| Abstract: | New crownophane family was synthesized containing fragments of 2,7-dioxyfluorenone and hydroquinone connected with residues of tri- and tetraethylene glycols. The formation of inclusion complexes of these ligands with paraquat was established by means of mass spectrometry (fast-atom bombardment), 1H NMR and electronic spectroscopy. The crownophane with a larger ring formed the more stable complex. |
