| Abstract: | In a new two-phase system (tetrahydrofuran/saturated NaCl aqueous solution) monolayer protected clusters (MPCs) were prepared.The AuCl- 4 anion in saturated electrolyte aqueous solution was transferred into the organic phase of tetrahydrofuran by tetra-n-butylammonium bromide ((C 4H 9) 4NBr) and was reduced quickly by sodium borohydride in the presence of alkanethiol.The functionalized MPCs were characterized by solubility,transmission electron microscopy (TEM),Fourier transform infrared spectroscopy (FTIR),energy-dispersive X-ray (EDX) analysis and UV-vis spectroscopy.Electrochemical measurements of MPCs in CH 2Cl 2 exhibited 7 pairs of reversible voltammetric waves within the potential range of -1.0 to 1.0V (vs Ag/AgCl),which was ascribed to the quantized capacitance charging of nanoparticle double layers.All the results show that the new preparing method is feasible. |
