The synthesis of, two new poly(thienylene vinylene) derivatives is described, i.e. poly(3-octyl-2,5-thienylene vinylene) (O-PTV) and poly(bis[octylphenyl-2,5-thienylene vinylene]) (BOP-PTV). Both polymers have been prepared via the dithiocarbamate (DTC) precursor route. The polymerization protocol of the monomer toward the precursor polymer has been optimized by the use of different bases, leading
描述了两种新的聚亚噻吩乙烯撑衍生物的合成,即聚(3-辛基-2,5-噻吩撑乙烯撑)(O-PTV)和聚(双[辛基苯基-2,5-噻吩撑乙烯撑])( BOP-PTV)。两种聚合物均通过二硫代氨基甲酸酯(DTC)前体路线制备。通过使用不同的碱已经优化了单体向前体聚合物的聚合方案,从而提高了聚合步骤的可重复性。通过引入烷基侧链保证了可加工性。最后,将前体聚合物转化为共轭聚合物,并通过UV / vis,IR,GPC和循环伏安法对其进行了全面表征。以PCBM为受体的块状异质结太阳能电池显示出有希望的功率转换效率,对于BOP-PTV为0.80%,对于O-PTV为0.92%。
