Authors
abstract
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).

In this work, we report a new hybrid nanomaterial based on the immobilization of 4-formyl benzo-9-crown-3 ether (FB9C3) onto the mesopores of MCM-41. First, the mesoporous molecular sieve MCM-41 was covalently grafted with 3-aminopropyl triethoxysilane to give aminopropyl modified MCM-41 (AmpMCM-41). Reaction of this material with FB9C3 afforded the B9C3-AmpMCM-41 hybrid nanomaterial. The prepa...
