A nanohybrid combining two allotropic forms of carbon, namely carbon nanohorns (CNH) and C 60 , has been obtained from a C 60 derivative bearing a benzocrown ether subunit (crown-C 60) and a CNH functionalized with NH 3 + groups (CNH-sp-NH 3 + F À) through ammonium-crown ether interactions. The resulting CNH-C 60 nanohybrid has been characterized by Raman and XPS spectroscopies, thermogravimetric analysis (TGA) and high-resolution transmission electron microscopy (HR-TEM). The photophysical properties of the CNH-C 60 conjugate have been investigated in benzonitrile. Femtosecond laser flash photolysis measurements revealed the occurrence of an efficient electron transfer from the singlet excited state of the C 60 moiety to the CNH with a rate constant of 6.5 Â 10 10 s À1 to produce a radical ion pair, which decayed by charge recombination with a lifetime of 1.0 ns to afford the triplet excited state of CNH-sp-NH 3 + F À and crown-C 60. The two carbon nanoforms play therefore complementary roles in the CNH-C 60 conjugate, the CNH acting as an electron donor and C 60 as an electron acceptor.

Three fulleropyrrolidine derivatives, characterized by the presence of positive charges, were introduced in the interlayer space of montmorillonite. The composites were characterized by powder X-ray diffraction and differential thermal and thermogravimetric (DTA-TGA) analysis, in conjunction with FTIR, UV-Vis, Raman, and (57)Fe-Mössbauer spectroscopies. Organophilic derivatives were intercalated into organically modified clays, while water-soluble fulleropyrrolidines were introduced into the clay galleries through ion exchange. The experiments, complemented by computer simulations, show that not all the clay-clay platelets are intercalated by the fullerene derivatives and that a sizable amount of charge transfer takes place between the host and the guests.
