  Molecular self-assembled monolayers of ruthenium(II)-terpyridine dithiol complex on gold electrode and nanoparticles

  摘要：

  We describe the formation of stable dithiol-bifunctionalized Ru(II)-terpyridine monolayer onto gold electrode. The coverage-dependent behavior onto gold electrode has been studied by electrochemical technique. The stability, surface charge coverage, and electrontransfer kinetics were assessed by cyclic voltammetry. Functionalized monolayer-protected Au clusters (MPCs) were also prepared. The spectroscopic characterization data of MPCs using UV-Vis and TEM techniques are discussed. TEM images showed that functionalized spherical nanoclusters of 4.7 +/- 0.3 and 4.3 +/- 0.2 nm were produced. The particle sizes are uniform with a narrow size distribution. The morphology of Au(1 11) metal surface modified with MPCs was imaged using atomic force microscopy (AFM). The nanoparticle layer exhibits a distinct surface morphology, irregularly shaped domains with dimensions from 20 to 60 nm and root mean square heights of 2.401 nm. (c) 2007 Elsevier B.V.

  The reduction of tetrachloroaurate with sodium borohydride in the presence of 2,2′:6′,2″-terpyridyloctanethiol gave terpyridine-functionalized gold nanoparticles (Tpy–Au, core size 2.0 nm). Metal complexation of Tpy–Au with ruthenium-terpyridyl trichloride, Ru(tpy)Cl3, led to new gold nanoparticles bearing the ruthenium-terpyridine complex (Ru–Tpy–Au, core size 5.5 nm) which showed a characteristic MLCT (metal-to-ligand charge transfer) band in the visible region at 483 nm due to the terpyridine-ruthenium complex and a plasmon resonance at ∼510 nm in the UV-vis spectrum. The redox behavior of Ru–Tpy–Au was studied by cyclic voltammetry. Surface modification of metal electrodes was performed by the electropolymerization of pyrrole-functionalized Ru–Tpy–Au nanoparticles (Pyr–Ru–Tpy–Au) which were obtained from the ligand-exchange reaction of Ru–Tpy–Au with ω-(N-pyrrolyl)decanethiol.
