Probing the relative stability of thiolate- and dithiolate-protected Au monolayer-protected clusters.

Abstract

Dithiolate ligands based on (+/-)-alpha-lipoic acid derivatives have been investigated as ligands for both Au monolayer-protected clusters (MPCs) and mixed alkanethiol/dithiolate Au MPCs. The oxidative and thermal stability of the MPCs were investigated by a combination of UV-vis spectroscopy, TEM, and (1)H NMR experiments. Results show that the dithiolate… (More)
