  • Abstract  Complex nano-architectures of different materials have very interesting geometry. Combining different metallic nanoparticles should allow the manufacture of novel nanocomposite materials with a plethora of exploitable electronic, optical, and magnetic properties.
     Thiolate-capped Au nanoparticles prepared by Brust-Schiffrin two phase method and carboxylate-capped Ag nanoparticles prepared by our one-step synthetic method are reported.
     We also developed and prepared Ag colloidal solution which can be used to form a high valuable conductive thin film by spin coating on Si wafer. Specific resistivity of 6.097 μΩ•cm for the silver metallic film (0.7 μm) on the Si wafer can be simply produced by thermal annealing of Ag MPCs film under an atmosphere of 10 % H2-90 % N2 at 300 ℃ for 1 h. Furthermore, it can be applied to make a micro-circuit by ink-jet printing technique.
     The characterizations of TEM, PXRD, UV-Visible, NMR, FT-IR, ESCA, TGA, TA-MS, EI-MS and SEM of Au and Ag nanoparticles are described.
     We hope the thiolate-capped Au nanoparticles and carboxylate-capped Ag nanoparticles could spontaneously self-connect to form the nanoscale alloy superlattice structure by the molecular recognizable bifuctional linkage.
