The synthesis of Octakis [3- (3-amino propyl triethoxysilane) propyl] octa-silsesquioxane (APTPOSS), a derivative of polyhedral oligomeric silsesquioxane, was utilized to produce an efficient nanocomposite. MNPs@Silica/APTPOSS was characterized through scanning electron microscopy, Fourier transform infrared spectroscopy, vibrating sample magnetometry, X-ray diffraction, and Thermogravimetric analysis. These magnetic nanoparticles, a combination of organic-inorganic hybrid polyhedral oligomeric silsesquioxane, were utilized as a proficient heterogeneous catalyst in the one-pot synthesis of spirooxindoles derivatives. Furthermore, they could be swiftly isolated and reused six times while maintaining their catalytic efficiency.
八聚[3-(3-氨基丙基三乙氧基硅烷)丙基]倍半硅氧烷(APTPOSS)是一种多面体低聚倍半硅氧烷衍生物，其合成用于制备一种高效纳米复合材料。通过扫描电子显微镜、傅里叶变换红外光谱、振动样品磁强计、X射线衍射和热重分析对MNPs@二氧化硅/APTPOSS进行了表征。这些磁性纳米粒子是有机-无机杂化多面体低聚倍半硅氧烷的组合，被用作一锅法合成螺吲哚衍生物的高效多相催化剂。此外，它们可以快速分离并重复使用六次，同时保持其催化效率。
