General description

3-Octylthiophene is an alkyl thiophene derivative. It has been synthesized by the reaction of 3-bromothiophene with octylmagnesium bromide.

Application

3-Octylthiophene may be used as a starting material in the synthesis of the following:
  • 2,5-dibromo-3-octylthiophene
  • poly(3-butylthiophene)-b-poly(3-octylthiophene), a diblock copoly(3-alkylthiophene)
  • regioregular poly(3-octylthiophene) (POT)
