Hybrid Photonic Antennae Based on Mesoporous Silica Frameworks

By F. Cucinotta, F. Carniato and L. Marchese

Abstract

This contribution describes design, preparation and physico-chemical characterization of a new photo-stable hybrid antenna based on mesoporous SBA-15 silica. Concepts of host-guest chemistry are applied in such a way that one or more photoactive guest molecules are incorporated into the silica channels and on the outer surface, acting as energy harvesting and transferring units. The presented composite system be-haves as efficient Förster resonance energy transfer (FRET) pair and shows high photoluminescence and stability towards photodegradation, representing an important step forward in the search for new efficient materials with opto-electronic applications.
