C-60 DERIVATIVES EMBEDDED IN SOL-GEL SILICA FILMS

Trasparent sol‐gel thin films and monoliths containing fullerene derivatives (e.g. see Figure) are reported. The sol‐gel technique provides a low‐temperature method to poduce homogeneous thin films and preliminary measurements reveal that these new commposite materials, the first sol‐gel materials to contain C60 or its derivatives, exhibit interesting optical limiting properties.
