Definition of the labile capping bond effect in lanthanide complexes
(Wiley, 2017-01-23)
[Abstract] Two macrocyclic ligands containing a cyclen unit, a methyl group, a picolinate arm, and two acetate pendant arms attached to two nitrogen atoms of the macrocycle either in trans (1,7-H3Medo2 ampa = 2,2′-(7-((6 ...
A combined NMR and DFT study of conformational dynamics in lanthanide complexes of macrocyclic DOTA-like ligands
(Royal Society of Chemistry, 2017-09-06)
[Abstract] The solution dynamics of the Eu(III) complexes of H4dota (1,4,7,10-tetraazacyclododecane-1,4,7,10-tetracarboxylic acid) and H5do3ap (1,4,7,10-tetraazacyclododecane-4,7,10-tris(carboxymethyl)-1-methylphosphonic ...
Ditopic receptors containing urea groups for solvent extraction of Cu(II) salts
(Royal Society of Chemistry, 2017-02-15)
[Abstract] The ditopic receptor L3 [1-(2-((7-(4-(tert-butyl)benzyl)-1,4,7,10-tetraazacyclododecan-1-yl)methyl)phenyl)-3-(3-nitrophenyl)urea] containing a macrocyclic cyclen unit for Cu(II)-coordination and a urea moiety ...
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 = ...
1,4,7‐triazacyclononane‐based bifunctional picolinate ligands for efficient copper complexation
(Wiley, 2017-05-10)
[Abstract] Three 1,4,7‐triazacyclononane‐based (tacn‐based) ligands containing picolyl and picolinate pendant arms (no3py, no2pa1py, and no3pa) were synthesized, and their copper(II) complexation properties were studied ...
Spectroscopic properties of a family of mono‐ to trinuclear lanthanide complexes
(Wiley, 2017-04-10)
[Abstract] A series of mono‐, di‐, and trinuclear complexes of Eu and Tb was designed to study the influence of the number of Ln emitting centers on the luminescence properties of discrete polynuclear complexes. The complexes ...
