Resumen:
Three fullerene derivatives have been employed with amphiphilic block copolymers both as structuredirecting
agents and doping molecules in one-pot synthesis of self-assembled 2D-hexagonal and cubic
porous silica mesostructures, in the form of bulk materials, thick cast films and thin films through an
evaporation-induced self-assembling procedure. Thermal calcination of the samples at 280 uC almost
completely removed the block copolymer from the silica matrix without substantial loss of the fullerene
additive, as demonstrated by FT-Raman spectra in which a clear signature of the fullerene Ag mode at
1467 cm21 was still clearly observed. Upon irradiation with laser light at 632.8 nm, the fullerene-doped
mesostructured materials exhibited photoluminescence at room temperature, which was not observed in
the silica matrix.uC almost
