Synthesis, Properties, and Electron Transfer Studies of Ferrocenyl Thiophenes

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.

Triggered Metal Ion Release and Oxidation: Ferrocene as a Mechanophore in Polymers

The introduction of mechanophores into polymers makes it possible to transduce mechanical forces into chemical reactions that can be used to impart functions such as self-healing, catalytic activity, and mechanochromic response. Here, an example of mechanically induced metal ion release from a polymer is reported. Ferrocene (Fc) was incorporated as an iron ion releasing mechanophore into poly(methyl acrylate)s (PMAs) and polyurethanes (PUs). Sonication triggered the preferential cleavage of the polymers at the Fc units over other bonds, as shown by a kinetic study of the molar mass distribution of the cleaved Fc-containing and Fc-free reference polymers. The released and oxidized iron ions can be detected with KSCN to generate the red-colored [Fe(SCN)n(H2O)6?n)](3?n)+ complex or reacted with K4[Fe(CN)6] to afford Prussian blue.

Tailoring molecular permeability of nanochannel-micelle membranes for electrochemical analysis of antioxidants in fruit juices without sample treatment

Antioxidants are widely found or used in food, pharmaceutical, and cosmetics industries; thus, rapid and sensitive detection of antioxidants is of great interest. The present work reports a simple and fast electrochemical method for direct analysis of antioxidants in fruit juices by modulating the permeability of mesochannels on the electrode surface. This goal was achieved by growing vertical silica mesochannel array (SMA) with a channel diameter of 2-3 nm on the indium tin oxide (ITO) electrode surface using the cylindrical micelles (CMs) as the template. As-prepared electrodes, designed as CM@SMA/ITO, are only permeable to lipophilic antioxidants, e.g., retinol, with the hydrophobic hydrocarbon cores of CMs. After excluding CMs from silica mesochannels, the ITO electrode modified with bare SMA, namely SMA/ITO, possesses a high density of silanol groups on the channel wall and thus is only permeable to hydrophilic antioxidants, such as ascorbic acid (AA). Two types of sensors allowed the selective analyses of retinol and AA in buffer solutions and demonstrated a wide linear range for retinol (1-60 muM) and AA (10-2000 muM), respectively, and a low detection limit (0.65 muM for retinol and 0.52 muM for AA). Moreover, the SMA/ITO electrode can selectively determine the concentration of AA in orange juice. The CM@SMA/ITO electrode can measure the sum activity of lipophilic antioxidants, such as retinol, alpha-tocopherol, and others possibly coexisting, in carrot juice. In addition, the ultrasmall mesochannels and CMs could effectively exclude the access of large substances, rendering an excellent antifouling and anti-interference ability for direct analysis of antioxidants in fruit juices without sample pretreatment.

Recent developments, characteristics and potential applications of screen-printed electrodes in pharmaceutical and biological analysis

Screen-printed electrodes (SPEs) have gone through significant improvements over the past few decades with respect to both their format and their printing materials. Thus, SPEs have been successfully applied for the in situ detection of a plethora of analytes in a wide range of sample matrixes due to their advantageous material properties, such as disposability, simplicity, and rapid responses. In particular, the development of electrochemical sensors based on SPEs for pharmaceutical analysis has received massive consideration since they enable the rapid screening of the pharmaceutical compounds in complex matrixes, requiring small volumes of samples and no pre-treatment steps. This review summarizes the design and the working principles of electrochemical sensors based on SPEs applied to the quantification of pharmaceutical and biological compounds.

Extended Investigation of Electrochemical CO2 Reduction in Ethanolamine Solutions by SECM

The electrochemical reduction of carbon dioxide is very much in the focus of interest today. Intensive research is carried out in leading laboratories trying to work out methods for making useful materials from this unwanted greenhouse gas using solar or wind power generated excess electric energy. In this work, electrochemical reduction experiments are carried out in homemade cells supplied with different metal electrodes. Electrolytes containing carbon dioxide absorbing components like monoethanolamine (MEA) or KHCO3, KOH, and K2CO3 solutions are used. Metal-containing species were noticed in the used electrolytes after being in contact with the metal working electrodes. Therefore parallel to the electrochemical measurements, the metal components in the electrolyte were checked with atomic absorption methods for getting better insight into the nature of the electrode passivation. This paper attempts to compare the behavior of different electrode materials (copper, nickel) in CO2 capturing media, and investigate of the products of the electrolysis using Scanning Electrochemical Microscopy (SECM), Atomic Absorption Spectroscopy (AAS) and gas chromatography.

Synthesis of controlled pi-extended conjugate nanostructures of 1,1?-ferrocene

Synthesis of the (E,E)-1,1?-ferrocene nanostructures having controlled pi-extended conjugation was satisfactory carried out starting of 1?-[2-(1,3-dioxolan)]-1-formylferrocene (1). The molecular unit (E)-1?-[2-(1,3-dioxolan)]-1-[beta-(p-iodophenyl)ethenyl]ferrocene (2), was obtained in excellent yield by treatment of 1 with p-iodobenzyl triphenylphosphonium ylid followed by Z?E isomerization, catalyzed by iodine, in quantitative yield. Compound (E)-2 was transformed in (E)-1?-{2-(1,3-dioxolan)-1-[beta-[4-(3-hydroxy-3-methyl-but-1-ynyl)-phenyl]-ethenyl}ferrocene, (E)-4, by palladium catalyzed cross-coupling with 2-methyl-but-3-yn-2-ol. (E)-4 gives (E)-1-[beta-(4-ethynylphenyl)-ethenyl]-1?-[2-(1,3-dioxolan)]ferrocene (E)-5 by powder sodium hydroxide treatment. The molecular unit (E,E)-1-{beta-[4-(beta-(1?-formylferrocenyl)-ethenyl)-phenylethynyl]-phenyl]-ethenyl}-1?-formylferrocene, (E,E)-6, was synthesized by palladium catalyzed cross-coupling between the p-iodophenyl derivative (E)-2 and their ethynyl derivative (E)-5, in good yield. The (E,E)-1,1?-(p-iodophenyl)ethenyl ferrocene, (E,E)-7, was synthesized by reaction between 1,1?-diformylferrocene and the p-iodobenzyltriphenylphosphonium ylid, as a mixture of isomers which were purely isolated. Moreover, isomerization of the Z,Z and E,Z mixture to the E,E isomer, was induced by sunlight exposure, catalyzed by iodine, in quantitative yield. The (E,E)-1,1?-[beta-(4-ethynylphenyl)-ethenyl]ferrocene, (E,E)-10, was synthesized in good yield, by palladium catalyzed cross-coupling of compound (E,E)-7 with 2-methyl-but-3-yn-2-ol, followed by powder sodium hydroxide treatment.
