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.

聚硫代膦酸酯的合成及高折射率特性

图形摘要通过苯基硫代膦酰二氯化物与各种双酚的缩聚，开发了由聚硫代膦酸酯组成的新型高折射率材料。这些聚合物表现出优异的热稳定性 (Td5 > 420 °C)、中到高的玻璃化转变温度 (117–204 °C) 以及在可见光区域的高透明度。此外，由于其骨架中的高度极化硫和磷原子以及 21.3-27.5 的相对较高的阿贝数，它们实现了 1.626-1.687 的高折射率。
