ResumoThe binding properties, in aqueous solution, toward lithium ion of aza- and azaoxo- macrocycles with cage and cylindrical molecular topology are reviewed. The synthetic procedures and the acid–basic behavior are reported. Most of these compounds are able to selectively encapsulate the small lithium ion in aqueous solution. NMR spectroscopy, mainly 13C and 7Li, has been used to study the encapsulation equilibria. Few crystal structures of lithium complexes, indicating the lithium ion encapsulation have been reported.
