Surprising Complexity of the [Gd(AAZTA)(H2O)2]− Chelate Revealed by NMR in the Frequency and Time Domains
(American Chemical Society, 2021-12-10)[Abstract] Typically, Ln(III) complexes are isostructural along the series, which enables studying one particular metal chelate to derive the structural features of the others. This is not the case for [Ln(AAZTA)(H2O)x]− ... -
Dimer formation of GdDO3A-arylsulfonamide complexes causes loss of pH-dependency of relaxivity
(Royal Society of Chemistry, 2017-11-06)[Abstract] Gadolinium(III) complexes with pH-dependent relaxivities have been proposed as responsive magnetic resonance imaging (MRI) contrast agents (CA) for mapping of pH value in living subjects. The latter is clinically ... -
Accelerating water exchange in GdIII–DO3A-derivatives by favouring the dissociative mechanism through hydrogen bonding
(Royal Society of Chemistry, 2018-12-10)[Abstract] The GdIII-complexes of DO3A-acetophenone and ortho- or para- hydroxyacetophenone ligands have been investigated to assess the effect of the presence of a phenol group on the relaxivity and on the water exchange ... -
Controlling Water Exchange Rates in Potential Mn²⁺-Based MRI Agents Derived From NO2A²⁻
(Royal Society of Chemistry, 2019-02-22)[Abstract] We report a series of pentadentate ligands based on a 1,4,7-triazacyclononane-1,4-diacetic acid (H2NO2A) containing different substituents attached to the third nitrogen atom of the macrocyclic unit. Detailed ... -
Electronic versus steric control in palladium complexes of carboranyl phosphine-iminophosphorane ligands
(Royal Society of Chemistry, 2018-11-30)[Abstract] A new family of carboranyl phosphine-iminophosphorane ligands was prepared and characterized. The new ligands present a carboranyl group directly attached to the iminophosphorane nitrogen atom through a cage ...
