Conformational and coordination equilibria on DOTA complexes of lanthanide metal ions in aqueous solution studied by {sup 1}H-NMR spectroscopy
- dell`Universita degli Studi di Torino (Italy); and others
The thermodynamic and chemical properties of Ln{sup III}(DOTA) complexes are the result of a very good match between sizes of Ln(III) ions and the preformed cavity of the DOTA ligand. These properties have been of primary importance in promoting the use of Gd(DOTA){sup {minus}} as a contrast agent for magnetic resonance imaging applications. 31 refs., 6 figs., 2 tabs.
