1,10-Phenanthroline (phen) and 1,10-phenanthroline-terminated ruthenium(II) complex [Ru-Lphen]2+ have been used to stabilize and functionalize gold nanoparticles (Au-NPs). The strong interaction between the nitrogen atoms of phen and the surface of Au-NPs allowed for the phase transfer of Au-NPs from toluene to aqueous phase containing [Ru-Lphen]2+. Reverse phase transfer of these Au-NPs from water to acetonitrile by substituting the Cl− counter anion by PF−6 has also been demonstrated. Such facile post-functionalization, phase transfer and solvent transfer processes using metallic complexes bearing a terminal phenanthroline pendant group constitute a prerequisite for further studies of the electronic and optical properties of these NCs in various media.
1,10-Phenanthroline and ending ruthenium(II) complex [Ru-Lphen]2+ are used to stabilize Au-NPs. [Ru-Lphen]2+ is used as efficient transfer agent for the transfer of Au-NPs from toluene to water and to acetonitrile.Figure optionsDownload as PowerPoint slide
