The cover picture shows a typical example of a fluorophore‐heterofullerene conjugate which represents a molecular energy transducer. The heterofullerene moiety is the C 59 N cluster and the fluorophore is, in this case, phenanthrene. In a similar way other fluorophores such as fluorene and pyrene units can be attached to the heterofullerenes. In such architectures, conformations that allow for effective π‐π‐stacking interactions can easily be adopted. This leads to favourable electronic communication between the two subsystems. It was found that a common deactivation process of the photoexcited fluorophores takes place, namely, a quantitative energy transduction to the heterofullerene unit. Details are discussed in the article by A. Hirsch, D. Guldi et al. on p. 1741 ff.
