Sexithiopheneâpoly(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.
已经通过Stille和Suzuki交叉偶联反应合成了具有氢氧化物区块的性
硫烯-聚
乙烯氧化物分段共聚物,Mn = 1000和Mn = 600,并且具有交替的疏

硫烯区块之间。所有聚合物的溶解性有限;可溶性低分子量部分已通过1H NMR光谱和
GPC的组合进行表征。
