Embodiment 1

[0201] Anode 1 was prepared by the following process: the thickness of ITO was The ITO substrate (manufactured by Corning) was cut into a size of 40mm (length) × 40mm (width) × 0.7mm (thickness), and it was prepared into a pattern with a cathode 5 overlapping area, an anode 1 and an insulating layer by using a photolithography process. Top emission experimental substrate, using ultraviolet ozone and O 2 :N 2 Plasma was used for surface treatment to increase the work function of the anode 1 (experimental substrate) and to clean the experimental substrate.

[0202] Vacuum-deposit m-MTDATA (4,4',4"-tris(N-3-methylphenyl-N-phenylamino)triphenylamine) on the experimental substrate (anode 1) to form a thickness of The hole injection layer 2 (HIL), and on the hole injection layer 2 vacuum evaporated NPB (N,N'-diphenyl-N,N'-(1-naphthyl)-1,1'-bi benzene-4,4'-diamine) to form a thickness of The hole transport layer 31 (HTL).

[0203] Evaporate TCTA (4,4',4 "-tris(carbazol-9-yl) ...

Embodiment 2～17

[0208] An organic electroluminescent device was fabricated by the same method as in Example 1 except that the compounds shown in Table 1 were each used in forming the electron transport layer 35 (ETL).

Abstract

The disclosure provides a compound represented by formula I, a photoelectric conversion device and an electronic device, belonging to the technical field of organic materials. The compound can reduce the operating voltage of the photoelectric conversion device, improve the luminous efficiency of the photoelectric conversion device, and prolong the life of the device.

Description

technical field [0001] The present disclosure relates to the technical field of organic materials, in particular, to a compound, a photoelectric conversion device and an electronic device. Background technique [0002] In recent years, with the development of semiconductor technology, photoelectric conversion devices have been widely used. For example, organic electroluminescent devices (OLED, Organic electroluminescent device) have gradually entered people's field of vision as a new generation of display devices. 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 light-emitting layer at the same time, and they combine to form excitons in the light-emitting layer, and the...
