Lead(II) complexes of lateral macrobicyclic receptors that incorporate a crown moiety and a pyridine head unit
(Wiley, 2010-11)
[Abstract] The coordinative properties towards lead(II) of two lateral macrobicyclic receptors that incorporate either a 1,10‐diaza‐[15]crown‐5 (L7) or a 4,13‐diaza‐[18]crown‐6 (L8) fragment are reported. Spectrophotometric ...
High relaxivity Mn2+-based MRI contrast agents
(Wiley, 2014-12-16)
[Abstract] Stable Mn2+ mono- and binuclear complexes containing pentadentate 6,6′-((methylazanediyl)bis(methylene)) dipicolinic acid coordinating units give remarkably high relaxivities due to the presence of two inner-sphere ...
Zn(II), Cd(II) and Pb(II) complexation with pyridinecarboxylate containing ligands
(Royal Society of Chemistry, 2008-09-09)
[Abstract] Herein, we report the coordination properties towards Zn(II), Cd(II) and Pb(II) of two hexadentate ligands containing pyridinecarboxylate groups with ethane-1,2-diamine (bcpe) or cyclohexane-1,2-diamine (bcpc) ...
Designing binuclear transition metal complexes: a new example of the versatility of N,N′-bis(2-aminobenzyl)-4,13-diaza-18-crown-6
(Royal Society of Chemistry, 2005-04-27)
[Abstract] N,N′-Bis(2-aminobenzyl)-4,13-diaza-18-crown-6 (L) is a versatile receptor able to adapt to the coordinative preferences of different metal cation guests. With first-row transition metal ions, L tends to form ...
The effect of ring size variation on the structure and stability of lanthanide(III) complexes with crown ethers containing picolinate pendants
(Royal Society of Chemistry, 2011-01-14)
[Abstract] The coordination properties of the macrocyclic receptor N,N′-bis[(6-carboxy-2-pyridyl)methylene]-1,10-diaza-15-crown-5 (H2bp15c5) towards the lanthanide ions are reported. Thermodynamic stability constants were ...
A merged experimental and theoretical conformational study on alkaline-earth complexes with lariat ethers derived from 4,13-diaza-18-crown-6
(Elsevier, 2011-02-05)
[Abstract] Herein, we report the synthesis and structural characterization of alkaline-earth complexes with the bibracchial lariat ethers N,N′-bis(2-aminobenzyl)-4,13-diaza-18-crown-6 (L2) and N,N′-bis(benzimidazol-2ylme ...
Applications of density functional theory (DFT) to investigate the structural, spectroscopic and magnetic properties of lanthanide(III) complexes
(Bentham Science, 2011)
[Abstract] Density functional theory (DFT) has become a general tool to investigate the structure and properties of complicated inorganic molecules, such as lanthanide(III) coordination compounds, due to the high accuracy ...
Ditopic receptors containing urea groups for solvent extraction of Cu(II) salts
(Royal Society of Chemistry, 2017-02-15)
[Abstract] The ditopic receptor L3 [1-(2-((7-(4-(tert-butyl)benzyl)-1,4,7,10-tetraazacyclododecan-1-yl)methyl)phenyl)-3-(3-nitrophenyl)urea] containing a macrocyclic cyclen unit for Cu(II)-coordination and a urea moiety ...
Self‐aggregated dinuclear lanthanide(III) complexes as potential bimodal probes for magnetic resonance and optical imaging
(Wiley, 2013-08-26)
[Abstract] Homodinuclear lanthanide complexes (Ln=La, Eu, Gd, Tb, Yb and Lu) derived from a bis‐macrocyclic ligand featuring two 2,2′,2′′‐(1,4,7,10‐tetraazacyclododecane‐1,4,7 triyl)triacetic acid chelating sites linked ...
Density functional dependence of molecular geometries in lanthanide(III) complexes relevant to bioanalytical and biomedical applications
(Elsevier, 2012-11-01)
[Abstract] A set of 15 lanthanide-containing model systems was used to evaluate the performance of 15 commonly available density functionals (SVWN, SPL, BLYP, G96LYP, mPWLYP, B3LYP, BH&HLYP, B3PW91, BB95, mPWB95, TPSS, ...
