图形摘要通过苯基硫代膦二氯化物与各种双酚的缩聚反应，合成了由聚硫代膦S组成的新型高折射率材料。这些聚合物具有优异的热稳定性(TD5和GT； 420 °C)、中到高玻璃化转变温度(117-204 °C)和可见光区域的高透明度。此外，由于其骨架中高极化的硫和磷原子以及相对较高的阿贝数(21.3%-27.5%)，它们获得了1.626-1.687的高折射率。
Graphical AbstractNovel high-refractive-index materials consisting of poly(thiophosphonate)s were developed by the polycondensation of phenylthiophosphonic dichloride with various bisphenols. These polymers exhibit excellent thermal stability (Td5> 420 °C), moderate to high glass transition temperatures (117–204 °C) and high transparency in the visible light region. Furthermore, they achieve high refractive indices of 1.626–1.687 owing to the highly polarizable sulfur and phosphorous atoms in their backbones and relatively high Abbe numbers of 21.3–27.5.
