    • The dynamic covalent approach employs reversible reactions as the final covalent bond-forming step in the synthesis of catenanes or rotaxanes. Nevertheless, the resulting interlocked architectures are usually stable in the absence of catalysts or other additives

    • Because DABCO is also a strong ligand, the de-catenation may also result from its competitive coordination to the zinc porphyrin units of 2. Nevertheless, the result from both routes supported the formation of the dynamic [2]catenane in the solution.
