FeCl3 converts, in high yield, 3-butylsulfanyl-2,2â²-bithiophene into a tris(butylsulfanyl)sexithiophene, which shows interesting optical properties and forms a stable radical cation and dication.
β-Butylsulfanyl tetra-, sexa-, and octathiophenes were synthesized by oxidative coupling with iron(III) chloride from3-butylsulfanyl-2,2′-bithiophene. Tetrathiophene was also generated through coupling reac tions. The nmr characterization of oligomers is reported and discussed.
