以三氯丙基三甲氧基硅烷、苯基三甲氧基硅烷为原料,在一定条件下合成了笼形八聚(三氯丙基)倍半硅氧烷和双层倍半硅氧烷。进一步与叠氮钠、冠醚等通过取代反应、点击反应等方法来合成多种功能性的倍半硅氧烷,它们在复合材料等领域将有很好的应用前景。利用1-核磁共振光谱、13-核磁共振光谱、29-Si核磁共振光谱、基质辅助激光解吸电离飞行时间质谱等手段,对它们的结构分别进行了表征。
Using trichloropropyltrimethoxysilane and phenyltrimethoxysilane as raw materials, cage octa (trichloropropyl) silsesquioxane and bilayer silsesquioxane were synthesized under certain conditions. With sodium azide, crown ethers through the substitution reaction, click reaction and other methods to synthesize a variety of functional silsesquioxanes, they will have good application prospects in the field of composites and other fields. Their structures were characterized by 1-nuclear magnetic resonance spectroscopy, 13-nuclear magnetic resonance spectroscopy, 29-Si nuclear magnetic resonance spectroscopy, and matrix-assisted laser desorption / ionization time-of-flight mass spectrometry.
