摘要

Work in this lab has recently focused on developing a method by which mixed self-assembled monolayers (SAMs) of alkanethiols on gold surfaces may be quantitatively analyzed by electrospray ionization mass spectrometry (ESI-MS). The approach that is currently being developed involves the use of hydrogen peroxide to oxidatively remove these films for direct infusion into the electrospray source. The rationale for these investigations, as well as preliminary studies of the experimental conditions necessary to produce various alkanesulfonates from their alkanethiol precursors, has been detailed recently.[1] In short, the goal in the preliminary studies has been the development of an oxidation process that yields the same sulfur oxidation product for each structurally distinct alkanethiol present. Such an approach should facilitate the quantification of complex SAMs that consist of multiple components.
