A series of aromatic polybenzoxazoles (PBOs) containing sulfur atoms in their main chains were developed. All of the PBOs were prepared from synthesized hydroxyl-diamine 4,4′-bis(4-amino-3-hydroxyphenylthio)diphenylsulfide (3SDA) and aromatic diacyl chlorides, such as 4,4′-((thiobis(4,1-phenylene))bis(sulfanediyl))dibenzoyl chloride (3SDBC), trans-1,4-cyclohexanedicarbonyl dichloride (trans-CHDC), isophthaloyl dichloride (IPC), and 4,4′-oxybis(benzoyl chloride) (OBC), via a conventional two-step procedure. The PBOs exhibited high thermal stability, thermal decomposition temperature (>430 °C), and glass-transition temperature (204–255 °C). The PBO derived from 3SDA and 3SDBC exhibited a very high refractive index, i.e., 1.7862 at 637 nm due to the high sulfur content (21.79%).

由含硫二苯甲酰氯衍生的高折射芳香族聚苯并恶唑

开发了一系列主链中含有硫原子的芳香族聚苯并恶唑（PBO）。所有 PBO 均由合成的羟基二胺 4,4'-双（4-氨基-3-羟基苯硫基）二苯硫醚（3SDA）和芳族二酰氯如 4,4'-（（硫代双（4,1-亚苯基))双（硫烷二基））二苯甲酰氯（3SDBC）、反式-1,4-环己烷二甲酰氯（反式-CHDC）、间苯二甲酰氯（IPC）和4,4'-氧双（苯甲酰氯）（OBC），通过传统的两步程序。PBO 表现出高热稳定性、热分解温度 (>430 °C) 和玻璃化转变温度 (204–255 °C)。由于硫含量高（21.79%），源自 3SDA 和 3SDBC 的 PBO 表现出非常高的折射率，即在 637 nm 处为 1.7862。
