The synthesis of a series of phosphine-functionalisedmacrocycles, 1–6, is described. The combination of N-and O-sites with P- and S-sites provides ligands which may bind transition or non-transition metal ions; as a consequence, they give access to dinuclear complexes containing both a Lewis acid and a redox metallic site. Compounds 1,2 and 6 are heterodinucleating ligands capable of binding two dissimilar
Derivatives of diaza-18-crown-6 and diaza-15-crown-5 were synthesized and their complexation properties were examined by solvent extraction and liquid membrane transport of various cations. N,N′-Bis(aminoalkyl) derivatives were particular in exhibiting unusually high but non-selective ion-binding efficiency toward various cations.
