For a series of ferrocenyl thiophenes of type Fe(eta5-C5H4-(4-R-cC4H2S-3-yl))(eta5-C5H4-(C6H3-3,5-(CF3)2) [R = H (3a), OMe (4a)], Fe(eta5-C5H4-(4-R-cC4H2S-3-yl)(eta5-C5H4-CHO) [R = H (3b), OMe (4b)], and Fe(eta5-C5H4-(4-R-cC4H2S-3-yl)(eta5-C5H4-C?N) [R = H (3c), OMe (4c)], the influence of electron-withdrawing substituents at the ferrocenyl moiety and electron-donating groups at the thiophene unit on the electronic behavior of 3a-c and 4a-c is reported. The coupling of the ferrocenyl and the thiophene moieties has been realized using the Negishi C,C cross-coupling reaction protocol. Compounds 3a and 4c were structurally characterized by single-crystal X-ray diffraction studies. In electrochemical measurements the ferrocenyl redox potential depends on the particular substitution at the ferrocenyl and the thiophene unit. Moreover, UV/Vis/NIR studies showed ligand-to-metal charge transfer (LMCT) interactions, which occur after oxidation and are shifted bathochromically as the donor-acceptor energy gap decreases. Using different substituents, possessing electron-withdrawing or donating capabilities, allows adjusting the energy difference between the ferrocenium-acceptor unit and the donating thiophene system.

A cesium fluoride-promoted reductive coupling reaction of acylferrocene tosylhydrazones with arylboronic acids has been developed, producing highly substituted alpha-arylalkylferrocenes in moderate to excellent yields. The reaction employs anionic fluorine to facilitate the cleavage of C?B bond. The developed methodology demonstrates a wide substrate scope and high functional groups tolerance. Moreover, the alpha-arylalkylferrocenes compounds were also obtained on a multi-gram scale.

The reactions of ferrocenyl methanol, ferrocenyl 2-propanol and N-methyl-2-ferrocenylmethylamine with chlorocyclophosphazenes have been examined. The pentachlorocyclotriphosphazene derivative of ferrocenylmethanol undergoes rapid decomposition via a phosphazene-phosphazane rearrangement, however when the alcohol function is beta to the cyclopentadienyl ring modest yields of N3P3Cl5OCHMeCH2C5H 4FeCp may be obtained. By way of contrast N-methyl-2-ferrocenylmethylamine gives a broad range of stable derivatives, N3P3Cl6-n[NMeCH2C5H 4FeCp]n(n=1-3). The substitution process follows a predominantly trans non-geminal pathway. The corresponding reaction with the butylmethacrylate derivative, N3P3Cl5O(CH2) 4OC(O)CMe=CH2 leads to the unexpected geminal product, 2,2?-N3P3Cl4[O(CH2) 4OC(O)CMe=CH2]NMeCH2C5H 4FeCp. Polymers containing the 2-ferrocenylmethylamine function have been obtained by reactions of poly(dichlorophosphazene) with the ferrocenylamine and by radical addition polymerization of the aforementioned mixed ferrocenylamino butylmethacrylphosphazene. The new materials have been characterized by standard methologies including 31P NMR spectroscopy, cyclic voltametry and gel permeation chromatography.

Poly(azine ferrocene-triazole-xanthone amide) (PAFTXA) was successfully synthesized from azine ferrocene bisacetylene (AFcB) and 2,7-(N-2-azidoacetamide) xanthone (NAzX) by using click chemistry protocol. In this paper, innovative AFcB moiety incorporated in this procedure as a monomer. This monomer was prepared in three steps from ferrocene scaffold, and the synthetic processes were discussed in details. Characterization of the synthesized novel intermediate materials, monomer, and the resulting polymer was performed by nuclear magnetic resonance, Fourier transform infrared, thermal gravimetric analysis, differential scanning calorimetry, and ultraviolet-visible spectrophotometer. In addition, the in vitro antibacterial activity of the polymer was appraised against Gram-positive and Gram-negative bacteria by using minimum inhibitory concentration method. Moreover; antitumoral effects of synthesized polymer were evaluated on Hela, MCF-7, and Saos cancer cell lines and compared with normal fibroblast cell line by means of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Promising antiproliferative effects were detected on both epitheloid and mesenchymal cancer cell lines depending on PAFTXA concentration and time. Survey on its characteristic features revealed the proficiencies of our prepared biomaterial such as its high thermal stability as well as valuable antitumoral and antibacterial capabilities that make it an appreciable candidate for further bioapplications.

Electrochemical potential cycling of gold electrodes in commonly used redox active species to produce a nanostructured surface is introduced. A commercially available gold electrode when cycled in three redox active species including hexaammine ruthenium chloride, ferrocene methanol and ferricyanide shows rapid conversion of the surface into a nanostructured form within 50 cycles which usually requires hundreds of cycles in their absence. The active gold nanostructured electrode was characterized by cyclic voltammetry in acidic and alkaline electrolyte indicating the presence of different basal sites depending on the redox species employed. In addition, the active gold nanostructured surface shows higher electrocatalytic activity than the pristine polycrystalline gold electrode for glucose and ascorbic acid oxidation in alkaline media.

A new method was introduced to research the corrosion resistance of enamel coatings which were sintered at different temperatures in this paper.1-4 Scanning electrochemical microscopy (SECM) conjunction with capacitance-potential test and Mott-Schottky analysis technique were used to study the coating failure process and semiconductor conduction behavior of enamel coating in 3.5wt.% NaCl solution. The high strength steel (SAPH440) was selected as the metal substrate. The coatings which were sintered at different temperatures on the high strength steel were analyzed and their corrosion behaviors and microstructures were also measured by potentiodynamic polarization curves, Mott-Schottky analysis technique and scanning electrochemical microscopy.5-10 In this paper, five kinds of enamel coatings were prepared on high strength steel. The SECM results show that the Faraday current of the microprobe tip gradually decreases with the soaking time increasing, which indicates that the coatings become failure slowly with the invasion of water and aggressive ions. At the same time, the tip current was homogeneous during the immersion process, which reflected that the surface of the sample remained stable, no obvious bulges appeared. Capacitance-potential test and Mott-Schottky analysis7,8 show that the external ions and water molecules gradually penetrate into the coating; coating showed characteristics of n-type semiconductor as time increases, the capacitance increases gradually, the space charge layer thickness decreases, slope of Mott-Schottky curve decreased gradually which indicates that the failure of coating in the process of soaking slowly with the charge carrier density increases.
