Fibrous organosilicas functionalized with mercaptopropyl moieties (20 and 40 Mol‐% of –C 3 H 6 SH per Si) have been prepared through a smart, “one‐pot” sol‐gel route employing a phenazinic organogelator (DUOP) as a templating agent. The fibrous mercaptosilicas have been characterized morphologically (SEM observations) and chemically (Raman, 29 Si solid‐state NMR and chemical analysis), and the functionality of the final materials have been also confirmed by the efficient post‐grafting of Au nanoparticles. These fibrous gold‐mercaptosilica nanocomposite materials could be very useful for nanoelectronic or optoelectronic applications.
