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]− ...
Enhanced Photocatalytic Degradation of the Imidazolinone Herbicide Imazapyr upon UV/Vis Irradiation in the Presence of CaᵪMnOᵧ-TiO₂ Hetero-Nanostructures: Degradation Pathways and Reaction Intermediates
(MDPI, 2020-05-08)
[Abstract] The determination of reaction pathways and identification of products of pollutants degradation is central to photocatalytic environmental remediation. This work focuses on the photocatalytic degradation of the ...
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 ...
Europium(III) Macrocyclic Chelates Appended with Tyrosine-based Chromophores and Di-(2-picolyl)amine-based Receptors: Turn-On Luminescent Chemosensors Selective to Zinc(II) Ions
(Wiley, 2020-01-22)
[Abstract] Zinc ions play an important role in many biological processes in the human body. To selectively detect Zn²⁺, two EuDO3A‐based complexes (DO3A=1,4,7,10‐tetraazacyclododecane‐1,4,7‐tricarboxylic acid) appended ...
Improved Photocatalyzed Degradation of Phenol, as a Model Pollutant, over Metal-Impregnated Nanosized TiO₂
(MDPI, 2020-05-22)
[Abstract] Photocatalyzed degradation of phenol in aqueous solution over surface impregnated TiO₂ (M = Cu, Cr, V) under UV-Vis (366 nm) and UV (254 nm) irradiation is described. Nanosized photocatalyts were prepared from ...
Gold Nanoparticles as Colorimetric Sensors for the Detection of DNA Bases and Related Compounds
(MDPI, 2020-06-23)
[Abstract] Results regarding interaction of colloidal gold solutions with nucleobases, including uracil (U), as well as its sulfur derivatives, 2-thiouracil (2TU) and 4-thiouracil (4TU), cytosine (C), adenine (A), and ...
Face-Fusion of Icosahedral Boron Hydride Increases Affinity to γ‐Cyclodextrin: closo,closo‐[B₂₁H₁₈]⁻ as an Anion with Very Low Free Energy of Dehydration
(Wiley, 2020-03-12)
[Abstract] The supramolecular recognition of closo,closo‐[B₂₁H₁₈]⁻ by cyclodextrins (CDs) has been studied in aqueous solution by isothermal titration calorimetry and nuclear magnetic resonance spectroscopy. These solution ...
Inert macrocyclic Eu3+ complex with affirmative paraCEST features
(Royal Society of Chemistry, 2020-06-21)
[Abstract]: We report on a macrocyclic platform based on an 18-membered macrocycle that forms kinetically highly
inert paramagnetic complexes and possesses an excellent outlook for the development of bioresponsive
paraCEST ...
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 ...
