Detection and quantification of submonolayer coverage surface species is not trivial. We have developed a novel method sensitive to surface-bound chemical functional groups as low as 10(11) molecules/cm(2) by specific covalent attachment of fluorescent chromophores. This enables the intermediates of the UV photochemistry of alkylsiloxane self-assembled monolayers to be identified.
