本文合成了新型的含磷硼多面体低聚倍半硅氧烷（PB-POSS）。首先，将3-缩水甘油氧基丙基三甲氧基硅烷（KH 560）与9，10-二氢-9-氧杂-10-磷杂菲-10-氧化物（DOPO）反应以制备含DOPO的硅烷偶联剂（DOPO-KH 560）。并将其水解缩合合成了含磷笼型倍半硅氧烷（DOPO-POSS）。最后，通过DOPO-POSS与硼酸反应制备了PB-POSS。采用傅里叶变换红外光谱、核磁共振、热重分析和差示扫描量热仪对PB-POSS的化学结构和热性能进行了表征。实验结果表明，PB-POSS的合成是成功的，所得化合物具有较高的热稳定性。
ABSTRACT In this study, the authors synthesized novel polyhedral oligomeric silsesquioxanes containing phosphorus and boron (PB-POSS). First, the 3-glycidoxy-propyltrimethoxy silane (KH560) was reacted with 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) to prepare silane coupling agent containing DOPO (DOPO-KH560). Then this product was used to synthesize polyhedral oligomeric silsesquioxanes containing phosphorus (DOPO-POSS) by a hydrolytic condensation. Finally, the PB-POSS was prepared by the reaction between DOPO-POSS and boric acid. The chemical structure and thermal properties of PB-POSS were characterized by Fourier transform infrared, nuclear magnetic resonance, thermal gravimetric analysis, and differential scanning calorimeter. The experiment results indicate that the synthesis of PB-POSS is successful, and the resulted compound has high thermal stability.
