高折射率噻蒽基聚苯硫醚（TPPSs）已被开发。以2，7-二氟噻蒽和二硫醇（包括4，4 ′-硫代二苯乙炔（TBBT）、间苯二硫醇（mBDT）或九水硫化钠）为原料，通过芳香亲核取代反应制备了TPPSs，并显示出优异的热稳定性，如在143-147 °C范围内的相对高的玻璃化转变温度和超过430 °C的5%失重温度。所有的TPPSs都表现出非常高的折射率，沿着达到1.8020，在可见光区具有高透明度，并且在0.0037-0.0039的范围内具有低双折射。
Highly refractive thianthrene-based poly(phenylene sulfide)s (TPPSs) have been developed. The TPPSs were prepared from 2,7-difluorothianthrene and dithiols, including 4,4′-thiobisbenzenethiol (TBBT), m-benzenedithiol (mBDT), or sodium sulfide nonahydrate based on aromatic nucleophilic substitution reactions, and showed excellent thermal stabilities such as relatively high glass transition temperatures in the range of 143–147 °C and 5% weight-loss temperatures over 430 °C. All of the TPPSs exhibited very high refractive indices reaching 1.8020 along with a high transparency in the visible region and low birefringence in the range of 0.0037–0.0039.
