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.
