Graphical Abstract

Trading places: Bifunctional thiol ligands were immobilized onto positively charged silica gel and onto Rink resin through electrostatic interactions. The image shows the place-exchange reaction between the alkanethiolate-protected gold nanoparticles and the polymer-bound bifunctional thiol ligands; monocarboxyl gold nanoparticles were obtained as the major product, cleaved off from the polymer support under mild conditions.
