Stable monometal and bimetal monolayer protected clusters (MPCs) of noble metals have been studied where chromatographic separation was used to obtain monodisperse samples. Monometal MPCs were synthesized using a modified Brust synthesis. Both a modified Brust synthesis and the galvanic exchange reaction were used to synthesize bimetal MPCs. These synthetic procedures yield different core compositions resulting in different properties. A wide variety of techniques were used to study these MPCs including reverse phase ion-pair high performance liquid chromatography (HPLC), luminescence spectroscopy, UV-vis spectroscopy, electrochemistry, transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS).
