Noncovalent interactions between purified HiPCO single‐wall carbon nanotubes (SWNT) and a [60]fullerene–pyrene dyad, synthesized through a regioselective double‐cyclopropanation process, produce stable suspensions in which the tubes are very well dispersed, as evidenced by microscopy characterization. Cyclic voltammetry experiments and photophysical characterization of the suspensions in organic solvents are all indicative of sizeable interactions of the pyrene moiety with the SWNT and, therefore, of the prevalence in solution of [60]fullerene–pyrene⋅SWNT hybrids.
