摘要：

Two new polymerisation routes to poly(4,4-dioctylcyclopentadithiophene-2,6-diyl) are reported. The polymer prepared by Kumada type cross-coupling showed significantly reduced molecular weight over that prepared by direct oxidative polymerisation using iron(III) chloride. The higher molecular weight polymer was shown to have extended conjugation by UV-visible spectroscopy.
