Organic-inorganic hybrid nanomaterials prepared from 4-formyl benzo-12-crown-4-ether and silica coated magnetite nanoparticles

Silica coated magnetite nanoparticles were covalent grafted with 3- aminopropyl trimethoxysilane to give APTSCMNPs. Reaction of the resulted nanomaterial with 4-formyl benzo-12-crown-4 ether afforded FB12C4/APTSMNPs nanocomposite material in which the crown ether moiety was attached through propyl chain spacer. Characterization of the prepared nanocomposite was performed with different physicochemical methods such as FT-IR spectroscopy, thermogravimetric analysis (TGA-DTA), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and vibrating sample magnetometry (VSM).
