Reactions of C=C Terminated Self-Assembled Monolayers in Gas-Phase Ozone
t 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 ... eased. This spectra obtained here suggests that the C=C-T SAM reacts with ozone to initially form a carboxylic acid intermediate that converts to a carboxylic anhydride group with more exposure.The RA ...
