title: The protective effect of the mesoporous host on the photo oxidation of fluorescent guests: a UV-Vis spectroscopy study.
abstract: The inclusion of fluorescent molecules within the pores of an inorganic host system is one of the most common ways used for the preparation of highly fluorescent nanosystems. The confinement of labile molecules usually leads to better performances mainly due to their protection against environmental parameters which can concur with the deactivation of the fluorescent ones. In this work the protective effect of the siliceous mesoporous host on photo oxidation of fluorescent guest molecules has been investigated under different experimental conditions, highlighting an outstanding photostability if compared to the performances exerted by the fluorescent dye in solution.
