In this work, a new capping agent, cinnamic acid ( CA) was used to synthesize Au nanoparticles (NPs) under ambient conditions. The size of the NPs can be controlled by adjusting the concentration of reductant ( in our experiment sodium borohydride was used) or CA. The CA-stabilized Au NPs can self-assemble into 'nanowire-like' or 'pearl-necklace-like' nanostructures by adjusting the molar ratio of CA to HAuCl4 or by tuning the pH value of the Au colloidal solution. The process of Au NPs self-assembly was investigated by UV - vis spectroscopy and transmission electron microscopy. The results reveal that the induced dipole - dipole interaction is the driving force of Au NP linear assemblies.
