Abstract: 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 (C) 2009 Elsevier B.V.
