Exceptionally inert lanthanide(III) PARACEST MRI contrast agents based on an 18-membered macrocyclic platform
(Wiley, 2015-12-14)
[Abstract] We report a macrocyclic ligand based on a 3,6,10,13-tetraaza-1,8(2,6)-dipyridinacyclotetradecaphane platform containing four hydroxyethyl pendant arms (L1) that forms extraordinary inert complexes with Ln3+ ions. ...
Magnetic anisotropies in rhombic lanthanide(III) complexes do not conform to Bleaney’s theory
(American Chemical Society, 2016-04-04)
[Abstract] We report a complete set of magnetic susceptibilities of lanthanide complexes with a macrocyclic ligand based on a 3,6,10,13-tetraaza-1,8(2,6)-dipyridinacyclotetradecaphane platform containing four hydroxyethyl ...
Developing the family of picolinate ligands for Mn2+ complexation
(Royal Society of Chemistry, 2016-12-22)
[Abstract] We have reported here a series of ligands containing pentadentate 6,6′-(azanediylbis(methylene))dipicolinic acid units that differ in the substituent present at the amine nitrogen atom (acetate: H3DPAAA; phenyl: ...
Synthesis and Structural Analysis of Push-Pull Imidazole-Triazole Based Fluorescent Bifunctional Chemosensor for CU2+ and FE2+ Detection
(Elsevier, 2022-07)
[Abstract] Fluorescent imidazole-triazole based ligands L1 and L2 have been designed as chemical push-pull chemosensors for divalent metal ions and synthesized through palladium-catalyzed cross-coupling reactions using ...
The relationship between NMR chemical shifts of thermally polarized and hyperpolarized 89Y complexes and their solution structures
(Wiley, 2016-11-07)
[Abstract] Recently developed dynamic nuclear polarization (DNP) technology offers the potential of increasing the NMR sensitivity of even rare nuclei for biological imaging applications. Hyperpolarized 89Y is an ideal ...
Thermodynamic Stability of Mn(II) Complexes with Aminocarboxylate Ligands Analyzed Using Structural Descriptors
(ACS, 2022-08-22)
[Abstract] We present a quantitative analysis of the thermodynamic stabilities of Mn(II) complexes, defined by the equilibrium constants (log KMnL values) and the values of pMn obtained as −log[Mn]free for total metal and ...
The role of ligand to metal charge-transfer states on the luminescence of Europium complexes with 18-membered macrocyclic ligands
(Royal Society of Chemistry, 2019-02-27)
[Abstract] We report a detailed study of the photophysical properties of EuIII and TbIII complexes with two ligands based on a 3,6,10,13-tetraaza-1,8(2,6)-dipyridinacyclotetradecaphane platform containing either four ...
Understanding the Effect of the Electron Spin Relaxation on the Relaxivities of Mn(II) Complexes with Triazacyclononane Derivatives
(American Chemical Society, 2021-10-07)
[Abstract] Investigating the relaxation of water ¹H nuclei induced by paramagnetic Mn(II) complexes is important to understand the mechanisms that control the efficiency of contrast agents used in diagnostic magnetic ...
On the Dissociation Pathways of Copper Complexes Relevant as Pet Imaging Agents
(Elsevier, 2022)
[Abstract] Several bifunctional chelators have been synthesized in the last years for the development of new 64Cu-based PET agents for in vivo imaging. When designing a metal-based PET probe, it is important to achieve ...
Versatile Macrocyclic Platform for the Complexation of [ⁿᵃᵗY/⁹⁰Y]Yttrium and Lanthanide Ions
(American Chemical Society, 2022-04-14)
[Abstract] We report a macrocyclic ligand (H3L6) based on a 3,6,10,13-tetraaza-1,8(2,6)-dipyridinacyclotetradecaphane platform containing three acetate pendant arms and a benzyl group attached to the fourth nitrogen atom ...
