Abstract
Gold nanostructures—nanowires and nanosheets—are reported to have been prepared from the gold salt HAuCl4 in a solid bulk phase of a block copolymer. The Figure shows a SEM image of nanosheets formed by thermal reduction at 70 °C. If water is included in the initial mixture and the reduction occurs by UV irradiation, predominantly nanowires are produced. Reasons for this distinction are discussed.
