Abstract
The surface of magnetic nanoparticles (Fe3O4) has been modified chemically with iron phthalocyanine monolayer. The under-coordinated Fe sites on the surface of SCFD-derived Fe3O4 nanoparticles (NPs) and phthalic nitrile acted as template ions and components, respectively, for the formation of FePc. The presence of chemical linkages between in situ formed FePc monolayer and the surface of Fe3O4 NPs has been characterized by TEM, FTIR, UV-Vis, MS and TG-DSC etc. As compared to the neat Fe3O4 nanoparticles, the FePc monolayer-protected Fe3O4 nanoparticles (FePc@Fe3O4 NPs) that resulted could be dissolved in common organic solvents and showed much higher antioxidativity to oxygen.
