Crowning glory: An unprecedented catenane that exhibits a donor–acceptor–donor–acceptor stacking motif was obtained through intramolecular Bingel reactions of fullerene monoadducts that bear a naphthalenetetracarboxylic diimide moiety, in the presence of 1,5-dinaphthocrown-10 ether at −78 °C (see scheme; DBU=1,8-diazabicyclo[5.4.0]undec-7-ene).
