Abstract[English]
The present invention relates to the technical field of the preparation of organic photoelectric materials, and in particular relates to a boron-nitrogen compound containing a carbazole group, and an OLED and an organic light-emitting device comprising same. According to the boron-nitrogen compound containing a carbazole group, by defining a combination of an aromatic group and a carbazole structure with a mother nucleus, the compound has an excellent light-emitting efficiency and a better thermal stability. Moreover, using the boron-nitrogen compound containing a carbazole group as a light-emitting layer material in an apparatus can effectively enable the organic light-emitting apparatus to have a lower driving voltage and maintain voltage stability. In addition, the light-emitting efficiency is improved, and the operating life is significantly extended, and thus the compound has good application prospects.[French]
La présente invention relève du domaine technique de la préparation de matériaux photoélectriques organiques, et concerne en particulier un composé bore-azote contenant un groupe carbazole, une DELO et un dispositif électroluminescent organique la comprenant. Le composé bore-azote contenant un groupe carbazole présente une excellente efficacité d'émission de lumière et une meilleure stabilité thermique, grâce à une combinaison d’un groupe aromatique et d’une structure carbazole dans un noyau mère. De plus, l'utilisation du composé bore-azote contenant un groupe carbazole en tant que matériau de couche électroluminescente dans un appareil peut permettre efficacement à l'appareil électroluminescent organique d'avoir une tension de commande inférieure et de maintenir une stabilité de tension. De plus, l'efficacité d'émission de lumière est améliorée, et la durée de vie est significativement étendue, et ainsi le composé présente de bonnes perspectives d'application.[Chinese]
涉及有机光电材料制备技术领域，尤其是一种含有咔唑基团的硼氮化合物、具有该化合物的OLED和有机发光装置。所述含有咔唑基团的硼氮化合物，通过限定芳香基团、咔唑类结构与母核的结合，使化合物具有优异的发光效率以及较好的热稳定性；同时所述含有咔唑基团的硼氮化合物作为发光层材料用于器件，可以有效地使有机发光器件具有更低驱动电压且保持电压的稳定性，且发光效率提高，工作寿命得以明显延长，具有很好的应用前景。
