Investigations into the effects of linker length elongation on the behaviour of calcium-responsive MRI probes
(Royal Society of Chemistry, 2019-07-25)
[Abstract] Understanding the relationship between chemical structure and the effectiveness of bioresponsive magnetic resonance imaging (MRI) contrast agents can offer help to identify key components required for the future ...
In-depth study of a novel class of ditopic gadolinium(III)-based MRI probes sensitive to zwitterionic neurotransmitters
(Frontiers, 2019-07-24)
[Abstract] The efficacy of Gd-based low-molecular weight ditopic MRI probes on binding zwitterionic neurotransmitters (ZNTs) relies on their structural compatibility. ZNTs are challenging biomarkers for monitoring chemical ...
The chemical consequences of the gradual decrease of the ionic radius along the Ln-series
(Elsevier, 2019-12-23)
[Abstract] In the periodical system, the lanthanides (the 15 elements in the periodic table between barium and hafnium) are unique in the sense that their trivalent cations have their valence electrons hidden behind the ...
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 ...
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 ...
endo- versus exo-Cyclic coordination in copper complexes with methylthiazolylcarboxylate tacn derivatives
(Royal Society of Chemistry, 2019-05-17)
[Abstract] Three tacn (1,4,7-triazacyclononane)-based ligands substituted by methylthiazolylcarboxylate (tha) and/or methylthiazolyl (th) arms have been examined for copper complexation with the aim to study the impact of ...
Reinforced Ni(ɪɪ)-Cyclam Derivatives as Dual ¹H/¹⁹F MRI Probes
(Royal Society of Chemistry, 2019-03-11)
[Abstract] Reinforced cross-bridged Ni²⁺-cyclam complexes were functionalised with pendant arms containing both amide protons and CF₃ groups that lead to a dual ¹H/¹⁹F response. The resulting complexes possess very high ...
Phosphate and polyphosphate anion recognition by a dinuclear copper(ii) complex of an unsymmetrical squaramide
(Royal Society of Chemistry, 2019-05-29)
[Abstract] In the search for receptors suitable for the recognition of phosphate or polyphosphate anions, a new unsymmetrical squaramide-based ligand bearing dipicolylamine (dpa) and ethylpiperazine units (L) was designed ...
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 ...
