Surface-enhanced fluorescence and surface-enhanced Raman scattering of ultrathin layers of bichromophoric antenna systems adsorbed on silver nanoisland films

We investigated a novel bichromophoric antenna system, characterized by energy transfer between a naphthalene group acting as the donor and a benzofurazane group acting as the acceptor. We studied the spectroscopic properties (infrared, Raman, UV–vis and fluorescence) of self-assembled monolayers of this molecular antenna on Ag nanoisland films and the energy-transfer process upon irradiation at 300 nm.
