| Abstract: | A new pathway for the supramolecular synthesis of oligocatenanes is developed. It is based on a combination of most suitable macrocyclic structural units, obtained from tert‐butyl‐substituted isophthalic acid and terephthalic acid building blocks. These structural parts guarantee, on the one hand, the solubility of the catenanes and their intermediates, and, on the other hand, the preferred formation of larger ring sizes of the macrocycles to be intertwined. Acting as monotopic and ditopic concave templates, the tetra‐ and octalactam macrocycles were submitted to threading procedures to yield higher‐order catenanes of the amide type. By repetition of the threading steps, it was possible to isolate multiply mechanically connected n]catenanes up to n=4 composed of various macrocyclic units. |
