Notes:
The addition of β-cyclodextrin to a solution containing β-benzyloxy-α-propionic-substituted DOTA- and DTPA-Gd(III) complexes leads to the formation of inclusion compounds whose equilibrium constants have been determined by NMR titrations. The main effect associated with the formation of this ‘host-uest’ interaction is a marked elongation of the molecular reorientational time, τr, which in turn results in increased solvent proton relaxation rates.
