Abstract :
Surface Enhanced Raman Scattering (SERS) experiments were performed on different interfaces consisting of nanostructured metals and ultra-thin layers of conjugated polymers. The Raman electromagnetic enhancement ensured by the surface roughness of different metals (Au, Ag or Al) permitted the monitoring of the optical and spectroscopic properties of ultra-thin polymer layers. In particular, in the case of a novel carbazolyldiacetylene deposited by self assembling on rough silver films or used as a capping agent for gold nanoparticles and subsequently polymerized by UV radiation, SERS experiments permitted detection of two polymer phases, characterized by a different degree of order in the polymer backbone: the highly conjugated blue phase and the less-extended red conformation.
