• Self-Organizing Core−Shell Nanostructures:  Spontaneous Accumulation of Dye in the Core of Doped Silica Nanoparticles

  The process of formation of silica nanoparticles doped with a newly synthesized pyrene derivative has been investigated by means of fluorescence steady-state and time-resolved spectroscopy. The changes in the photophysical properties of the fluorophore were correlated to the increase of the nanoparticles hydrodynamic volume measured via dynamic light scattering (DLS) allowing us to determine the radial profile of the concentration of the dye. Experiments performed at a '' low '' degree of doping show that the fluorophore is almost completely included considerably before the end of the nanoparticles growth, allowing us to identify a self-organizing core-shell substructure. A strong enhancement of the fluorescence of the dye and a corresponding increase of its excited-state lifetime was observed upon its inclusion as a result of the shielding effect from molecular oxygen due to the silica matrix, a situation confirmed by the absence of the oxygen singlet emission in the near-infrared luminescence spectra. In the case of '' high '' loading, on the other hand, a heavily doped core showing an excimeric-like emission is first formed. Further growth leads to the formation of layers where the concentration of dye gradually decreases and the monomeric emission becomes relevant. The effect of the degree of doping on the kinetics of growth is also reported. At both concentration regimes, ultrafiltration experiments revealed the complete inclusion of the dye molecules. The average number of dye molecule per nanoparticles was also determined.

  Fluorescent organic-inorganic mesoporous hybrid materials have been prepared and characterised, and their behaviour against nitroaromatic explosives have been tested. MCM-41 silica was used as an inorganic scaffold and pyrene (P derivative containing trialkoxysilane moieties), dansyl and fluorescein (D and F derivatives also containing trialkoxysilane groups, respectively) fluorophores have been anchored
