SELF ASSEMBLED DIPYRROMETHANE THIN FILMS: SERS CHARACTERIZATION AND APPLICATION IN METHANOL VAPOURS RECOGNITION THROUGH SPR TECHNIQUE

摘要

A self-assembled monolayer of meso-(4-methylmercapto)dipyrromethane stopped on the silver surface has been prepared, characterized by SERS spectroscopy and tested in recognition of methanol vapours by surface plasmon resonance technique.
