Silver Nanoparticles Modified with Tetrathiafulvalene
2006
A new tetrathiafulvalene(TTF) modified silver colloid was prepared and characterized by means of TEM,IR,UVVis,Raman,and cyclic voltammogram.The surface of the silver nanoparticles was coordinated with 3,4-ethylenedisulfanyl-TTF thiolate.The TTF-modified Ag nanoparticles(about 70 nm) were monodispersed.Cyclic voltammogram of the TTF-Ag nanoparticles on a Pt electrode showed that it was a redox active nano-system.Two pairs of quasi-reversible redox waves appeared at E_(1/2)=+0.67 V and E_(1/2)=+0.86 V,corresponding to TTF/TTF~(·+) and TTF~(·+)/TTF~(2+),respectively.
