Abstract
(EN)
Provided are a blue TADF material and a preparation method therefor, and an electroluminescent device. An alkyl chain capable of enhancing solubility is linked to the periphery of the blue TADF material, and a tert-butyl carbazole unit having a high energy level is linked to the tail end of the alkyl chain, so that good solubility of the material can be implemented while high luminous efficiency and TADF efficiency are obtained, and thus the material can be processed by spin coating of a solution. In addition, the carbazole at the tail end can serve as a body, so that undoping of a luminescent layer can be implemented, and phase separation can also be effectively avoided.

La présente invention concerne un matériau TADF bleu et son procédé de préparation, et un dispositif électroluminescent. Une chaîne alkyle pouvant améliorer la solubilité est liée à la périphérie du matériau TADF bleu, et une unité de tert-butyle carbazole ayant un niveau d'énergie élevé est liée à l'extrémité arrière de la chaîne alkyle, de sorte qu'une bonne solubilité du matériau peut être atteinte tout en obtenant un haut rendement lumineux et une haute efficacité TADF, et par conséquent le matériau peut être traité par dépôt à la tournette d'une solution. De plus, le carbazole à l'extrémité arrière peut servir de corps, de sorte que le non-dopage d'une couche luminescente peut être réalisé, et la séparation de phase peut également être efficacement évitée.
