一种结构明确的新结构四联噻吩化合物:5,5’-二[2,5-二(三甲基硅)-3-噻吩]基-2,2’-联噻吩(1)被有效合成出来。以2,3’-联噻吩(4)为建筑模块,通过NBS选择性溴代高产率得到5-溴-2,3’-联噻吩(5),进而通过氯化铜氧化偶联有效的合成出1。本文还对目标产物的单晶结构和紫外吸收光谱进行了分析。 A Novel Tetra-thiophene Structure with New Structure: Synthesis of 5,5’-bis [2,5-bis (trimethylsilyl) -3-thienyl] -2,2’-bithiophene come out. With 2,3’-bithiophene (4) as the building block, 5-bromo-2,3’-bithiophene (5) was obtained by selective NBS selective bromination and then was efficiently synthesized by copper chloride oxidative coupling Out 1. The crystal structure and UV absorption spectrum of the target product were also analyzed.
