Abstract
New polyether crown ligands containing four and five donor sites per molecule and with one or two of the ether linkages replaced by secondary or tertiary amino-groups have been synthesised. The synthesis did not work for potential crowns containing three donor atoms (nine-membered rings) but gave morpholines exclusively. Characterisation of the structures obtained by a variety of spectroscopic methods is discussed.Keywords
