly, to a nitrogen-containing compound, an electronic component, and an electronic device.
Background
With the development of electronic technology and the advancement of material science, the application range of electronic elements for realizing electroluminescence or photoelectric conversion is becoming wider and wider. Such electronic components, such as organic electroluminescent devices or photoelectric conversion devices, generally include a cathode and an anode that are oppositely disposed, and a functional layer disposed between the cathode and the anode. The functional layer is composed of multiple organic or inorganic film layers and generally includes an energy conversion layer, a hole transport layer between the energy conversion layer and the anode, and an electron transport layer between the energy conversion layer and the cathode.
For example, when the electronic element is an organic electroluminescent device, it generally includes an anode, a hole transport layer, an organic light emitting layer as an energy conversion layer, an electron transport layer, and a cathode, which are sequentially stacked. When voltage is applied to the anode and the cathode, the two electrodes generate an electric field, electrons on the cathode side move to the organic light emitting layer under the action of the electric field, holes on the anode side also move to the organic light emitting layer, the electrons and the holes are combined in the organic light emitting layer to form excitons, and the excitons are in an excited state and release energy outwards, so that the organic light emitting layer emits light outwards.
