高效稳有机蓝色荧光材料可以应用于白色光源和全色显示器件。设计合成了具有深蓝色荧光的三聚体3,7-双(9,9-二己基芴基)-2,8-二环己甲氧基-S,S-二氧化二苯并噻吩(FSOCyF)。首先在S,S-二氧化二苯并噻吩(SO)的2,8-位引入官能团环己甲氧基,以增加二苯并氧化噻吩的溶解性,将可溶性的二苯并氧化噻吩溴化后,与9,9-二己基芴-2-硼酸在钯催化下进行Suzuki-coupling反应,合成了分子内电荷转移型三聚体FSOCyF,并运用核磁共振氢谱/碳谱、元素分析、基质辅助激光解吸电离飞行时间质谱,X射线衍射以及荧光光谱对其结构和发光性能进行表征。
Efficient and stable organic blue fluorescent materials can be applied to white light and full color display devices. The trimer 3,7-bis (9,9-dihexylfluorenyl) -2,8-dicyclohexylmethoxy-S, S-dibenzothiophenol with a dark blue fluorescence was designed and synthesized ). First, a functional group, cyclohexylmethoxy, is introduced at the 2,8-position of S, S-dibenzodithiophene (SO) to increase the solubility of dibenzothiophene, and brominated dibenzothiophene And then reacted with 9,9-dihexylfluorene-2-boronic acid under palladium-catalyzed Suzuki-coupling reaction to synthesize an intramolecular charge transfer trimer FSOCyF. The structure of the product was characterized by 1H-NMR, 13C NMR, elemental analysis, Assisted laser desorption ionization time of flight mass spectrometry, X-ray diffraction and fluorescence spectroscopy to characterize its structure and luminescent properties.
