Abstract

A series of catenanes was synthesized via self-assembly of dibenzo-24-crown-8, ethylenediamine, and either three, four, or five cyclidene units coordinating nickel(II) or copper(II) ions. A number of molecular necklaces were successfully isolated and characterized. ESI mass spectrometry proved to be the most useful analytical tool to establish the exact composition of synthesized catenanes. Additionally, single crystal of a grand macrocycle composed of four tetraazamacrocyclic units complexing copper(II) ions was obtained and its X-ray structure has been successfully determined.
