A simple approach for fabrication of microring electrodes

Herein we describe a simple approach for fabrication of microring electrodes by electroless plating a thin layer of gold on polycarbonate (PC) rods. First, the PC rod was exposed to UV light to generate carboxyl groups on the surface. After amination of the surface carboxyl groups by ethylenediamine, the rod was sequentially immersed in HAuCl4 and NaBH4 solutions to form a layer of gold nanoparticles. These gold nanoparticles then functioned as the catalytically active centers for electroless plating thin gold film on the PC rod surface. Finally, the rod surface was thoroughly covered by an insulating glue and fresh microring surface could be obtained easily by laterally cutting with a knife. The electrochemical behavior of thus prepared microring electrodes were characterized by cyclic voltammetry in hydroxymethylferrocene and H2SO4. The whole fabrication process is simple and economic, which can be carried out in ordinary laboratories. In addition, the results of electrocatalytic oxygen reduction demonstrated that the proposed microelectrode could be used as an alternative electrode materials for electrocatalysis and electroanalysis.

Novel dendrimers containing redox mediator: Enzyme immobilization and applications

In this study, new dendrimers with a ferrocene core were produced by means of a divergent method for the immobilization of the glucose oxidase enzyme (GOx). Pt(II)and Pt(IV)ions were attached to the terminal groups of dendrimers. Metal-containing dendrimers, [Fc(MGlu)2-Aph-Pt(II)]and [Fc(MGlu)2-Aph-Pt(IV)], were obtained using the ?template method? with aminophenol and Pt(II)/Pt(IV)cations. These compounds have been characterized by molar conductivity, magnetic susceptibility, FTIR, UV?Vis, 1H NMR and LC-MS methods. The GOx enzyme was immobilized on the Fc(MGlu)2, [Fc(MGlu)2-Aph-Pt(II)]and [Fc(MGlu)2-Aph-Pt(IV)]dendrimers, and the immobilized enzyme optimization parameters (substrate concentration, temperature, pH, reusability and storage capacity)were determined. Their Km (mM)and Vmax (mM.min?1)values were calculated from the Michaelis?Menten equation. The reusability of the immobilized glucose oxidase enzyme was investigated in an artificial urine medium. The research showed that [Fc(MGlu)2-Aph-Pt(II)]retains more than 61.23% of its initial activity after 10 successive cycles, which is a remarkable result.

Aminomethyl-substituted ferrocenes and derivatives: Straightforward synthetic routes, structural characterization, and electrochemical analysis

A variety of aminomethyl-substituted ferrocenes and the parent compounds (iminomethyl)ferrocenes, azaferrocenophanes, and diferrocenylamines can be selectively synthesized from reductive amination of 1,1?-diformylferrocene or formylferrocene. The optimized one- or two-step reactions have delivered 13 new compounds, isolated in 65-97% yields, which include tertiary (ferrocenylmethyl)amines and azaferrocenophanes by using NaBH(OAc)3 as a mild reducing agent and (iminomethyl)ferrocenes and secondary (ferrocenylmethyl)amines by using LiAlH4. X-ray structures of representative members of these ferrocene derivative families have evidenced the preferred conformation adopted by ferrocene backbones, in which surprisingly the steric hindrance is apparently not systematically minimized. 15N NMR measurements on aminomethyl-substituted ferrocenes and derivatives are provided for the first time, establishing benchmark values ranging from -330 to -305 ppm (nitromethane delta 0 ppm). The cyclic voltammetry of these species evidences two clearly distinct oxidation potentials related to the iron(II) center and the amino function. These aminomethyl-substituted ferrocenes are potentially valuable for further ortho-directed functionalization of ferrocene.

Functional and structural characterization of an ECF-type ABC transporter for vitamin B12

Vitamin B12 (cobalamin) is the most complex B-type vitamin and is synthetized exclusively in a limited number of prokaryotes. Its biologically active variants contain rare organometallic bonds, which are used by enzymes in a variety of central metabolic pathways such as L-methionine synthesis and ribonucleotide reduction. Although its biosynthesis and role as co-factor are well understood, knowledge about uptake of cobalamin by prokaryotic auxotrophs is scarce. Here, we characterize a cobalamin-specific ECF-type ABC transporter from Lactobacillus delbrueckii, ECF-CbrT, and demonstrate that it mediates the specific, ATP-dependent uptake of cobalamin. We solved the crystal structure of ECF-CbrT in an apo conformation to 3.4 A resolution. Comparison with the ECF transporter for folate (ECF-FolT2) from the same organism, reveals how the identical ECF module adjusts to interact with the different substrate binding proteins FolT2 and CbrT. ECF-CbrT is unrelated to the well-characterized B12 transporter BtuCDF, but their biochemical features indicate functional convergence.

Signal transduction and amplification through enzyme-triggered ligand release and accelerated catalysis

Signal transduction and signal amplification are both important mechanisms used within biological signalling pathways. Inspired by this process, we have developed a signal amplification methodology that utilises the selectivity and high activity of enzymes in combination with the robustness and generality of an organometallic catalyst, achieving a hybrid biological and synthetic catalyst cascade. A proligand enzyme substrate was designed to selectively self-immolate in the presence of the enzyme to release a ligand that can bind to a metal pre-catalyst and accelerate the rate of a transfer hydrogenation reaction. Enzyme-triggered catalytic signal amplification was then applied to a range of catalyst substrates demonstrating that signal amplification and signal transduction can both be achieved through this methodology.

Syntheses and properties of multiferrocenylated corannulenes

The syntheses and properties of corannulenes bearing different numbers and types of ferrocenyl groups are described. Six different monoferrocenylated corannulenes were synthesized, and the crystal structure of 1-corannulenyl-1?-(ferrocenyl)benzene was elucidated by single-crystal X-ray analysis. Further, diferrocenylated corannulenes bearing methyl or trifluoromethyl groups are reported. Buckybowls with four and five ferrocenyl substituents were synthesized from tetrabromocorannulene and the symmetrical pentachlorocorannulene. The molecular structure and nutshell-like crystal packing of a tetraferrocenylated corannulene was determined by single-crystal X-ray analysis. Additionally, all compounds presented herein were subjected to electrochemical and optical measurements in solution.

A double-driven photoelectrochemical cell

A novel photoelectrochemical cell consisting of a set of organic thin films which generate photocurrents in opposite directions was fabricated. The polythiophene film containing 5,10,15,20-tetraphenylporphyrin (TPP) and fullerene (C60) generated anodic photocurrents in the presence of ferrocene, while that containing TPP alone generated cathodic photocurrents under aerobic condition. The combination of these two film-modified electrodes showed a better cell performance than the simple sum of these two independent photoelectrochemical cells. A push-pull type, double-driven photoelectrochemical cell is proposed in this paper.

The conversion of 1,1?-dibromoferrocene to 1,2-dibromoferrocene: The ferrocene-chemist’s dream reaction

The conversion of 1,1?-dibromoferrocene to a range of 2-substituted bromoferrocenes is described. The products are useful in the preparation of a wide number of 1,2-disubstituted ferrocenes. This includes the preparation of 1,2-dibromoferrocene and 2-(diisopropylphosphino)bromoferrocene in what is a clean and simple synthesis. The synthesis may be carried out on a large scale and for the first time produces multigram quantities of these important precursor compounds. In addition the synthetic procedure may be modified to produce a new family of ferrocene-based tris-phosphine ligands such as bis(2-diphenylphosphinoferrocenyl)phenylphosphine.

Structure elucidation and DFT-study on substrate-selective formation of chalcones containing ferrocene and phenothiazine units. Study on ferrocenes, Part 17

By means of base-catalysed condensation of 1-acyl-/1,1?- diacylferrocenes (acylformyl or acetyl) with 3-formyl- and 3,7- diacetylphenothiazines a series of novel mono- and bis-chalcones were prepared. The enhanced reactivity of the enolate anions of the mono-chalcone intermediates relative to that of the enolates of the corresponding diacetyl-substituted precursor was interpreted by the electron-releasing effect of the ferrocenyl- or phenothiazinyl group present in the beta position of the enone subunit. The structures of the novel products were evidenced by IR, 1H and 13C NMR spectroscopy including 2D-COSY, 2D-HSQC and 2D-HMBC measurements.
