routes toward the low band gap polymer poly(2,5-thienylene vinylene) (PTV) and derivatives have been studied. This study describes an extensive NMR characterization of 13C-labeled 3-octyl-PTV and its precursor polymer prepared via the dithiocarbamate route which is, since stable monomers are available, a promising route toward PTV derivatives. By introducing 13C-labeled vinylene carbons, we were able to
在过去的几十年中,已经研究了几种朝向低带隙聚合物聚(2,5-亚噻吩乙烯)(PTV)及其衍生物的合成途径。这项研究描述了通过二硫代氨基甲酸酯路线制备的13 C标记的3-辛基-PTV及其前体聚合物的广泛NMR表征,由于可获得稳定的单体,因此这是通往PTV衍生物的有希望的路线。通过介绍13C标记的亚乙烯基碳,我们能够定量地表征这些聚合物,同时考虑了会干扰共轭体系的端基和结构聚合缺陷。几种NMR技术和模型化合物的合成被用来完全指定质子和碳的化学位移。此外,将前体向共轭聚合物的经典使用热转化与更平滑,酸诱导的消除过程进行了比较。
