Novel magnetic nanoparticles-supported inorganic-organic hybrids based on POSS as an efficient nanomagnetic catalyst for the synthesis of pyran derivatives

چکیده مقاله

A new family of polyhedral oligomeric silsesquioxanes with eight triethoxysilane arms (APTPOSS) has been successfully anchored on the surface of Fe3O4 nanomagnetics and characterized by infrared spectroscopy, X-ray diffraction spectroscopy, scanning electron microscope, Energy Dispersive Spectroscopy, thermogravimetric analysis, dynamic light scattering and vibrating sample magnetometer. Fe3O4@APTPOSS, as a magnetic nanocatalyst for high-yield synthesis of pyrans has been employed.
