Covalent layer-by-layer type modification of electrodes using ferrocene derivatives and crosslinkers

A series of mono-substituted ferrocenes (Fecp₂R, R = CONHCH₂N(C₂H₄NH₂)₂ (4), R = CH₂NHCH₂N(C₂H₄NH₂)₂ (5)) and di-substituted ferrocenes (Fe(cpR)₂, R = COF (3)) have been prepared, with 4 and 5 representing new compounds. The ferrocenes were grown layer-by-layer on metal oxide electrodes and crosslinked. The underlying principle of synthesis is based on repetitive and fast amide forming reactions between trimesic acid chloride (2) or Fe(cpCOF)₂ (3) and tris(2-aminoethyl)amine (6), or one of the amine-substituted ferrocenes 4 or 5 on a 3-aminopropyl triethoxysilane (APS) (1) modified ITO, FTO or ATO electrode. Linear growth of the films electroactivity with the number of cascade steps is observed for up to 12 cascade steps yielding 1.1 × 10⁻⁸ ferrocene centers/cm² on a flat ITO electrode, whereas 3 cascade steps yield 2.2 × 10⁻⁷ ferrocene centers/cm² on a mesoporeous ATO electrode. In case of the ATO electrode, the inner walls of the mesopores exhibiting a very large surface are completely modified in the procedure. Beside this large coulometry fast electron transfer kinetics, high stability and low optical density in both oxidation states is observed.The electrodes were checked for their potential use as optically transparent counter electrodes in electrochromic devices.

Electrochemical evaluation of ferrocene carboxylic acids confined on surfactant-clay modified glassy carbon electrodes: oxidation of ascorbic acid and uric acid

We report on the electrochemical behavior of chemically modified glassy carbon (GC) electrodes by using surfactant/clay films, [cetyltrimethylammonium bromide (CTAB)/hydrotalcite-like], containing ferrocenecarboxylic (FC) or ferrocenedicarboxylic (FDC) acid. The results show that the surfactant molecules incorporated into the clay could increase the permeability and the positive surface of the film. The FDC-CTAB-clay-GC modified electrode showed greater stability and redox electroactivity than the FC-CTAB-clay-GC modified electrode. Low concentrations of ascorbic acid (H₂A) and uric acid (UA) in aqueous solution were easily oxidized on the FDC-surfactant-clay-GC modified electrode. The kinetic of the catalytic reactions were investigated by using cyclic voltammetry and rotating disk electrode. The results suggest that the oxidation of H₂A on FDC-CTAB-clay-GC electrode is limited by kinetics while the oxidation of UA is mass transport-limited. The FDC-CTAB-clay-GC modified electrode allows to determine H₂A in presence of UA, and shows good anti-fouling properties towards surface active materials.

Electrochemical properties of ferrocene modified polysiloxane/chitosan nanocomposite and its application to glucose sensor

A ferrocene functionalized polysiloxane was synthesized and its composite with chitosan was prepared. The electrochemical properties in solution and in immobilized states were examined for both the ferrocene functionalized polysiloxane and its composite with chitosan. The composite film exhibits a reversible redox wave at E°′ = +360 mV vs. Ag/AgCl which is 110 mV more negative than that of the ferrocene functionalized polysiloxane film. It can be explained by the introduction of chitosan to enhance the hydrophilicity of the film and increase mass transport rate in aqueous condition. The composite film shows a very facile electron transport behavior with an apparent diffusion coefficient of 3.5 × 10⁻⁶ cm²/s. The scanning electron microscopic analysis of the film, which is in dried state, reveals that the ferrocene polysiloxane forms average 500 nm size spheres and those are evenly distributed in the chitosan matrix to give a homogeneous nanocomposite. The significantly large value of the apparent diffusion coefficient of the ferrocene moieties in the composite film can be explained by the introduction of highly hydrophilic character to the film originated from the high water-uptake capability of chitosan to give solution-like behaviors of the film in solution. The composite is found to be a useful platform to host enzymes to make biosensors and glucose sensing capability is demonstrated.     

Evaluation of 4‐(Dimethylsilyl) Butyl Ferrocene Grafted HTPB as a Burning Rate Modifier in Composite Propellant Formulation using Bicurative System

High burning rate composite propellants are achieved by incorporation of fine particles of oxidizer, transition metal oxides, and liquid ballistic modifiers. However, they pose processing problems, inertness to the composition and migration related issues. To overcome such problems, an attempt was made to incorporate ferrocenyl grafted HTPB as a burning rate modifier by partly replacing HTPB from 10 % to 50 % using TDI/ IPDI bicurative system and to study their processability in terms of viscosity, mechanical, thermal, sensitivity, and ballistic properties. The data on viscosity reveal that there is a marginal enhancement in end of mix viscosity as percentage of ferrocenyl grafted HTPB increases. The mechanical data reveal that tensile strength and elastic modulus increases, whereas percentage elongation decreases compared to base composition. The results on thermal properties infer that, as the percentage of ferrocenyl grafted HTPB increases, onset decomposition temperature decreases. The impact and friction sensitivity data also envisage that sensitivity increases in comparison to base composition. The data on ballistic properties revealed that there is ca. 53 % increase in burning rate, while decrease in “n” value from 0.39 to 0.2 was obtained compared to base composition.
