Localized electrochemical characterization of organic coatings: A brief review

Local electrochemical techniques such as scanning electrochemical microscopy, scanning vibrating electrode technique, local electrochemical impedance spectroscopy, scanning Kelvin probe technique, and scanning ion-selective electrode technique have gained significant attention in organic coating research. These techniques have enhanced our understanding of the fundamental processes of corrosion at defects and underneath coatings. Each of these techniques employ unique measurement strategy to provide important local information about coatings, their protective properties, defects, and failure mechanisms. In this brief review, the basic principles of these techniques and the nature of information that has been extracted from these techniques to study organic coatings are discussed.

Reactions of ferrocenyl amines and alcohols with hexachlorocyclotriphosphazene

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.

Electrochemical detection of amyloid-beta oligomer with the signal amplification of alkaline phosphatase plus electrochemical-chemical-chemical redox cycling

Soluble amyloid-beta oligomer (AbetaO) is believed to be a reliable molecular biomarker for the diagnosis of Alzheimer’s disease (AD) because of its high toxicity for neuronal synapse and higher concentration level in cerebrospinal fluid sample from AD patient than from control individual. At present, it is critical to develop a simple method for AbetaO detection with low cost as well as high sensitivity and selectivity. In this work, we reported an antibody-free electrochemical method for the detection of AbetaO based on the specific interaction between AbetaO and PrP(95-110) peptide, a segment of cellular prion protein. Specifically, cysteine-containing PrP(95-110) peptide was first immobilized on a gold electrode for the capture of AbetaO. Then, alkaline phosphatase-conjugated PrP(95-110) was used for the recognition of the captured AbetaO and the generation of electroactive species. Furthermore, an “outer-sphere to inner-sphere” electrochemical-chemical-chemical (ECC) redox cycling using ferrocene methanol as the redox mediator was employed to enhance the detection sensitivity. As a result, a detection limit of 3 pM for equivalent monomer was achieved. The amenability of this method to AbetaO analysis in a biological matrix was demonstrated by assays of AbetaO in serum samples.

Synthesis and characterization of new ferrocene-containing ionic liquids

A series of several new families of ferrocene-containing imidazolium salts were synthesized by etherification of ferrocene methanol, acylation of ferrocene, and amide coupling of ferrocene carboxylic acid. The etherification was achieved by an acid-catalyzed procedure and very good yields of between 86-93-% were obtained. Next to the nature of the linkage itself, the lengths of the alkyl chains linking the ferrocenyl moiety and the imidazolium group and the nature of the counterions were also varied. Interestingly, a gamma-effect can be observed for the ether compounds but this effect was only visible in 13C NMR spectroscopy. These new redox-active ionic liquids were fully characterized by FTIR, 1H, 19F, and 13C NMR spectroscopy, and by MS, HRMS and elemental analysis. A novel series of ferrocenated ionic liquids with different spacer species between the ferrocenyl moiety and the imidazolium group have been developed. The spacer units have been established by amide coupling, etherification and acylation. The latter reaction is strongly influenced by the chain length of the acid chloride and a gamma-effect is observable for the ether compounds. Copyright

Reduced graphene oxides: Influence of the reduction method on the electrocatalytic effect towards nucleic acid oxidation

For the first time a critical analysis of the influence that four different graphene oxide reduction methods have on the electrochemical properties of the resulting reduced graphene oxides (RGOs) is reported. Starting from the same graphene oxide, chemical (CRGO), hydrothermal (hTRGO), electrochemical (ERGO), and thermal (TRGO) reduced graphene oxide were produced. The materials were fully characterized and the topography and electroactivity of the resulting glassy carbon modified electrodes were also evaluated. An oligonucleotide molecule was used as a model of DNA electrochemical biosensing. The results allow for the conclusion that TRGO produced the RGOs with the best electrochemical performance for oligonucleotide electroanalysis. A clear shift in the guanine oxidation peak potential to lower values (~0.100 V) and an almost two-fold increase in the current intensity were observed compared with the other RGOs. The electrocatalytic effect has a multifactorial explanation because the TRGO was the material that presented a higher polydispersity and lower sheet size, thus exposing a larger quantity of defects to the electrode surface, which produces larger physical and electrochemical areas.

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.

Methylenespiro[2.3]hexanes via Nickel-Catalyzed Cyclopropanations with [1.1.1]Propellane

[1.1.1]Propellane is a highly strained tricyclic hydrocarbon whose reactivity is dominated by addition reactions across the central inverted bond to provide bicyclo[1.1.1]pentane derivatives. These reactions proceed under both radical and two-electron pathways, hence, providing access to a diverse array of products. Conversely, transition metal-catalyzed reactions of [1.1.1]propellane are underdeveloped and lack synthetic utility, with reported examples generally yielding mixtures of ring-opened structural isomers, dimers, and trimers, often with poor selectivity. Herein, we report that nickel(0) catalysis enables the use of [1.1.1]propellane as a carbene precursor in cyclopropanations of a range of functionalized alkenes to give methylenespiro[2.3]hexane products. Computational studies provide support for initial formation of a Ni(0)-[1.1.1]propellane complex followed by concerted double C-C bond activation to give the key 3-methylenecyclobutylidene-nickel intermediate.

Modification of Gold’s Work Function upon Adsorption of Mercaptobiphenylcarbonitrile: Experimental Evidence for a Theoretical Prediction

Tuning the energy of the frontier orbitals of an adsorbed molecule to match the Fermi level of the electrode is a fundamental requirement for efficient charge injection in molecular electronic devices. In this paper, we present electrochemical, impedimetric, spectroscopic, and scanning electrochemical microscopy (SECM) data that were used to study the effects of the adsorption of 4?-mercaptobiphenylcarbonitrile (HS2PCN) on the work function of gold. The adsorption process was studied and indicated the formation of a loosely packed self-assembled monolayer (SAM, DeltaGads = -43.3 kJ mol-1) following the immersion of the gold substrate in an ethanolic solution of HS2PCN. An increase in the immersion time resulted in the accumulation of negative charge density on the gold surface ascribed to the bonding dipoles resulting from the charge rearrangement at the metal-SAM interface that generates interfacial dipoles as a result of a charge-transfer process. As a consequence, a modification of about 1.2 eV is estimated in the work function of the gold surface modified with HS2PCN. Electron-transfer rate constants (k0), as measured via SECM, showed a strong dependence on the net charge of the redox probes and increased on going from negatively (ca. 1.14 ¡Á 10-3 cm s-1) to positively charged species (>1.0 cm s-1). Such behavior is ascribed to the polarity of the interface of the HS2PCN SAM on gold, which is negatively charged because of the electron-withdrawing property of the nitrile fragment.
