通过双(2,6-二甲氧基苯基)二硫醚的氧化聚合和随后的脱保护合成了二羟基取代的聚苯硫醚(DOHPPS)。多重氢键交联和噻吩主链的刚性的协同效应提供了致密但无定形的超分子网络，从而产生具有可见透明度和超高折射率（nD = 1.85）的聚合物。
Dihydroxy-substituted poly(phenylene sulfide) (DOHPPS) was synthesized via oxidative polymerization of bis(2,6-dimethoxyphenyl) disulfide and subsequent deprotection. The synergistic effect of multiple-hydrogen-bond cross-links and the rigidity of the thiophenylene backbone afforded dense yet amorphous supramolecular networks, resulting in a polymer with visible transparency and an ultrahigh refractive index (nD= 1.85).
