Embodiment 1

[0095] In a vacuum of 1×10 -5 Pa is deposited on a glass substrate with an anode of indium tin oxide (ITO) (thickness 100nm) by vacuum evaporation.

[0096] A compound HAT-CN was vapor-deposited on this substrate to form a hole injection layer (HIL) with a film thickness of 60 nm.

[0097] On the hole injection layer (HIL), compound NPB was then vapor-deposited to form a hole transport layer (HTL) with a thickness of 20 nm.

[0098] Compound 1 and Compound 2 were co-evaporated on the hole transport layer (HTL) to form an emitting layer (EML) with a thickness of 35 nm. The concentration of Compound 2 in the light-emitting layer (EML) was 97%, and the concentration of Compound B was 3%.

[0099] Compound A-2 and LiQ were co-evaporated on the emitting layer (EML), and the two materials were vaporized at the same rate to form an electron transport layer (ETL) with a thickness of 35 nm.

[0100] LiF was vapor-deposited on the electron transport layer (ETL) to form an electron in...

Embodiment 2-3

[0105] Using the compounds in Table 1 instead of Compound A-2, the same method as in Example 1 was used to fabricate an organic light-emitting device.

Abstract

The invention provides an organic compound and an organic light-emitting device, and belongs to the technical field of organic materials. The structure of the organic compound is shown as a formula I,and the organic compound can improve the performance of the organic light-emitting device.

Description

technical field [0001] The present disclosure relates to the technical field of organic materials, in particular to an organic compound and an organic electroluminescent device. Background technique [0002] An organic electroluminescent device generally includes an anode, a hole transport layer, an electroluminescent layer as an energy conversion layer, an electron transport layer and a cathode which are stacked in sequence. 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 move to the electroluminescent layer, and the holes on the anode side also move to the light-emitting layer, and the electrons and holes combine in the electroluminescent layer. Excitons are formed, and the excitons release energy outwards in an excited state, thereby making the electroluminescent layer emit light. . [0003] Traditional electron transport materials have low perfor...
