The functional dependence of the rate constants for self-exchange, kex, for a series of metallocene redox couples to solvent-induced variations in the nuclear frequency factor, nun, engendered by alterations in the longitudinal solvent relaxation time, tauL, are utilized to deduce values of the electronic matrix coupling element, H12, for electron exchange.The analysis exploits the sensitivity of the kex-tauL-1 dependence to the degree of reaction adiabaticity and hence H12 for a given electron-exchange reaction.Six metallocene couples are examined:Cp2Co+/0, Cp2Fe+/0 (Cp = cyclopentadienyl), the decamethyl derivatives Cp’2Co+/0 and Cp’2Fe+/0 scrutinized previously, with additional solvent-dependent kex values for (carboxymethyl)cobaltocenium-(carboxymethyl)cobaltocene and (hydroxymethyl)ferrocenium-(hydroxymethyl)ferrocene .Kinetic data are examined in 15 solvents, including 11 “Debye” solvents for which it is anticipated that nun <*> tauL-1.Corrections to kex for the solvent-dependent variations in the barrier height were obtained by corresponding measurements of the optical electron-transfer energies for the related binuclear complex biferrocenylacetylene, yielding “barrier-corrected” rate constants, k’ex.The k’ex-tauL-1 dependencies, as well as the kex values in a given solvent, are markedly dependent on the redox couple.The log k’ex-log tauL-1 plots for the most facile couple, Cp’2Co+/0, exhibit slopes approaching unity for smaller tauL-1 values.The less facile couples yield smaller slopes, diminishing in the same sequence that k’ex decreases in a given solvent: Cp’2Co+/0 >Cpe2Co+/0 > Cp2Co+/0 >/= Cp’2Fe+/0 > Cp2Fe+/0 >/= HMFc+/0.These findings are consistent with H12 decreasing in the same order.Comparison of such rate-solvent friction dependencies with corresponding plots calculated using a combined solvent friction-electron tunneling model yields the following approximate values of the matrix coupling element for reactant “closest approach”, H012 (kcal mol-1): Cp’2Co+/0, 1.0; Cpe2Co+/0, 0.5-1.0; Cp2Co+/0, 0.5; Cp’2Fe+/0, 0.2; Cp2Fe+/0, 0.1; HMFc+/0, 0.075.Reasonable concordance is seen with recent theoretical estimates of H012 for Cp2Co+/0 and Cp2Fe+/0.The relationship between H012 and metallocene electronic structure is briefly discussed.The analysis also enables effective solvent relaxation times for adiabatic barrier crossing in non-Debye media, including primary alcohols, to be extracted.

The catalytic hydrogenolysis of 1,2-disubstituted ferrocenes having planar chirality and functional groups such as carboxyl (including ester) or tertiary amino proceeds under mild conditions (1 atm of H2, Pd/C, CF3COOH, 50 deg C) with the retention of functional groups in the cyclopentane products.Stereosectivity has been observed for the examples investigated, the diastereomeric ratio, trans: cis being close to 4:1, but optically inactive products are formed the enantiomeric ferrocenes.In contrast, hydrogenolysis of enantiomeric alpha-(N,N-dimethylamino)ethylferrocene gives an optically active alpha-(N,N-dimethylamino)ethylcyclopentane with retention of configuration at the alpha-carbon, whose bonds are not affected during the hydrogenolysis.

The visible absorption spectra and reduction potentials of 11 ferrocenes containing electron-withdrawing substituents were determined in an N-n-butylpyridinium chloride-aluminum chloride molten salt. When the substituent(s) on the cyclopentadienyl ring(s) of ferrocene were varied, the reduction potential was caused to range over 1.25 V, and the wavelength for maximum absorption of visible light was varied by nearly 200 nm. These changes are greater than have been observed for similar ferrocenes in other nonaqueous solvents. Evidence is presented for specific interactions of particular ferrocenes with the molten salt.

By activating Si-H bonds, poly(hydromethylsiloxane) can be covalently bound in a first step to various metal or polymer surfaces. In a second step, unreacted Si-H bonds can be brought to react with organic compounds having adequate functional groups such as double or triple bonds, carbonyl or hydroxyl groups. This scheme is used to bind biorecognition groups to solids. The novel concept is demonstrated by attaching a newly synthesized biotin derivative to Au. It is shown that the immobilized biotin is capable of binding streptavidin.

Porous crystals are excellent materials with potential spatial functions through molecular encapsulation within the pores. Co-encapsulation of multiple different molecules further expands their usability and designability. Herein we report the simultaneous arrangement of up to three different guest molecules, TTF (tetrathiafulvalene), ferrocene, and fluorene, on the pore surfaces of a porous crystalline metal-macrocycle framework (MMF). The position and orientation of adsorbed molecules arranged in the pore were determined by single-crystal X-ray diffraction analysis. The anchoring effect of hydrogen bonds between the hydroxy groups of the guest molecules and inter-guest cooperation and competition are significant factors in the adsorption behaviors of the guest molecules. This finding would serve as a design basis of multicomponent functionalized nanospaces for elaborate reactions that are realized in enzymes.

Pnictogens are an intensively studied group of monoelemental two-dimensional materials. This group of elements consists of phosphorus, arsenic, antimony, and bismuth. In this group, the elements adopt two different layered structural allotropes, orthorhombic structure with true van der Waals layered interactions and rhombohedral structure, where covalent interactions between layers are also present. The orthorhombic structure is well known for phosphorus and arsenic, and the rhombohedral structure is the most thermodynamically stable allotropic modification of arsenic, antimony, and bismuth. Due to the electronic structure of pnictogen layers and their semiconducting character, these materials have huge application potential for electronic devices such as transistors and sensors including photosensitive devices as well as gas and electrochemical sensors. While photodetection and gas sensing applications are often related to lithography processed materials, chemical sensing proceeds in a liquid environment (either aqueous or non-aqueous) and can be influenced by surface oxidation of these materials. In this review, we explore the current state of pnictogen applications in sensing and electronic devices including transistors, photodetectors, gas sensors, and chemical/electrochemical sensors.

In a document type is Article, and a compound is mentioned, 1273-86-5, name is Ferrocenemethanol, introducing its new discovery.

A comparison of the analytical characteristics of two tyramine biosensors, based on graphene oxide (GRO) and polyvinylferrocene (PVF) modified screen-printed carbon electrodes (SPCE), is reported. Diamine oxidase (DAOx) or monoamine oxidase (MAOx) was immobilized onto the PVF/GRO modified SPCE to fabricate the biosensors. Surface characteristics and electrochemical behaviour of the modified SPCEs were investigated by atomic force microscopy (AFM), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and cyclic voltammetry (CV). Electrode surface composition and experimental variables such as pH and working potential were optimized in order to ensure a high performance. Under optimum experimental conditions, both DAOx/PVF/GRO/SPCE and MAOx/PVF/GRO/SPCE biosensors exhibited wide linear dynamic ranges for tyramine from 9.9×10?7 to 1.2×10?4 M and from 9.9×10?7 to 1.1×10?4 M, respectively. MAOx/PVF/GRO/SPCE biosensor showed higher sensitivity (11.98 muA mM?1) for tyramine determination than the DAOx/PVF/GRO/SPCE biosensor (7.99 muA mM?1). The substrate specifity of the biosensors to other biogenic amines namely histamine, putrescine, spermine, spermidine, tryptamine, beta-phenylethylamine and cadaverine was also investigated. The developed biosensors were successfully used for tyramine determination in cheese sample.

In lab-on-a-chip electroanalysis, the mass transfer of electroactive species towards the electrode surface limits the detection performance due to the difficulty in applying external convection. In this study, we proposed to integrate miniature acoustic resonator, fabricated by microelectrochemical system, within on-chip electroanalytical platform to improve electrochemical process. Gold film electrochemical sensor chip and acoustic resonator were assembled face-to-face with a polydimethylsiloxane chamber in between. Cyclic voltammetric (CV) responses of ferrocenemethanol were tested under actuation of miniature acoustic resonator at various powers. Resonator’s actuation results in sigmoidal CV curves and the diffusion limited current increases with the rise of applied power on resonator. The advantages of miniature acoustic resonator, including submillimeter small size, mass fabricability, low cost, low energy consumption, as well as outstanding performance towards enhancing electrochemical process, will strongly contribute to the development of highly-sensitive compact sono-electroanalytical devices.
