  Abstract  
  A simple and environmentally friendly chemical reduction method to make iron nanostructures under ambient conditions in aqueous phase was developed. The reduction of Iron(III)chloride hexahydrate with sodium borohydride as reducing agent was performed at argon atmosphere to yield nanoparticles and nanochains. The morphologies of these nanostructures were studied with respect to the reactants molar ratios and reaction time. With the optimized research conditions, an in-situ chemical reduction method was performed to make poly(3-hexylthiophene) grafted metal-organic hybrid nanochains. These nanostructures and nanocomposites were characterized by transmission electron microscopy, revealing the dimensionalities of nanostructures. The photophysical properties observed from UV-Visible and fluorescence spectroscopies evidenced the formation of size-controlled iron nanoparticles and nanochains. The powder X-ray diffraction (XRD) pattern with the presence of [110] and [211] planes reveals the preferential packing of body-centered cubic crystal packing for iron nanostructures.
