The synthesis of amphiphilic sexithiophene–poly(ethylene oxide) segmented copolymers

Abstract

Sexithiophene–poly(ethylene oxide) segmented copolymers with ethylene oxide blocks with M_n = 1000 and M_n = 600 and with alternating hydrophobic and hydrophilic blocks sandwiching the sexithiophene blocks have been synthesised via Stille and Suzuki cross coupling reactions. All polymers showed limited solubility; the soluble low molecular weight fractions have been characterised by a combination of ¹H NMR spectroscopy and GPC.
