  Poly(3-hexylthiophene) (P3HT) was prepared by the oxidation coupling polymerization of 3-hexylthiophene (3HT) with molecular oxygen as an oxidant in the presence of vanadyl acetylacetonate (IV) (VO(acac)2) and ferric chloride (FeCl3). The polymerization at a molar ratio of VO(acac)2 / FeCl3 / 3HT = 1 / 2 / 5 in 1,2-dichloroethane at 0 °C for 164 h under oxygen gave P3HT in 61% yield. The resulting polymer gave a number average molecular weight (Mn) of 2.1 × 104 (Mw / Mn = 3.0; Mw: weight average molecular weight) and a head-to-tail content of 65%. The VO(acac)2-FeCl3 complex is supposed to work as a catalyst.
