Detection of aromatics in aqueous solution by surface-enhanced Raman scattering by substrates chemically modified with p-tert-butylcalix[4]arenetetrathiol

Chemical modification of rough silver surfaces by p-tert-butylcalix(4)arenetetrathiol (BCAT) has been shown to form substrates for surface-enhanced Raman scattering (SERS) that form reversibly complexes with aromatics from aqueous solution. Characteristic shifts of aromatics bands have permitted the...

Summary:Chemical modification of rough silver surfaces by p-tert-butylcalix(4)arenetetrathiol (BCAT) has been shown to form substrates for surface-enhanced Raman scattering (SERS) that form reversibly complexes with aromatics from aqueous solution. Characteristic shifts of aromatics bands have permitted the identification of benzene derivatives as well as mixture analyses.
