Surprising Complexity of the [Gd(AAZTA)(H2O)2]− Chelate Revealed by NMR in the Frequency and Time Domains
(American Chemical Society, 2021-12-10)
[Abstract] Typically, Ln(III) complexes are isostructural along the series, which enables studying one particular metal chelate to derive the structural features of the others. This is not the case for [Ln(AAZTA)(H2O)x]− ...
Expanding the Ligand Classes Used for Mn(II) Complexation: Oxa-aza Macrocycles Make the Difference
(MDPI, 2021-03-10)
[Abstract] We report two macrocyclic ligands based on a 1,7-diaza-12-crown-4 platform functionalized with acetate (𝑡O2DO2A²⁻) or piperidineacetamide (𝑡O2DO2AMᴾⁱᵖ) pendant arms and a detailed characterization of the ...
Thiosemicarbazone Modified Zeolitic Imidazolate Framework (TSC-ZIF) for Mercury(II) Removal From Water
(Royal Society of Chemistry, 2021-04-30)
[Abstract] Zeolitic imidazolate frameworks (ZIF-8), and their derivatives, have been drawing increasing attention due to their thermal and chemical stability. The remarkable stability of ZIF-8 in aqueous and high pH ...
Bifunctional Paramagnetic and Luminescent Clays Obtained by Incorporation of Gd³⁺ and Eu³⁺ Ions in the Saponite Framework
(American Chemical Society, 2021-07-08)
[Abstract] A novel bifunctional saponite clay incorporating gadolinium (Gd³⁺) and europium (Eu³⁺) in the inorganic framework was prepared by one-pot hydrothermal synthesis. The material exhibited interesting luminescent ...
Defining the Conditions for the Development of the Emerging Class of Feᴵᴵᴵ-Based MRI Contrast Agents
(Royal Society of Chemistry, 2021-07-26)
[Abstract] Fe(III) complexes are attracting growing interest in chemists developing diagnostic probes for Magnetic Resonance Imaging because they leverage on an endogenous metal and show superior stability. However, in ...
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 ...
Introducing Hyaluronic Acid into Supramolecular Polymers and Hydrogels
(American Chemical Society, 2021-10-18)
[Abstract] The use of supramolecular polymers to construct functional biomaterials is gaining more attention due to the tunable dynamic behavior and fibrous structures of supramolecular polymers, which resemble those found ...
Understanding the Effect of the Electron Spin Relaxation on the Relaxivities of Mn(II) Complexes with Triazacyclononane Derivatives
(American Chemical Society, 2021-10-07)
[Abstract] Investigating the relaxation of water ¹H nuclei induced by paramagnetic Mn(II) complexes is important to understand the mechanisms that control the efficiency of contrast agents used in diagnostic magnetic ...
Effect of Ionizing Radiation on Human Myeloperoxidase: Reaction With Hydrated Electrons
(Elsevier, 2021-11-27)
[Abstract] Myeloperoxidase (MPO) is a myeloid-lineage restricted enzyme largely expressed in the azurophilic granules of neutrophils. It catalyses the formation of reactive oxygen species, mainly hypochlorous acid, ...
Mechanical Stability Is Key for Large-Scale Implementation of Photocatalytic Surface-Attached Film Technologies in Water Treatment
(Frontiers, 2021-10-18)
[Abstract] Replacement of classical tertiary water treatment by chemical-free sunlight-driven photocatalytic units has been often proposed. Photocatalysts are required to be cost-effective, inert, chemically stable, reusable, ...
