Abstract
Monodispersed magnetite (Fe3O4) nanoparticles were obtained via an innovative three step synthetic approach. First, the formation of iron enneacarbonyl, Fe2(CO)9, a stable, solid organometallic complex compound, took place in a hexane solution, by the decomposition reaction of the unstable, liquid iron pentacarbonyl, Fe (CO)5, in the presence of sunlight and mild heating. In a second step, the dry compound Fe2(CO)9 was complexed with β-Cyclodextrin (β-CD) molecules, according to a combination of two modified complexation procedures. Steric hindrance of the organometallic molecules was achieved, among the interstices of the formed CD molecular network, which poses a novel, very crucial size control factor and stabilizing agent for the synthesized nanoparticles.
