The synthesis, electrochemical, electronic, and cation sensing properties of multinuclear nitrogen-rich [2.2]- and [3.3]-mixed ferrocene and ruthenocene metallocenophanes are presented. Structural features of these new structural motifs are that the two redox organometallics fragments are linked by unsaturated nitrogen functionalities, for example, carbodiimide or aldimine, as well as the nitrogen atom is directly attached to the ruthenocene unit. The key bis(iminophosphorane) 3 is readily prepared by the Staudinger reaction between triphenylphosphine and 1,1?-diazidoruthenocene 2, which has been prepared from 1,1?- dilithioruthenocene and 2,4,6-trisopropylbenzenesulfonyl azide (trisyl azide). Subsequent aza-Wittig reactions of 3 with the appropriate carbonyl or thiocarbonyl compounds provided the opened ruthenocenebased isothiocyanate 4, and the closed carbodiimide 5 and aldimines 6 and 7. Spectroelectrochemical studies of carbodiimide 5 and aldimine 7 revealed the presence of low-energy bands in the near-IR region in the partially oxidized forms, at 1029 and 1481 nm, respectively, which indicate the existence of intramolecular charge transfer between the iron and the ruthenium centers. The experimental data and conclusions are supported by DFT computations. Moreover, the aldimine 7 behaves as a selective colorimetric chemosensor molecules for Zn2+ ions. The low-energy (LE) band of the absorption spectrum of this compound is red-shifted by 99 nm, only in the presence of Zn2+ ions. This change in the absorption spectrum is accompanied by a dramatic color change, which allows the potential for “naked eye” detection.

Diaphorase (DI) works as an effective catalyst for the electrochemical oxidation and reduction of NAD with the aid of several quinones or flavins as electron transfer mediators. The redox kinetics between DI and mediators have been expressed by a Butler-Volmer-type equation. NAD-dependent L-lactate dehydrogenase (LDH) catalyzing the redox reaction between L-lactate and pyruvate was coupled to the DI-catalyzed NAD redox system to achieve better understanding of mediated two-enzyme-linked bioelectrocatalysis with reversible characteristics. Under the conditions where the concentration polarization of NAD due to the DI-catalyzed electrochemical reaction is suppressed by the LDH reaction, the NAD concentration dependence of the catalytic current was expressed by an approximate equation involving the enzyme kinetics between DI and NAD. The suppression of the NAD concentration polarization is also useful to observe steady-state catalytic waves of an uphill reaction between DI and the mediator. The oxidation reaction involving the uphill electron transfer from L-lactate to NAD+ is susceptible to a inhibition from pyruvate due to the reversible characteristics of LDH. The present knowledge has led to the strategy to realize a two-way bioelectrocatalysis for the reduction of pyruvate and the oxidation of L-lactate. New potentiometry for the detection of the solution potential governed by the electrochemically inactive pyruvate/L-lactate redox couple has also been demonstrated based on the reversible characteristics of the DI-DLH-linked bioelectrocatalytic system.

Cucurbit[n]urils have been supported on graphene to develop sensitive and selective electrodes. The electrochemical response of modified electrodes containing graphene or graphene plus cucurbiturils has been studied for three probe molecules including hydroxymethylferrocene, ferrocyanide and methylviologen. It was found that the properties of these modified electrodes are derived from an increase in electron mobility and catalytic activity imparted by graphene and the selective complexation and molecular recognition due to cucurbit[n]urils. These properties of the graphene/cucurbit[n]urils modified electrodes have been applied for the electrochemical detection of relevant biomolecules as tryptophan at 0.69×10-7 M concentration.

Ferrocene and ferrocenium sites in radiofrequency plasma polymer films on Pt electrodes can be electrochemically oxidized and re-reduced in contact with a variety of electrolyte/solvent systems.When the electrochemical reaction is conducted under near-equilibrium conditions, cyclic voltammetric and chronopotentiometric waveshapes reflect the modulation of ferrocene and ferrocenium site activities by solvent swelling of the film.In water, ferrocene sites exhibit a phase-like (constant) activity during film oxidation, but in acetonitrile ferrocene site activity is proportional to fractional film oxidation.When the film oxidation or reduction is driven by a large potential step (avoiding film ohmic resistance effects), the rate of film reaction is controlled by Fickian diffusion of electrochemical charge through the film.In water, the product of charge diffusion constant and initial concentration of electroactive sites, D1/2C, is 2 X 10-8 mol/cm2 s1/2 for film oxidation and 1.4 X 10-8 mol/cm2 s1/2 for film re-reduction.The difference may be due greater film swelling in the oxidized state.The relationship of charge diffusion rates in redox polymer films on electrodes to their electrocatalytic reactions is discussed.

[1+1], [1+2], [2+1] or [3+1] acyclic and [1+1] or [2+2] cyclic Schiff bases (LALS), containing ferrocene moieties, have been prepared by reaction of formyl- or 1,1?-diformylferrocene and the appropriate amines. Formyl- and 1,1-diformylferrocene form respectively the acyclic [2+1] LW and [2+2]n LZ compounds by reaction with 1,4-diaminomethylbenzene. Similar compounds (LTLV) have been obtained by condensation of aminomethylferrocene and 2,6-diformylpyridine, 2,6-diformyl-4-chlorophenol and 3-methoxy-2-hydroxybenzaldehyde. By reduction of these compounds with NaBH4 the corresponding ferrocene-amine derivatives (L?) have been synthesized. All these compounds have been characterized by physico-chemical measurements (IR, NMR, Moessbauer spectroscopy and FAB mass spectrometry) and LH, derived by the condensation of ferrocene-aldehyde and 1,5-diamino-3-oxa-pentane, also by an X-ray structural determination. The X-ray analysis of crystals of LH, grown from a diethyl ether solution, shows that two independent molecules are present in the asymmetric unit; these two molecules are chemically equivalent with the ferrocenyl groups in the eclipsed form. The coordination ability of these compounds towards d metal ions as copper(II), nickel(II), platinum(II) and rhodium(III) was investigated; while the Schiff bases (L) may suffer hydrolysis, their reduced analogues (L?) form stable, well-defined complexes of the type M(L?)(Cl)n (n=2, 3). The Moessbauer spectra of the prepared compounds show signals with delta at 0.44 and DeltaEQ 2.30 mm s-1 for the Schiff bases LALS and 0.52 and 2.40 mm s-1 for the reduced analogues and hence may be diagnostic of the presence of Fe-CH=N- or Fe-CH2-NH- groups. The signals with delta at 0.51-0.55 and DeltaEQ at 2.34-2.38 mm s-1 for the Schiff bases LTLV, having Fe-CH2-N=CH groups, resemble those of the reduced analogues.

The super electrophilicity of a shelf-stable, easily prepared trifluoromethylthiolating reagent N-trifluoromethylthio-dibenzenesulfonimide 7 was demonstrated. Consistent with the theoretical prediction, 7 exhibits reactivity remarkably higher than that of other known electrophilic trifluoromethylthiolating reagents. In the absence of any additive, 7 reacted with a wide range of electron-rich arenes and activated heteroarenes under mild conditions. Likewise, reactions of 7 with styrene derivatives can be fine-tuned by simply changing the reaction solvents to generate trifluoromethylthiolated styrenes or oxo-trifluoromethylthio or amino-trifluoromethylthio difunctionalized compounds in high yields.

Biomolecules are integral constituents of living beings which regulate numerous biochemical functions of the body. Analysis of various small molecules (metabolites, neurotransmitters, amino acids, vitamins) and macromolecules (nucleic acids, proteins) is of prime importance in modern time due to increasing disbalance in natural metabolism of human body. Irregularities and alteration in concentration of biomolecules lead to different kinds of genetic, metabolic and cancerous diseases which have created a great requirement of highly sensitive, accurate and stable detection systems for their quick and specific screening. In this review, redox interactions of biomolecules at carbon based electrode interfaces have been discussed using voltammetry. It is divided into subsections, starting with an introduction into the field and a description of its current state. This is followed by a large section describing carbon nanomaterials (CNs) based voltammetric sensors for different small biomolecules and macromolecules.
