Oxidative purification of halogenated ferrocenes

We report the large scale syntheses and ‘oxidative purification’ of fcI2, fcBr2 and FcBr (fc = ferrocene-1,1?-diyl, Fc = ferrocenyl). These valuable starting materials are typically laborious to separate via conventional techniques, but can be readily isolated by taking advantage of their increased E1/2 relative to FcH/FcX contaminants. Our work extends this methodology towards a generic tool for the separation of redox active mixtures.

DNA interaction, antioxidant, and in vitro antitumor activity of binuclear ruthenium(III) complexes of benzothiazole-substituted ferrocenyl thiosemicarbazones

In our search for new anticancer drugs, a series of binuclear ruthenium(III) thiosemicarbazone complexes of the type [RuCl 2(EPh3)]2L (where E = P/As; L = binucleating monobasic tridentate thiosemicarbazone ligand) have been synthesized. Structural features were determined by various physico-chemical and spectral techniques. The interactions of these complexes with CT-DNA were investigated by absorption spectral study, indicates that the binuclear ruthenium(III) complexes form adducts with DNA and has intrinsic binding constant in the range of 1.0 ¡Á 104-7.9 ¡Á 104 M-1. The free radical scavenging activity of binuclear ruthenium(III) complexes have been determined by their interaction with the stable DPPH free radical.

Incorporation of metallocenes into the channel structured Metal-Organic Frameworks MIL-53(Al) and MIL-47(V)

A selection of metallocene inclusion compounds with channel structured MOFs (MOF = Metal-Organic Framework) were obtained via solvent-fee adsorption of the metallocenes from the gas-phase. The adsorbate structures ferrocene 0.5@MIL-53(Al) (MIL-53(Al) = [Al(OH)(bdc)]n with bdc = 1,4-terephthalate), ferrocene0.25@MIL-47(V) (MIL-47(V) = [V(O)(bdc)]n), cobaltocene0.25@MIL-53(Al), cobaltocene0.5@MIL-47(V), 1-formylferrocene0.33@MIL-53(Al) , 1,1?dimethylferrocene0.33@MIL-53(Al), 1,1?- diformylferrocene0.5@MIL-53(Al) were determined from powder X-ray diffraction data and were analyzed concerning the packing and orientation of the guest species. The packing of the ferrocene guest molecules inside MIL-47(V) is significantly different compared to MIL-53(Al) due to the lower breathing effect and weaker hydrogen bonds between the guest molecules and the host network in the case of MIL-47(V). The orientation of the metallocene molecule is also influenced by the substituents (CH3 and CHO) at the cyclopentadienyl ring and the interaction with the bridging OH group of MIL-53(Al). The inclusion of redox active cobaltocene into MIL-47(V) leads to the formation of a charge transfer compound with a negatively charged framework. The reduction of the vanadium centers is stoichiometric. The resulting material is a mixed valence compound with a V3+/V4+ ratio of 1:1. The new compounds were characterized via thermal gravimetric analysis, infrared spectroscopy, solid state NMR, and differential pulse voltammetry. Both systems are 1D-channel pore structures. The metallocene adsorbate induced breathing effect of MIL-53(Al) is more pronounced compared to MIL-47(V), this can be explained by the different bridging groups between the MO6 clusters.

Addition of redox additive to ionic liquid electrolyte for high-performance electrochemical capacitors of n-doped graphene aerogel

To enhance the specific energy of electrochemical capacitors, several methods have been introduced including complex electrode modification as well as asymmetric cell development. Herein, an alternative approach to enhance both specific energy and power of N-doped reduced graphene oxide aerogel electrochemical capacitor via the introduction of hybrid redox electrolyte is proposed. The electrochemical properties of the hybrid electrolyte composing of 1-butyl-1-methylpyrrolidinium dicyanamide ionic liquid with 100mMferrocenemethanol redox additive were studied via cyclic voltammetry, galvanostatic charge-discharge, and electrochemical impedance spectroscopy. The combination between a unique nanostructure of N-doped reduced graphene oxide aerogel and novel hybrid electrolyte results in an excellent specific capacitance and specific energy of 112.1 F g-1 and 34.2 Wh kg-1, respectively, as compared to 76.7 F g-1 and 23.5 Wh kg-1 of the neat 1-butyl-1-methylpyrrolidinium dicyanamide electrolyte. The remarkable improvements can be explained by the emerging of the Faradaic-redox activity of the ferrocene methanol at the electrode-electrolyte interface. This simple approach could demonstrate another feasible route to improve the performance of ionic liquid-based electrochemical capacitors.

Syntheses, crystal structures and electrochemical studies of bi- and trimetallic conjugated ferrocene-based complexes

New bisferrocenyl pyridine, nitrile and nitro terminated compounds have been obtained by Wittig reactions. The coordination capabilities of the nitrile and pyridine compounds have been proved by coordination to M(CO)5 fragments, M being Cr, Mo or W. The electrochemical properties of the compounds have been studied by means of cyclic voltammetry, showing an effective electronic coupling between the two ferrocenyl fragments. The crystal structures of several of the described complexes are reported, showing that, in all cases, the syn conformation on the 1,1? bis-substituted ferrocene is preferred over the anti one.

Stochastic amperometric fluctuations as a probe for dynamic adsorption in nanofluidic electrochemical systems

Adsorption of analyte molecules is ubiquitous in nanofluidic channels due to their large surface-to-volume ratios. It is also difficult to quantify due to the nanometric scale of these channels. We propose a simple method to probe dynamic adsorption at electrodes that are embedded in nanofluidic channels or which enclose nanoscopic volumes. The amperometric method relies on measuring the amplitude of the fluctuations of the redox cycling current that arise when the channel is diffusively coupled to a bulk reservoir. We demonstrate the versatility of this new method by quantifying adsorption for several redox couples, investigating the dependence of adsorption on the electrode potential and studying the effect of functionalizing the electrodes with self-assembled monolayers of organothiol molecules bearing polar end groups. These self-assembled monolayer coatings are shown to significantly reduce the adsorption of the molecules on to the electrodes. The detection method is not limited to electrodes in nanochannels and can be easily extended to redox cycling systems that enclose very small volumes, in particular scanning electrochemical microscopy with nanoelectrodes. It thus opens the way for imaging spatial heterogeneity with respect to adsorption, as well as rational design of interfaces for redox cycling based sensors.

Reorganization energies of diprotonated and saddle-distorted porphyrins in photoinduced electron-transfer reduction controlled by conformationaldistortion

Kinetics of photoinduced electron transfer from a series of electron donors to the triplet excited states of a series of nonplanar porphyrins, hydrochloride salts of saddle-distorted dodecaphenylporphyrin ([H 4 DPP]Cl 2 ), tetrakis(2,4,6-trimethylphyenyl)porphyrin ([H 4 TMP]Cl 2 ), tetraphenylporphyrin ([H 4 TPP]Cl 2 ), and octaphenylporphyrin ([H 4 OPP]Cl 2), were investigated in comparison with those of a planar porphyrin, zinc [tetrakis(pentafluorophenyl)]porphyrin [Zn(F 20 TPP)(CH 3 CN)], in deaerated acetonitrile by laser flash photolysis. Theresulting data were evaluated in light of the Marcus theory of electron transfer, allowing us to determine reorganization energies of electron transfer to be 1.21 eV for [H 4 TMP]Cl 2 ,1.29 eV for [H 4 TPP]Cl 2 , 1.45 eV for [H 4 OPP]Cl 2 , 1.69 eV for [H 4 DPP]Cl 2 , and 0.84 eV for [Zn(F 20 TPP)(CH 3 CN)]. The reorganization energies exhibited a linear correlation relative to the out-of-plane displacements, which represent the degree of nonplanarity. The rate of electron-transfer reduction of diprotonated porphyrins is significantly slowed down byconformational distortions of the porphyrin ring. This indicates that t he reorganization energy of electron transfer is governed by structural change, giving a larger contribution of inner-sphere bond reorganizationenergy rather than outer-sphere solvent reorganization energy.

Suppressed photoelectrochemistry at carbon-surface-modified mesoporous TiO2 films

Cellulose nano-whiskers or nanocrystals are used as a carbon source in a vacuum graphitisation process to surface-modify nano-TiO2 and influence its photoreactivity. In sharp contrast to bulk carbon-modified TiO2 materials, introducing cellulose in a controlled way, i.e., a layer-by-layer deposition process, allows thin film materials to be created with low graphite content, but with strongly suppressed responses to light. The effect is explained by highly effective surface recombination and demonstrated for the I3-/I- redox system in acetonitrile and for the photo-oxidation of acetate in aqueous media.

An electrogenerated chemiluminescent biosensor based on a g-C3N4-hemin nanocomposite and hollow gold nanoparticles for the detection of lactate

In this article, a new electrochemiluminescent (ECL) biosensor based on a g-C3N4-hemin nanocomposite and hollow gold nanoparticles (HGNPs) was constructed to detect lactate. Firstly, the g-C3N4 nanosheets were prepared through ultrasonication-assisted liquid exfoliation of bulk g-C3N4, which was obtained through polymerizing melamine under 600C. Then, the nanocomposites of g-C3N4 nanosheets and hemin were prepared to modify a glassy carbon electrode. Subsequently, HGNPs were self-assembled onto the electrode for adsorbing lactate oxidase to achieve a lactate biosensor. Due to the excellent catalytic effect of g-C3N4-hemin and HGNPs on the luminol/H2O2 ECL system, the as-prepared biosensor exhibited a good response performance to lactate with a linear range of 1.7 ¡Á 10-8 to 5.0 ¡Á 10-4 M and a detection limit of 5.5 ¡Á 10-9 M. In addition, the prepared ECL biosensor exhibited satisfying reproducibility and stability. The g-C3N4-hemin nanocomposite might have great potential application in a luminol/H2O2 ECL system.

Oxygen Reduction at Carbon-Supported Lanthanides: TheRole of the B-Site

The kinetics of the oxygen reduction reaction (ORR) at carbon-supported transition-metal oxides in alkaline solutions is systematically investigated as a function of the nature of the B-site. The study is focused on LaBO3 (B=Cr, Co, Fe, Mn and Ni) nanoparticles synthesized by using an ionic-liquid route, offering fine control over phase purity and composition. Activity towards the ORR was compared with the commercial Pt/Etek catalyst. Detailed electrochemical analysis employing a rotating ring-disk electrode provides conclusive evidence that the carbon support plays an important contribution in the faradaic responses. Decoupling the contribution of the carbon support uncovers that the reactivity of LaMnO3 towards the four-electron ORR pathway is orders of magnitude higher than that for the other lanthanides. We rationalize these observations in terms of changes in the redox state at the B-site close to the formal oxygen reduction potential.
