Abstract

Difficulties previously encountered in the very useful “click” functionalization of gold nanoparticles (AuNPs) resulting in low yields are now overcome by using specific conditions: 1 : 1 water–THF medium, stoichiometric CuSO4 and sodium ascorbate, inert atmosphere at 20 °C that provide quantitative “click” reactions between azidoalkylthiolate-AuNPs with various hydrophilic (PEG-containing) and hydrophobic (organic and organometallic) alkynes.
