For the formation of oligothiophenes or thiophene co-oligomers, a preconnected method using zirconacyclopentadienes was demonstrated. Oligoynes of 4,4-bis(butoxymethyl)-1,6-heptadiyne linked through bithiophene were prepared where all components and diyne moieties were connected in advance before converting to zirconacyclopentadiene-containing precursors. Treatment of the reactive zirconacyclopentadienes in the preconnected precursors with acid, dimethyl acetylenedicarboxylate or sulfur monochloride afforded different oligothiophenes or thiophene co-oligomer derivatives.
对于寡噻吩或噻吩共寡聚物的形成,已经展示了使用锆环戊二烯作为预连接方法的应用。通过双噻吩连接的4,4-双(丁氧甲基)-1,6-庚二炔的寡炔制备中,所有组成部分和二炔基团在转化为含锆环戊二烯的前体之前均预先连接。通过酸、二甲基乙炔二羧酸酯或一氯化硫处理这些预连接前体中的活性锆环戊二烯,可以获得不同的寡噻吩或噻吩共寡聚物衍生物。
