Photoreductive synthesis of water-soluble fluorescent metal nanoclusters

Chem Commun (Camb). 2012 Jan 14;48(4):567-9. doi: 10.1039/c1cc16088e.

Abstract

Water-soluble fluorescent copper, silver and gold nanoclusters with quantum yields of 2.2, 6.8 and 5.3%, respectively, are prepared by a robust photoreduction of their inorganic precursors in the presence of poly (methacrylic acid) functionalized with pentaerythritol tetrakis 3-mercaptopropionate.
