The chosen one : A molecular cage has been shown to form pseudorotaxane‐like complexes with threaded anthraquinone and squaraine units in the presence of templating Na + ions (see picture). The complexation and decomplexation of the pseudorotaxane complexes in solution occur with significant color changes which allows this ion‐specific templating effect to be easily monitored with the naked eye.
