咔唑衍生物已被广泛应用于有机电致发光材料,为提高咔唑的电子传输和空穴传输性能,本文以咔唑为起始原料,经N-烷基化、NBS亲电取代、甲酰化、丙二腈缩合反应,合成得到未见文献报道的双氰基功能性化合物6-溴-3-(2,2’-二氰基乙烯基)-N-正丁基咔唑,目标化合物经核磁(1 H-NMR)、质谱(MS)、元素分析、紫外可见分光光度计(UV-Vis)、荧光光谱和热重(TG)表征,结果表明该化合物有希望被用作蓝色有机电致发光材料。

Carbazole derivatives have been widely used as organic electroluminescence material. In order to improve the carbazole electronic and hole transport efficiency,carbazole was used as starting material,via N-alkylation,NBS electrophilic substitution, formylation,malononitrile condensation reaction, to prepare 6-bromo-3-（2,2＇-dinitrile vinyl）-N-buty!carbazo-le, an unreported dicyano functionalized compound. The structure and spectral properties of target compound were characterized by I H-NMR, MS, elemental analysis, UV-Vis, fluorescence spectrum and thermo-gravimetric analysis. The results show that the compound is a potential blue organic electroluminescent material.
