The synthesis of amphiphilic sexithiophene–poly(ethylene oxide) segmented copolymers†
Abstract
Sexithiophene–poly(ethylene oxide) segmented copolymers with ethylene oxide blocks with Mn = 1000 and Mn = 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.
