Enhancing the electrocatalytic activity of Fe phthalocyanines for the oxygen reduction reaction by the presence of axial ligands: Pyridine-functionalized single-walled carbon nanotubes
(2021)
We have examined the electrocatalytic activity of iron phthalocyanine (FePc) and perchlorinated iron phthalocyanine 16(Cl)FePc for the oxygen reduction reaction (ORR) in alkaline medium with the two molecules either adsorbed ...
Pyridine as axial ligand on the [mo6cl8](4+) core switches off luminescence
(ELSEVIER SCIENCE BV, 2009)
Axial ligand influence on geometries, charge distributions and electronic structures of iron tetraazamacrocycle [Fe((II))TIM(X)(Y)](2+) complexes assessed by Density Functional Theory
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
We employed the Density Functional Theory along with small basis sets, B3LYP/LANL2DZ, for the study of FeTIM complexes with different pairs of axial ligands (CO, H(2)O, NH(3), imidazole and CH(3)CN). These calculations did ...
Liquid-crystalline coordination polymers based on tetra(alkoxybenzoato)dirhodium(II) complexes axially linked by tetrazine, phenazine and 4,4′-bipyridine
(Taylor & Francis Ltd, 2017-11)
The reaction of dirhodium tetrakis(3,4,5-trialkoxy)benzoates Rh2(B3OCn)4 (n = 10, 14, and 18) with three different dinitrogenated axial ligands (Lax), namely tetrazine (tz), phenazine (phz), and 4,4′-bipyridine (bpy), gave ...
Electron Spin Density on the Axial His Ligand of High-Spin and Low-Spin Nitrophorin 2 Probed by Heteronuclear NMR Spectroscopy
(American Chemical Society, 2013-01)
The electronic structure of heme proteins is exquisitely tuned by the interaction of the iron center with the axial ligands. NMR studies of paramagnetic heme systems have been focused on the heme signals, but signals from ...
Copper(II) complexes with new polypodal ligands presenting axial-equatorial phenoxo bridges {2-[(Bis(2-pyridylmethyl)amino)methyl]-4-methyl phenol, 2-[(Bis(2-pyr1dylmethyl)amino)methyl]-4-methyl-6-(methylthio)phenol}: Examples of ferromagnetically coupled
(2007)
Two new ligands, 2-[(bis(2-pyridylmethyl)amino)methyl]-4-methylphenol (HL) and 2-[(bis(2-pyridylmethyl)amino)methyl]-4-methyl-6-(methylthio)phenol (HSL), were synthesized and were used to prepare the trinuclear copper(II) ...
Coupling of tyrosine deprotonation and axial ligand exchange in nitrocytochrome c
(Royal Society of Chemistry, 2014-02)
Here we report a spectroscopic, electrochemical and computational study of cytochrome c showing that nitration of Tyr74 induces Tyr deprotonation, which is coupled to Met/Lys axial ligand exchange, and results in concomitant ...
Unexpected electron spin density on the axial methionine ligand in CuA suggests its involvement in electron pathways
(Royal Society of Chemistry, 2020-01)
The CuA center is a paradigm for the study of long-range biological electron transfer. This metal center is an essential cofactor for terminal oxidases like cytochrome c oxidase, the enzymatic complex responsible for ...
Building Pyridinium Molecular Wires as Axial Ligands for Tuning the Electrocatalytic Activity of Iron Phthalocyanines for the Oxygen Reduction Reaction
(AMER CHEMICAL SOC, 2018)
We have been able to"tune"the electrocatalytic activity of iron phthalocyanine (FePc) and iron hexadodeca-chlorophthalocyanine (16(Cl)FePc) for the oxygen reduction reaction (ORR) by manipulating the"pull effect"of pyridinium ...
