Problems solved by technology

[0004]In the prior art, organic light-emitting diodes have self-luminous properties, and the materials that dominate their light emission are mainly electroluminescent materials. However, the current electroluminescent materials emit light Low efficiency often leads to failure of organic light emitting diodes, therefore, it is necessary to provide an electroluminescent material and an electroluminescent device with high luminous efficiency

Embodiment 1

[0195] Embodiment 1: the making of blue organic electroluminescent device

[0196] The anode was prepared by the following process: the thickness was The ITO substrate (manufactured by Corning) was cut into a size of 40mm × 40mm × 0.7mm, and it was prepared into an experimental substrate with cathode, anode and insulating layer patterns by using a photolithography process, using ultraviolet ozone and O 2 :N 2 Plasma surface treatment to increase the work function of the anode (experimental substrate), followed by descum removal.

[0197] Vacuum-deposit m-MTDATA (4,4',4"-tris(N-3-methylphenyl-N-phenylamino)triphenylamine) on the experimental substrate (anode) to form a thickness of hole injection layer (HIL).

[0198] Vacuum evaporate NPD (CAS: 495416-60-9) on the hole injection layer (HIL) to form a thickness of The first hole transport layer (HTL-1).

[0199] Evaporate TCTA (4,4',4"-tris(carbazol-9-yl) triphenylamine) on the first hole transport layer to form a thickn...

Embodiment 2～24

[0209] The organic electroluminescent device was prepared by the same method as in Example 1, the only difference being that when preparing the organic light-emitting layer (EML), the compound 10 (Dopant, the dopant material for the light-emitting layer) was replaced with those shown in Table 6. of organic compounds.

Abstract

The invention relates to an organic compound, and an electronic element and an electronic device using the same. The present disclosure relates to an organic compound having a structure represented bythe following formula (I): wherein A1, A2, A3 and A4 are the same or different from each other and are each independently selected from a benzene ring, a fused aromatic ring having 10-30 ring-formingcarbon atoms, and a fused heteroaromatic ring having 10-30 ring-forming carbon atoms. When the organic compound is used as an organic light-emitting layer material of an organic light-emitting device, the light-emitting performance of the device can be improved, and the service life of the device can be prolonged.

Description

technical field [0001] The present application belongs to the technical field of organic materials, and specifically provides an organic compound, an electronic component and an electronic device using the same. Background technique [0002] With the development of electronic technology and the progress of material science, the application range of electronic components for realizing electroluminescence or photoelectric conversion is becoming wider and wider. Such electronic components generally include a cathode and an anode oppositely arranged, and a functional layer arranged 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 located between the energy conversion layer and the anode, and an electron transport layer located between the energy conversion layer and the cathode. [0003] Taking an organic electroluminescent device as an exam...
