Reaction Steps

As the first exemplary example for demonstrating the method of synthesizing monodisperse nanoparticles according to the present invention, 10.8 g of iron chloride [FeCl3.6H2O, 40 mmol] and 36.5 g of sodium oleate (120 mmol) were dissolved in a mixture of solvents containing 80 mL of ethanol, 60 mL of distilled water, and 140 mL of hexane, and thereafter the resulting mixture was heated to 70° C. and kept at the same temperature for 4 hours to obtain an iron-oleate complex. During this process, the initial scarlet color in aqueous phase became clear, and the initial transparent organic phase turned to scarlet, indicating that iron-oleate complex was successfully synthesized. When the reaction was completed, the upper organic layer containing the metal-oleate complex was separated and thereafter the hexane was evaporated off, resulting in a waxy solid form. In FIG. 1, the FT-IR spectrum of the resulting iron-oleate complex shows a C═O stretching peak at 1700 cm−1, which is a unique characteristics for a metal-oleate complex.
