摘要：

Coinage metal salts (e.g. Au-III, Ag-I and Cu-II salts) readily react with thiols to give the corresponding metal(I) thiolates. These thiolate species are known to either self-assemble into insoluble polymeric species or to form soluble oligomers, depending on the nature of the thiol ligand. Here we demonstrate that this self-assembling ability can be applied to create supramolecular hydrogels. Glutathione (GSH), a naturally occurring tripeptide, has been used in combination with Au-III, Ag-I, and Cu-II salts to obtain pH responsive hydrogels that are able to gelate loo times their weight in water.
