    • Molecular necklaces constitute a subset of catenanes. For a given number of rings, a molecular necklace is uniquely defined. A molecular necklace consisting of a total of n rings (n - 1 small rings threaded onto one larger ring) is denoted as [n]MN, which is a topological stereoisomer of [n]catenane. For example, the molecular necklace [5]MN described here and olympiadane synthesized by Stoddart and coworkers (D. B. Amabilino, P. R. Ashton, A. S. Reder, N. Spencer, J. F. Stoddart, Angew. Chem. 1994, 106, 450;
