目前，制造最先进的高性能光学器件需要高折射率聚合物 (HRIP)。然而，由于这两个参数之间的典型权衡，很少有同时显示超高折射率（超过 1.8）和高阿贝数（超过 20）的 HRIP 被报道。在此，我们发现聚（2-羟基-1,4-苯硫醚）表现出前所未有的超高折射率（n（D）= 1.80），具有无定形性质，高玻璃化转变温度，良好的透明度和高阿贝数（nu（D）= 20）。光谱分析和密度测量表明，本体状态的羟基取代聚苯硫醚的致密氢键（H-键）网络能够实现超高折射率，而不会降低透明度。
High-refractive-index polymers (HRIPs) are currently in demand for the fabrication of state-of-the-art optical devices with high performance. However, few HRIPs that display both ultrahigh refractive index (over 1.8) and high Abbe number (over 20) have been reported owing to the typical trade-off between these two parameters. Herein, we found that poly(2-hydroxy-1,4-phenylene sulfide) exhibited an unprecedented ultrahigh refractive index (n(D) = 1.80) with an amorphous nature, high glass-transition temperature, good transparency, and high Abbe number (nu(D) = 20). Spectroscopic analyses and density measurements revealed that the dense hydrogen-bond (H-bond) networks of the hydroxy-substituted poly(phenylene sulfide) in the bulk state enabled the realization of an ultrahigh refractive index without any decline in transparency.
