A molecular container for a single water molecule was obtained by chemical transformation of a [60]fullerene cage. A phosphate moiety acts as an effective “stopper” in the orifice (see picture).

A C60 fullereneopen-cage derivative with an 18-membered orifice reacts with electron-rich dienes on the rim of the orifice selectively. Both the mono and the bis adduct have been obtained in good yields by controlling the ratio of the reactants and the reaction time. Single-crystal structures show a head-to-tail and back-to-back dimer for the mono adduct of 1,4-diphenylbutadine and a head-to-tail
