X-ray photoemission spectroscopy of sulfur-gold bond formation in monomer and polymer derived self-assembled monolayers


EMSL Project ID
2276

Abstract

X-ray photoemission spectroscopy will be used to examine sulfur-gold bond formation in monomer and polymer derived self-assembled monolayers on Au coated silicon and mica substrates. We are investigating the formation of surface-attached loops from a variety of dithiol and disulfide precursors. We prepare both compounds from readily available starting materials to give the dithiol monomer (I) and the disulfide-containing polyamide (II). In principle, both compounds could lead to the same surface-attached species in which both sulfurs attach to gold to form a loop.
