Abstract

Phasing out: Nanoparticles can be stabilized by an ionic liquid polymer (ILP) composed of imidazolium units incorporating a hydrophobic benzyl group. The resulting gold, platinum, and palladium nanoparticles can be efficiently transferred from water to ionic liquids by exchange of the chloride anion of the ILP with the anion of the ionic liquid (see picture).
