A new form of high surface area bioelectrode, based on nanofibers of electrospun gold with immobilized fructose dehydrogenase, was developed. The gold fibers were prepared by electroless deposition of gold nanoparticles on an electrospun poly(acrylonitrile)-HAuCl4 fiber. The material was characterized using electron microscopy, XRD and BET, as well as cyclic voltammetry and biochemical assay of the immobilized enzyme. The electrochemical surface area of the gold microfibers was 0.32±0.04m2/g. Fructose dehydrogenase was covalently coupled to the gold surface through glutaraldehyde crosslinks to a cystamine monolayer. The enzyme exhibited mediated electron transfer directly to the gold electrode and catalytic currents characteristic of fructose oxidation in the presence of a ferrocene methanol mediator were observed. The limit of detection of fructose was 11.7muM and the KM of the immobilized enzyme was 5mM. The microfiber electrode was stable over 20 cycles with a 3.05% standard deviation. The response time of the sensor was less than 2.2s and reached half maximum value within 3.6s. The sensor was proven to be accurate and precise in both serum and popular beverages sweetened with high fructose corn syrup. The addition of glucose isomerase enabled the sensor to perform with glucose, thus expanding the available analyte selection for the sensor.

Air-stable primary phosphines were photopolymerized using phosphane-ene chemistry, the phosphorus analogue of the thiol-ene reaction, to fabricate a completely new class of polymer networks. It was demonstrated that the tunable thermal and physical properties accessible using thiol-ene chemistry could also be achieved using an analogous phosphane-ene reaction. At the same time, the presence of the 31P nucleus that is easily observed using NMR spectroscopy allowed the chemical structures of the networks to be directly probed using solid state NMR spectroscopy. Following its incorporation into the network, phosphorus offers the distinct difference and advantage of being able to undergo a diverse array of further derivatization to afford functional materials. For example, the networks were demonstrated to serve as effective oxygen scavengers and to bind transition metals (e.g., Pd). By using the air stable ferrocenyl phosphine (FcCH2CH2)PH2, redox-active networks were produced and these materials could be pyrolyzed to yield magnetic ceramics. Overall, this demonstrates the promise of phosphane-ene chemistry as an alternative to thiol-ene systems for providing functional materials for a diverse range of applications.

A series of ferrocenyl-arene dyads, Fc-C=C-Ar, trans-Fc-CH=CH-Ar, and Fc-CH=CH-CH=CH-Ar (Ar = phenyl, 1-naphthyl, 2-naphthyl, 9-phenanthryl, 9-anthryl, 1-pyrenyl, 3-perylenyl) have been synthesized. Their structures and spectroelectrochemical properties are discussed. The molecular structures of several have been determined by X-ray diffraction and the observed structures compared with global free-energy minimized calculated structures. In the solid state all ethynyl dyads have the aromatic ring orthogonal to the ferrocenyl cyclopentadienyl rings, whereas calculations predict a coplanar orientation. Calculated and observed structures agree for the ethenyl dyads with the rings orthogonal and coplanar for the anthryl and pyrenyl dyads, respectively. In most cases the solid-state structures are stabilized by offset pi-stacking interactions between the polycyclic hydrocarbon rings. The two bands in the electronic spectra of the neutral dyads are due to the individual aryl and ferrocenyl end-groups. Upon oxidation at the [Fc]+/0 couple, the ferrocenyl transition is replaced by LMCT bands at lower energy and a new weak band in the NIR assigned to a Fc+ ?aryl transition; these assignments are supported by resonance Raman spectra, and the energy of the Fc+? aryl transition correlates with the ionization energy of the aryl group. These are therefore electrochromic dyads.

A new low-cost reversible Glass-NOA-PDMS microfluidic device was designed for the study of recovery yield of precious metals present in acid media mimicking leach liquors for long-term recycling objectives. It offers the unique advantage of allowing easy washing of the microchannel and renewal of the electrode surface by simply repositioning the microband electrodes which allows this type of device to have a relatively much longer lifespan than irreversibly closed ones. It consists in a re-useable microchip with four graphite microbands electrodes, prepared by screen printing, to set-up an original amperometric device for both depletion and yield quantification. One upstream working electrode is devoted to the depletion of the metallic ions through their electrolysis by electrodeposition while the second downstream working microelectrode is used as real-time detection electrode to evaluate the depletion efficiency. The dimensions of the depletion electrode and of the channel were optimized thanks to numerical simulations for a given range of flow velocities. First, the performances of the device were assessed experimentally according to flow rate and applied potential under continuous flow, and then compared to theoretical predictions using an electrochemical probe, ferrocenemethanol. The proof of concept was then demonstrated for precious metal, by electroreduction of Pd(II) and Au(III) from acidic leach liquors under continuous flow, with a depletion yield of up to 89% and 71% respectively.

Highly enantioselective kinetic resolution of racemic planar-chiral metallocenylphosphine sulfides was realized by the molybdenum-catalyzed asymmetric ring-closing metathesis reaction with the krel values of up to 147. The enantiomerically enriched 1,4-but-2-enylene-bridged ferrocenylphosphine sulfides thus obtained could be purified to enantiomerically pure forms by simple recrystallization from hot methanol, and subsequent reduction of the phosphine sulfides provided the corresponding planar-chiral phosphines with retention of the enantiomeric homogeneity. This is a rare example of preparing planar-chiral ferrocenylphosphines by catalytic asymmetric reactions. The single-enantiomer planar-chiral ferrocenylphosphines were applied as chiral ligands in the rhodium-catalyzed asymmetric 1,4-addition reaction (the Hayashi-Miyaura conjugate addition reaction) of phenylboronic acid to 2-cyclohexenone to show excellent enantioselectivity and high yields. The NMR studies clarified that the butenylene-bridged ferrocenylphosphine coordinated to a rhodium(I) cation in a monodentate fashion and an interaction of the bridging olefin moiety to the rhodium atom was not detected.

An efficient procedure for the enantioselective synthesis of beta-ferrocenyl-beta-amino alcohols, a new class of central chiral ferrocene derivatives suitable for the elaboration of auxiliaries and ligands for asymmetric synthesis, is described. Key steps of the method are the catalytic asymmetric dihydroxylation of 1-ferrocenyl alkenes and the regio- and stereoselective azide substitution of the hydroxyl group adjacent to the ferrocene moiety. The stereochemistry of the substitution step has been established by X-ray diffraction analysis of a cyclic derivative. The first catalytic enantioselective synthesis of a beta-ferrocenyl-beta-amino acid derivative is also disclosed.
