Playing the hand-stacking game: The reaction of catenane-containing struts with Cu(NO3)2 produces extended frameworks, from whence both co-conformational selection and diastereoselection are observed following crystallization. Solid-state structures reveal the selective formation of stereoregular π–π stacks of enantiomeric pairs of donor–acceptor catenanes, despite the presence in solution of up to eight co-conformational and stereoisomers exhibiting planar chirality (see figure).
