摘　　要：文章选用咔唑类衍生物3,6–二溴咔唑为底物,2–噻吩硼酸为取代物,用四(三苯基膦)钯为催化剂,在四氢呋喃和甲苯的混合溶液中,无水无氧反应48 h合成咔唑类有机光电材料3,6–二噻吩基–9H–咔唑(BTC)。反应的原料摩尔配比即3,6–二溴咔唑∶2-噻吩硼酸为3∶7,得到产物0.705 g,产率为71%。利用红外光谱、紫外光谱、核磁共振氢谱对产物进行了定性分析,利用循环伏安法测化合物在不同扫速下的峰位和峰电流的变化,探究化合物的氧化还原机理。In this paper,3,6-di(2-thienyl)-9H-carbazole,a carbazole organic optoelectronic material,was synthesized in the mixture solution of tetrahydrofuran and toluene under water-free and oxygen-free conditions after reacting for 48 hours.The substrate,substitute and catalyst were 3,6-dibromocarbazole,2-thiopheneboronic acid and tetrakis(triphenylphosphine)palladium,respectively.The molar ratio of 3,6-dibromocarbazole to 2-thiopheneboronic acid was 3∶7,and 0.705 g product was obtained with a yield of 71%.The product were qualitatively analyzed using IR,UV and 1H NMR.Also,the changes of peak position and peak current of compounds at different scanning speeds were measured using cyclic voltammetry to clarify the redox mechanism of the compounds.
