摘要
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。
This work aimed at design and synthesis of a deep-blue fluorescent oligomer, i. e. , 3,7-Bis（9,9-dihexy- lfluorene-2-yl） 2,8 di（cyclohexylmethoxy） dibenzothiophene-S, S-dioxide （FSocy F）. Firstly, two cyclohexylmethoxy groups were introduced into the dibenzothiophene-S, S-dioxide （So） in order to modify its solubility. Then 3,7-dibromo-2,8-di（cy- clohexylmethoxy） dibenzothiophen^S, S-dioxide was obtained by bromization of the soluble Socy. Finally 3,7-dibromo-2,8- di（cyclohexylmethoxy）dibenzothiophene S, S-dioxide reacted with 9,9-dihexylfluorene-2-boronic acid in the presence of pal- ladium catalyst by Suzuki-coupling reaction,with formation of an intramolecular charge transfer oligomer, FSocy F. The re- sulting emissive oligomer was characterized by proton/carbon nuclear magnetic resonance spectroscopy （1 H/13C NMR）, el- emental analyses, MALDI-TOF mass spectrum,XRD and photoluminescence spectrum.
