Embodiment 1

[0102] Embodiment 1: the making of blue organic electroluminescent device

[0103] Anode 1 was prepared by the following process: the thickness of ITO was The ITO substrate was cut into a size of 40mm (length) × 40mm (width) × 0.7mm (thickness), and it was prepared into an experimental substrate with a cathode 5, an anode 1 and an insulating layer pattern by using a photolithography process, and the ultraviolet ray can be used to Ozone and O 2 :N 2 The surface is treated with plasma to increase the work function of the anode 1, and the surface of the ITO substrate can be cleaned with an organic solvent to remove impurities and oil stains on the surface of the ITO substrate. It should be noted that the ITO substrate can also be cut into other sizes according to actual needs, and the size of the ITO substrate in the present disclosure is not specifically limited here.

[0104] On the experimental substrate (anode 1), m-MTDATA (4,4',4"-tris(N-3-methylphenyl-N-phenylamino)trip...

The nitrogen-containing compound and the photoelectric conversion device of the present disclosure can improve the photoelectric conversion efficiency of the device and prolong the service life of the device.

Description

technical field [0001] The present disclosure relates to the field of optoelectronic technology, in particular, to a nitrogen-containing compound, a photoelectric conversion device and an electronic device. Background technique [0002] In recent years, an organic electroluminescent device (OLED, Organic electroluminescent device), as a new generation display technology, has gradually entered people's field of vision. A common organic electroluminescent device is composed of an anode, a cathode and an organic layer arranged between the cathode and the anode. When a voltage is applied to the cathode and anode, the two electrodes generate an electric field. Under the action of the electric field, the electrons on the cathode side and the holes on the anode side move to the functional layer at the same time, and they combine to form excitons in the functional layer, and the excitons are in the excited state. The state releases energy outward, and the process of changing from t...
