Problems solved by technology

The second is a phosphorescent material that can not only utilize 25% of the singlet S 1 excitons, and can also utilize 75% of the triplet T 1 Excitons, so the theoretical internal quantum efficiency can reach 100%, and the luminous effect on OLEDs is definitely better than that of fluorescent materials. However, since phosphorescent materials are mostly rare metal complexes, the material cost is relatively high, and blue phosphorescent materials have always existed. Applied to the problems of poor efficiency and lifespan in OLED
However, there are still not many such materials at present, and new high-performance TADF materials need to be developed urgently.

[0061] The starting material (1eq.) was reacted with imidazole (2.5eq.) in the presence of potassium carbonate (2eq.) and cuprous oxide (0.005eq.) to give intermediate a. Intermediate a is reduced by hydrogen to obtain intermediate b. Intermediate b (1eq.) brominated the amino group under the action of sodium nitrite (3neq.), hydrobromic acid (2.5neq.) and cuprous bromide (1.05neq.) to obtain intermediate c. Intermediate c (1eq.) was reacted with palladium acetate (0.05neq.), tri-tert-butylphosphine (0.075neq.) and cesium carbonate (1.5neq.) (1.1neq...

Abstract

An organic electroluminescenct compound, an application thereof in an organic photoelectric apparatus, and the organic photoelectric apparatus including the compound are provided.

Description

technical field [0001] The invention relates to the field of organic electroluminescent materials, in particular to organic electroluminescent materials and the application of the materials in organic photoelectric devices. Background technique [0002] In recent years, organic light-emitting diodes (OLEDs) have become extremely popular new-generation display products at home and abroad due to their advantages such as self-luminescence, high efficiency, wide color gamut, and wide viewing angle. At the same time, the organic materials used to make OLEDs play a crucial role. [0003] Among them, the material of the OLED light-emitting layer generates a singlet excited state (S 1 ) excitons and triplet excited states (T 1 ) excitons, according to spin statistics, the ratio of the two kinds of excitons is 1:3. According to different light-emitting mechanisms, the materials that can be used for the light-emitting layer of organic light-emitting diodes are generally as follows....
