Abstract[English]
The present invention relates to the technical field of organic optoelectronic material preparation, and in particular to a hole transport material, an OLED containing the compound, and an organic light-emitting apparatus. The hole transport material uses triphenylamine as a core, with three side chains formed by an aromatic group, an alkyl-substituted fluorenyl group and heteroaryl group, and an ortho-substituted aryl group, enabling the compound to maintain high stability. In addition, when used to fabricate an organic EL element, the material effectively increases the luminous efficiency and operational lifetime of an organic light-emitting device, and has promising application prospects.[French]
La présente invention relève du domaine technique de la préparation de matériaux optoélectroniques organiques, et concerne en particulier un matériau de transport de trous, une DELO contenant le composé, et un appareil électroluminescent organique. Le matériau de transport de trous utilise de la triphénylamine en tant que noyau, avec trois chaînes latérales formées par un groupe aromatique, un groupe fluorényle à substitution alkyle et un groupe hétéroaryle, et un groupe aryle ortho-substitué, permettant au composé de maintenir une stabilité élevée. De plus, le matériau peut être utilisé pour fabriquer un élément électroluminescent organique, ce qui permet d'augmenter de manière efficace l'efficacité lumineuse et la durée de vie de fonctionnement d'un dispositif électroluminescent organique, et présente des perspectives d'application prometteuses.[Chinese]
涉及有机光电材料制备技术领域，尤其是一种空穴传输材料、具有该化合物的OLED和有机发光装置。空穴传输材料以三芳胺为母核，芳香基、烷基取代的芴基基团与杂芳基、邻位取代的芳基作为三个侧链结合，从而使化合物能保持较高的稳定性。同时，将其用来制作有机EL元件，有效提高有机发光器件的发光效率和工作寿命，具有很好的应用前景。
