Synthesis and characterisation of a Cd(II) complex with a chiral framework constructed from achiral 1,1′-[bis-3-(3-pyridyl)pyrazol-5-yl]ferrocene via spontaneous resolution

The chiral Cd(II) complex {[Cd(L)(CH3COO)2(H2O)]H2O}n {L = 1,1′-[bis-3-(3-pyridyl)pyrazol-5-yl]ferrocene} has been synthesised. The Cd(II) ion is coordinated by two pyridyl nitrogen atoms, two chelating acetate anions and one water molecule, showing a distorted pentagonal-bipyramidal coordination environment. Each ligand L serves as a bisconnector, bridging two Cd atoms through its two pyridyl moieties, to afford an infinite 1D left-handed helical chain along the a-axis with a short pitch of 5.8761 (9) A. Moreover, all of the left-handed helical chains are joined by hydrogen bonds to form a left-handed homochiral crystal.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, HPLC of Formula: C11H3FeO, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 1273-86-5, Name is Ferrocenemethanol, molecular formula is C11H3FeO

Scanning microelectrochemical characterization of the anti-corrosion performance of inhibitor films formed by 2-mercaptobenzimidazole on copper

The aim of this work is to explore the applicability of the scanning electrochemical microscope (SECM) to characterize the inhibiting effect of 2-mercaptobenzimidazole against the corrosion of copper. SECM was operated in the feedback mode by using ferrocene-methanol as redox mediator, and the sample was left unbiased at all times. The kinetic changes in the corrosion processes were monitored over time from the Z-approach curves. Furthermore, inhibitor-modified copper samples presenting various surface finishes were imaged by SECM and the scanning vibrating electrode technique (SVET), allowing changes both in the surface activity of metal-inhibitor films and in the extent of corrosion attack to be spatially resolved. Differences in the local electrochemical activity between inhibitor-free and inhibitor-covered areas of the sample were successfully monitored.

Responsive Gel-like Supramolecular Network Based on Pillar[6]arene-Ferrocenium Recognition Motifs in Polymeric Matrix

A dual-responsive supramolecular network based on pillar[6]arene-ferrocenium redox-controllable recognition motifs in polymeric backbones is constructed with a ferrocenium-functionalized copolymer and a pillar[6]arene copolymer, in which the first example of pillar[6]arene-functionalized copolymer was synthesized through the reversible addition/fragmentation chain-transfer copolymerization of an acrylate-functionalized pillar[6]arene and methyl acrylate. The resulting supramolecular network exhibits dramatically increased viscosity than the non-cross-linked mixtures and demonstrates a gel-like behavior on macroscale with a transient-network behavior revealed by rheology study. Furthermore, the viscoelastic properties of such supramolecular network can be easily controlled by different external stimuli including redox stimulus and competing host/guest reagents.

Structures and properties of ferrocene derivatives with different kinds of nitroxide radicals

Three ferrocene derivatives carrying different kinds of nitroxide radicals (1-3) were prepared as dual redox compounds. All of them have distorted molecular conformations between a Cp unit of a ferrocene group and a nitroxide group and the largest dihedral angle between the units is observed in the PO derivative 3. A unique magnetic behavior with a spin gap is disclosed in the derivative 3, reflecting two-dimensional interactions between the paired spins. Each derivative has two oxidation potentials based on both ferrocene and nitroxide groups and multi-step charge-discharge processes are found for all derivatives with the first discharge capacity over 200 A h kg-1.

Redox Activity of Vinylferrocene Copolymers by Electron Hopping Reaction in the Absence of Fluid Solvents

A series of novel copolymers consisting of a redox monomer, vinylferrocene, and an ion-conducting monomer, omega-methacryloyl-alpha-methoxy-oligo(ethylene oxide) (average molecular weight = 470), have been prepared by radical copolymerization and characterized.Ionic conductivity and redox activity of the copolymers, complexed with lithium perchlorate, have been explored by using complex impedance spectroscopy and solid state voltammetry with microelectrodes, respectively.The copolymer/salt complexes exhibit ionic conductivity of 1E-5 S cm-1 at room temperature and chemically reversible redox activity by themselves without any fluid solvents.The redox activity can be assigned to redox reactions of ferrocene sites in the bulk polymeric phases.The redox reactions are caused by propagation of oxidized (reduced) sites, generated at the electrode/copolymer interface, by electron transfer (electron hopping) reactions between mixed valent ferrocene/ferrocenium sites in the diffusion layer.Apparent electron diffusion coefficient for the electron transfer reactions, evaluated by potential step chronoamperometry, increases with increasing vinylferrocene composition in the copolymers.These copolymer/salt complexes are intrinsic redox conductors which exhibit appreciable ionic conductivity and redox activity by themselves without any fluid solvents and can be distinguished from conventional redox polymers.

MOESSBAUER STUDIES ON FERROCENE COMPLEXES. V. PROTONATION OF FERROCENYL KETONES

The structure of protonated ferrocenes has been investigated using 1H NMR and 57Fe Moessbauer spectroscopy.The ketones were fully protonated in CF3CO2H and in 70percent H2SO4/H2O.In more concentrated sulphuric acid < > 90percent H2SO4/H2O) rapid heteroannular sulphonation occurred.No evidence was obtained of any iron protonation in these systems.For the para substituted aromatic derivatives C5H5FeC5H4COC6H4X the NMR data indicates steric inhibition to resonance. 1,1′-Diketones are doubly protonated in strongly acid media (98percent H2SO4, CF3SO3H).Moessbauer data on the solid ketones showed decrease in quadrupole splitting (QS), relative to ferrocene itself, of about 0.12 mm s-1 for each successive acyl function added.For solid solutions of the protonated ketones in CF3CO2H this decrease (DeltaQS) was much larger at about 0.28 mm s-1.The results are interpreted as involving electron withdrawal from ring-based orbitals (epsilon1), rather than the iron-based orbitals (epsilon2).In the aromatic series, DeltaQS was significantly smaller for electron withdrawing substituents.

The hydrogen-bonded ferrocenylmethanol: Mediation of electron transfer for physically adsorbed glucose oxidase

The mechanism of electron transfer of ferrocenylmethanol through the self-assembled monolayer (SAM) of mercaptosuccinic acid (MSA) on gold was investigated. A key finding is that the hydrogen-bonded FcMeOH plays the role of a mediator in the electron transfer involving the physically adsorbed glucose oxidase at the MSA SAM surface. The space-conformation of the hydrogen-bonding between FcMeOH and MSA was obtained by computational methods. The FcMeOH interacts with MSA via the strong hydrogen bond with the short distance around 1.9 A at two different binding sites, approving the statements of hydrogen-bonding. The intermolecular hydrogen-bonding between redox mediator (FcMeOH) and the artificial self-assembled monolayer (MSA) is evident, and the mechanistic study of heterogeneous electron transfer kinetics is meaningful for the biosensor applications.

One-electron oxidation of ferrocenes by short-lived N-oxyl radicals. the role of structural effects on the intrinsic electron transfer reactivities

A kinetic study of the one electron oxidation of substituted ferrocenes (FcX: X = H, COPh, COMe, CO2Et, CONH2, CH2OH, Et, and Me2) by a series of N-oxyl radicals (succinimide-N-oxyl radical (SINO), maleimide-N-oxyl radical (MINO), 3-quinazolin-4-one-N-oxyl radical (QONO) and 3-benzotriazin-4-one-N-oxyl radical (BONO)), has been carried out in CH3CN. N-oxyl radicals were produced by hydrogen abstraction from the corresponding N-hydroxy derivatives by the cumyloxyl radical. With all systems, the rate constants exhibited a satisfactory fit to the Marcus equation allowing us to determine self-exchange reorganization energy values (lambdaNO/NO-) which have been compared with those previously determined for the PINO/PINO- and BTNO/BTNO- couples. Even small modification of the structure of the N-oxyl radicals lead to significant variation of the lambdaNO/NO- values. The lambdaNO/NO- values increase in the order BONO < BTNO < QONO < PINO < SINO < MINO which do not parallel the order of the oxidation potentials. The higher lambdaNO/NO- values found for the MINO and SINO radicals might be in accordance with a lower degree of spin delocalization in the radicals MINO and SINO and charge delocalization in the anions MINO- and SINO- due to the absence of an aromatic ring in their structure.

Exploration of the Smallest Diameter Tin Nanowires Achievable with Electrodeposition: Sub 7 nm Sn Nanowires Produced by Electrodeposition from a Supercritical Fluid

Electrodeposition of Sn from supercritical difluoromethane has been performed into anodic alumina templates with pores down to 3 nm in diameter and into mesoporous silica templates with pores of diameter 1.5 nm. Optimized deposits have been characterized using X-ray diffraction, scanning electron microscopy, and scanning transmission electron microscopy (bright field, high-angle annular dark field, and energy-dispersive X-ray elemental mapping). Crystalline 13 nm diameter Sn nanowires have been electrodeposited in symmetric pore anodic alumina. Direct transmission electron microscopy evidence of sub 7 nm Sn nanowires in asymmetric anodic alumina has been obtained. These same measurements present indirect evidence for electrodeposition through 3 nm constrictions in the same templates. A detailed transmission electron microscopy study of mesoporous silica films after Sn deposition is presented. These indicate that it is possible to deposit Sn through the 1.5 nm pores in the mesoporous films, but that the nanowires formed are not stable. Suggestions of why this is the case and how such extreme nanowires could be stabilized are presented.
