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 ... -
Viologen–cucurbituril host/guest chemistry – redox control of dimerization versus inclusion
(Royal Society of Chemistry, 2021-09-02)[Abstract] Two calix[4]arene systems, C234+ and C244+ – where 2 corresponds to the number of viologen units and 3–4 corresponds to the number of carbon atoms connecting the viologen units to the macrocyclic core – have ... -
Water exchange in lanthanide complexes for MRI applications. Lessons learned over the last 25 years
(Royal Society of Chemistry, 2019-06-19)[Abstract] The water exchange rates of water molecules coordinated to the metal ion in lanthanide complexes have been profusely investigated during the last 25 years, especially in the case of Gd3+ and Eu3+ complexes. This ... -
Water exchange rates and mechanisms in tetrahedral [Be(H2O)4]2+ and [Li(H2O)4]+ complexes using DFT methods and cluster‐continuum models
(Wiley, 2016-10-05)[Abstract] The water exchange reactions in aquated Li+ and Be2+ ions were investigated with density functional theory calculations performed using the [Li(H2O)4]+·14H2O and [Be(H2O)4]2+·8H2O systems and a cluster‐continuum ... -
Zn(II), Cd(II) and Pb(II) complexation with pyridinecarboxylate containing ligands
(Royal Society of Chemistry, 2008-09-09)[Abstract] Herein, we report the coordination properties towards Zn(II), Cd(II) and Pb(II) of two hexadentate ligands containing pyridinecarboxylate groups with ethane-1,2-diamine (bcpe) or cyclohexane-1,2-diamine (bcpc) ...
