Reactions of C=C Terminated Self-Assembled Monolayers in Gas-Phase Ozone

An important role in atmospheric chemistry is that of the reactions of ozone with unsaturated organic surfaces. Potential reactions sites for the atmospheric pollutant ozone are man-made materials that contain C=C functional groups. Previous research has shown that carboxylic acid-containing products were formed when unsaturated organic monolayers on silicon react with ozone; a band at 1860cm-1 shows the formation of a strained carbonyl species; oxidation of Au - S bonds in saturated self-assembled monolayers of alkanethiols on Au. This article explores the reaction mechanisms of ozone wit…
