  具有不断发展的能级和能隙的新型砜衍生化苯撑乙烯撑共轭共聚物的合成与表征

  摘要：

  合成并表征了一系列新的稳定，可加工和链端可官能化的砜衍生化的苯撑乙烯撑共轭聚合物（SFPV），它们包含不同的供体类型的共聚单体。聚合物主链由砜-亚苯基电子接受单元与供电子单元组成，供电子单元来自基于苯，噻吩和吡咯的二醛共聚单体之一（带有或不带有烷氧基侧链）。新聚合物（在溶剂中）的光能隙（E g）在1.9–2.3 eV的范围内，从含吡咯作为供体单元的聚合物获得的最低能隙。通过结合使用强供体单元（例如吡咯）和相对较弱但稳定的受体单元（砜取代的苯），可以将共轭聚合物的E g调整为低于2 eV，而与之前开发的基于S，S-二氧代噻吩基的PTV聚合物相比，聚合物主链上的亚乙烯基键在化学上仍能保持稳定的碱性条件。潜在的超分子嵌段共聚物体系。最低的能隙P（吡咯-SFPV）的光电功率转换效率是P（TV-SFPV）的10倍。©2011 Wiley Periodicals，Inc.
