A strong charge‐transfer interaction between [10]cycloparaphenylene (CPP) and Li + @C 60 in the first CPP‐based ionic donor–acceptor supramolecule Li + @C 60 ⊂[10]CPP⋅X − is confirmed by electrochemical measurement and spectroscopic analyses. K. Itami and co‐workers show in their Communication on page 3707 ff. that the cationic charge on the Li + ion is delocalized not only onto the fullerene cage, but also further onto the outer CPP ring. Thus the whole compound is a well‐structured, supramolecular cation.
