Nevertheless, much less work has been devoted to the role of CNs as electron donors by formation of hybrids with strong electron acceptors; in this way, along the last years we have prepared several covalent or supramolecular hybrids between single wall carbon nanotubes, carbon nanohorns or graphene with fullerene derivatives. In this talk, I´ll present our last findings in the synthesis and properties of CN-electron acceptor hybrids.
