Size-dependent efficiency of electron transfer at suspended ferrocenyl jumbo particles

Ferrocenylmethanol acrylate (FcMA)-immobilized polystyrene latex particles were synthesized by copolymerizing FcMA and styrene in the presence of polystyrene latex suspensions with eight different diameters ranging from 0.084 to 1.7 mum. The amounts of the ferrocenyl moiety loaded on one particle were proportional to the radii, a. The proportionality suggests the uniform distribution of the ferrocenyl moiety over the particle, of which concentration was 0.18 M. The aqueous suspensions, which were stable in the presence of a surfactant, exhibited reversible voltammetric waves for the ferrocenyl moiety. The peak current was controlled by diffusion of the latex particles. The efficiency of the reaction was obtained from the ratio of the observed current to the theoretical one which was estimated from the number of the ferrocenyl moieties and the diffusion coefficient of the particle by the Stokes-Einstein relation. The ratio was proportional to a-0.47, whereas it might be a0 for an ideal particle without any size effect. This relation was explained in terms of the contribution of rotational diffusion of redox particles.

The reactions of acylferrocenes with samarium diiodide: Reduction, deoxygenation, reductive coupling and rearrangement

Acylferrocenes reacted with samarium diiodide in the presence of water to give the corresponding (alpha-hydroxyalkyl)ferrocenes or alkylferrocenes depending on the reaction time and temperature. On treatment with samarium diiodide in the absence of water, ferrocenecarbaldehyde underwent a reductive coupling to give pinacols, whereas acetylferrocene yielded 3,3-diferrocenyl-2-butanone and 2,3-diferrocenyl-2-butene via the subsequent rearrangement and deoxygenation.

Scanning electrochemical microscope studies of dye regeneration in indoline (D149)-sensitized ZnO photoelectrochemical cells

A scanning electrochemical microscope (SECM) in the feedback and generation-collection modes was used to investigate the regeneration of photoexcited dye cations at the semiconductor/electrolyte interface in a dye-sensitized solar cell (DSSC) based on ZnO/D149. An effective dye regeneration rate constant kox of 9.55 ¡Á 107 cm 9/2 mol-3/2 s-1 was obtained from feedback mode experiments at different wavelengths and light intensities on ZnO/D149 electrodes. Illuminated regions of the dye-sensitized electrodes could be differentiated from non-illuminated regions by local imaging in SECM generation-collection experiments with I- as redox mediator. We also report SECM feedback measurements on non-illuminated dye-sensitized electrodes to investigate the electron transfer kinetics of dissolved redox couples at the underlying FTO substrate.

Mechanoelectrochemistry of soft electroactive materials via surface-tracked scanning electrochemical microscopy

Real time measurement of time-correlated ion transport and volumetric changes in electroactive materials is necessary to understand and model mechanoelectrochemistry. Reversible reduction and oxidation of soft electroactive materials such as conducting polymers result in the deformation of the material due to ion transport into and out of the polymer backbone. In cells, ion transport and volumetric expansion are collectively responsible for homeostasis that is essential for life functions and hence, mechanoelectrochemistry of cells is essential to understand cell and developmental biology. The characterization methods required to investigate mechanoelectrochemistry require nanoscale spatial resolution for the imaging of a redox active site in a polymer or a small group of transmembrane proteins in a single cell. Towards this goal, we present an imaging technique using scanning electrochemical microscopy (SECM) hardware with shear-force (SF) feedback for high bandwidth mechanoelectrochemistry characterization. In this proceedings article, we demonstrate this technique referred to as surface-tracked scanning electrochemical microscopy technique (ST-SECM) that is realized by measuring the structural feedback of the glass electrode to position the electrode in 10s of nanometers above the surface of a polypyrrole membrane doped with dodecylbenzenesulfonate (PPy(DBS)). Two ultra-microelectrodes of controlled dimensions (of 20 mum and 30 mum glass diameter) were fabricated using a hydrofluoric acid etching technique and were used to generate a spatially correlated ion storage map of PPy(DBS). We compare the developed technique to a three-dimensional discrete scan over the surface and show that a ST-SECM technique produces a higher resolution and takes approximately 200 fewer minutes as compared to the conventional technique.

Synthesis of ferrocenylmethylidene and arylidene substituted camphane based compounds as potential anticancer agents

Herein is described the synthesis of (+)-camphor derivatives containing sulfonamide groups, ferrocenylmethylidene or arylidene moieties. The obtained derivatives were tested against seven human cancer cells lines, namely BV-173, K-256a, NB-4, A549, H1299, MCF-7, and MDA-MB231, and two normal human cell lines, HEK293 and HUVEC, in order to determine their activity against malignant cells. Some of them exhibit IC50 values below 10 muM in at least one of the cancer cell lines. Ferrocenylmethylidene ketone 16 can be outlined as the most potent and selective in the current study (IC50 for cancer cells-up to 4.0 muM; IC50 for HEK293 and HUVEC-68 and 69 muM, respectively). There is a clear trend showing that the presence of a conjugated ferrocenylmethylidene group is essential for the cytotoxicity, however different sulfonamide substituents and derivatization of the carbonyl group can modify the activity. Thus, this class of compounds could have good prospects for further structural optimisation.

Disposable biosensors for determination of biogenic amines

This work reports monoamine oxidase (MAO)/horseradish peroxidase (HRP) and diamine oxidase (DAO)/horseradish peroxidase (HRP) based biosensors using screen-printed carbon electrodes for the determination of biogenic amines (BA). The enzymes have been covalently immobilized onto the carbon working electrode, previously modified by an aryl diazonium salt, using hydroxysuccinimide and carbodiimide. The detection has been performed by measuring the cathodic current due to the reduction of the mediator hydroxymethylferrocene at a low potential, 250. mV vs screen-printed Ag/AgCl reference electrode. The experimental conditions for the enzymes immobilization, as well as for the main variables that can influence the chronoamperometric current have been optimized by the experimental design methodology. Under these optimum conditions, the disposable biosensors have been characterized. A linear response range from 0.2 up to 1.6 muM and from 0.4 to 2.4 muM of histamine was obtained for DAO/HRP and MAO/HRP based biosensors, respectively. The biosensor construction was highly reproducible, yielding relative standard deviations of 10% and 11% in terms of sensitivity for DAO/HRP and MAO/HRP based biosensors, respectively. The capability of detection, 0.18 ¡À 0.01 muM in the case of DAO/HRP and 0.40 ¡À 0.04 muM (alpha=0.05 and beta=0.005) for MAO/HRP based biosensors, and the biosensor sensitivity towards different BA has also been analyzed. Finally, the developed biosensors have been applied to the determination of the total amine content in fish samples.

Stereospecific synthesis, structural characterisation and resolution of 2-phospha[3]ferrocenophane derivatives – A new chiral scaffold

The first 2-phospha[3]ferrocenophanes containing stereogenic carbon atoms in the three-atom bridge have been synthesised from phenylphosphane by stereospecific ring-closing phosphanation reactions. Either alpha-substituted 1,1?-bis-(hydroxymethyl)ferrocenes or the corresponding 2-oxa-[3]ferrocenophanes have been used as diastereomerically pure starting materials. The resolution of 1,2,3-triphenyl-[2]phosphaferrocenophane has been achieved by chromatographic separation of the diastereomeric adducts of a chiral cyclopalladate complex. The X-ray crystal structures of two 2-phospha[3]ferrocenophane-borane complexes are also reported. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

Impact of Plasmonic Photothermal Effects on the Reactivity of Au Nanoparticle Modified Graphene Electrodes Visualized Using Scanning Electrochemical Microscopy

Atomically thin graphene electrodes enable the modulation of interfacial reactivity by means of underlying substrate effects. Here we show that plasmonic excitation of microscopic arrays composed of 50 nm Au nanoparticles situated underneath a graphene interface results in localized enhancements on the electrochemical readout. We used scanning electrochemical microscopy (SECM) in the feedback and H2O2 collection modes to identify the role of the generated plasmons on the electrochemical response. Using electrochemical imaging, supported by finite-element method simulations, we confirmed that a temperature rise of up to ?30 K was responsible for current enhancements observed for mass transfer- limited reactions. On single-layer graphene (SLG) we observed a shift in the onset of H2O2 generation which we traced back to photothermal induced kinetic changes, raising ko? from 1.1 ¡Á 10-8 m/s to 2.2 ¡Á 10-7 m/s. Thicker 10-layer graphene electrodes displayed only a small kinetic difference with respect to SLG, suggesting that photothermal processes, in contrast to hot carriers, are the main contributor to the observed changes in interfacial reactivity upon illumination. SECM is demonstrated to be a powerful technique for elucidating thermal contributions to reactive enhancements, and presents a convenient platform for studying sublayer and temperature-dependent phenomena over individual sites on electrodes.
