Abstract

original image

The condensation of eight molecules in one step provides 1, the smallest [2]catenane to date, in 20% yield. The cavity in one of the identical macrocycles of the catenane has dimensions of 4 × 6 Å. The structure of 1 is earmarked by a variety of hydrogen bonds and tessellating stacks of aromatic units.
