Solid state and solution structures of alkaline-earth complexes with lariat ethers containing aniline and benzimidazole pendants
(Elsevier, 2012-01-04)
[Abstract] Herein we report the synthesis and structural characterization of Mg(II), Ca(II), Sr(II) and Ba(II) complexes with bibracchial lariat ethers derived from 1,7-diaza-15-crown-5 and 1,7-diaza-12-crown-4 containing ...
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 ...

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
