Abstract

4,5-Dialkylated o-phenylenediamine with oligo(ethylene glycol) units is developed as a stabilizer with reducing property. It reduces chloroauric acid in water, giving lipophilic gold nanosheets whose surface is passivated by the quinoid-form ligands generated in situ. These nanosheets show brilliant golden luster in the solid state, whereas they are reversibly dispersible in organic media.
