The role of the capping bond effect on pyclen natY3+/90Y3+ chelates: full control of the regiospecific N-functionalization makes the difference
(Royal Society of Chemistry, 2017-09-07)
[Abstract] Thanks to a smart regiospecific N-functionalization, a pyclen based ligand bearing one picolinate and two acetate arms organized in a dissymmetric manner was synthesized for Y3+ complexation, and compared to its ...
Optimising the relaxivities of Mn2+ complexes by targeting human serum albumin (HSA)
(Royal Society of Chemistry, 2017-07-14)
[Abstract] We report two novel macrocyclic ligands based on the 1,4-DO2AM platform (1,4-DO2AM = 2,2′-(1,4,7,10-tetraazacyclododecane-1,4-diyl)diacetamide) and containing two benzyl groups attached either to the nitrogen ...
Tuning the copper(II) coordination properties of cyclam by subtle chemical modifications
(Royal Society of Chemistry, 2017-09-14)
[Abstract] The acid–base and copper(II) coordination properties of three previously described cyclam derivatives are reported. Potentiometry, mass spectrometry, UV-vis absorption spectroscopy, electrochemistry and theoretical ...
Spectrally undiscerned isomers might lead to erroneous determination of water exchange rates of paraCEST Eu(III) agents
(American Chemical Society, 2017-07-17)
[Abstract] We report a detailed study of the solution structure and water exchange rate of a Eu(III) complex with the cyclen-based ligand L1, containing (S)-2-(2-acetamido)-3-(4 (trifluoromethyl)phenyl)propanoate pendant ...
Effects of the substituents of pyrazole/thiazine ligands on the magnetic properties of chloro-bridged Cu(II) complexes
(Royal Society of Chemistry, 2017-09-07)
[Abstract] We have synthesised and characterised the dimeric copper(II) complexes [{CuCl(PzTz)}2(μ-Cl)2], [{CuCl(DMPzTz)}2(μ-Cl)2] and [{CuCl(DPhPzTz)}2(μ-Cl)2] and the monomeric complex [CuCl2(DMPzTz)] (PzTz = ...
