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 ...
Stable Mn2+, Cu2+ and Ln3+ complexes with cyclen-based ligands functionalized with picolinate pendant arms
(Royal Society of Chemistry, 2015-01-20)
[Abstract] In this study we present the results of the equilibrium, dissociation kinetics, DFT and X - ray crystallographic studies performed on the complexes of metal ions of biomedical importance (Mn 2+ , Cu 2+ and ...
Modeling the OEC with two new biomimetic models: preparations, structural characterization, and water photolysis studies of a Ba–Mn box type complex and a Mn4N6 planar-diamond cluster
(MDPI, 2018-09-07)
[Abstract] The oxygen-evolving complex (OEC) is the native enzyme that catalyzes the oxidation of water in natural photosynthesis. Two new classes of manganese cluster complexes of formula Ba2Mn2L12(H3L1)2(CH3OH)4 1 and ...
Binuclear Co(II), Ni(II), Cu(II) and Zn(II) complexes with Schiff-bases derived from crown ether platforms: rare examples of ether oxygen atoms bridging metal centers
(Elsevier, 2010-05-26)
[Abstract] Bibracchial lariat ethers L3 and L4, derived from the condensation of N,N′-bis(2-aminobenzyl)-1,10-diaza-15-crown-5 or N,N′-bis(2-aminobenzyl)-4,13-diaza-18-crown-6 with salicylaldehyde, form binuclear complexes ...
Electronic versus steric control in palladium complexes of carboranyl phosphine-iminophosphorane ligands
(Royal Society of Chemistry, 2018-11-30)
[Abstract] A new family of carboranyl phosphine-iminophosphorane ligands was prepared and characterized. The new ligands present a carboranyl group directly attached to the iminophosphorane nitrogen atom through a cage ...
A Pentadentate Member of the Picolinate Family for Mn(ɪɪ) Complexation and an Amphiphilic Derivative
(Royal Society of Chemistry, 2018-12-04)
[Abstract] We report a pentadentate ligand containing a 2,2′-azanediyldiacetic acid moiety functionalized with a picolinate group at the nitrogen atom (H3paada), as well as a lipophylic derivative functionalized with a ...
Hyperfine coupling constants on inner‐sphere water molecules of GdIII‐based MRI contrast agents
(Wiley, 2012-11-02)
[Abstract] Herein we present a theoretical investigation of the hyperfine coupling constants (HFCCs) on the inner‐sphere water molecules of [Gd(H2O)8]3+ and different GdIII‐based magnetic resonance imaging contrast agents ...
Selective growth inhibition of cancer cells with doxorubicin-loaded CB[7]-modified iron-oxide nanoparticles
(Royal Society of Chemistry, 2017-05-03)
[Abstract] Cucurbit[7]uril-modified iron-oxide nanoparticles (CB[7]NPs) were loaded with doxorubicin hydrochloride (Dox) and tested as a drug delivery system. Dox was found to interact with the carbonyl-rich rims of the ...
Stimuli-responsive metal-directed self-assembly of a ring-in-ring complex
(Royal Society of Chemistry, 2016-06-06)
[Abstract] Concentration, temperature and/or solvent polarity control the speciation on the metal-directed self-assembly of a ditopic pyridyl ligand L with cis-protected Pd(II) metal centers. This results into a controllable ...
