The Electrospray Mass Spectrometry (ES‐MS) of eight different supramolecular complexes shows that the molecular peaks of the desolvated multiply charged cations can be recorded more easily than by Fast‐Atom‐Bom‐bardment Mass Spectrometry (FAB‐MS) measurements of similar compound. The preliminary application of the ES‐MS technique to self‐assembled helical complexes obtained from ligands L 3 to L 8 with various metal ions (Cu, Co, Eu, Tb) indicates that ES mass spectra qualitatively reflect the species present MeCN solution.
