Adsorption phenomena in systems containing complexes of cucurbit[7]uril with organic compounds

The aim of this study is to consider the adsorption phenomena at the electrode/solution interface in systems containing complexes of cucurbit[7]uril (CB7) with organic compounds: adamantanol?1, ferrocene and organic dye 3,3??diethylthiocarbocyanine iodide. These guests form exclusively stable inclusive complexes with CB7. Experimental dependences of differential capacitance C as a function of potential were used in calculating the adsorption parameters characterizing the most important properties of adsorption layers formed by compounds under study at the electrode/solution interface. For all the systems studied here, as for those studied earlier, adsorption parameters for negative and positive charges of the electrode surface differ. Obviously this points to deep changes in the properties of adsorption layers depending on the electrode potential.

A portable electrochemical platform integrated with a 3D AuNPS/CNTs sponge for point-of-care testing of neurotransmitters

Point-of-care testing (POCT) of neurotransmitters, such as dopamine (DA) and 5-hydroxytryptamine (5-HT), can be used for early diagnosis of neurological diseases. Among various POCT platforms, electrochemical method-based platforms have attracted increasing interest owning to their high detection sensitivity and specificity as well as fast response time. In this work, we developed a portable electrochemical POCT platform for detection of neurotransmitters, which is based on integration of a three-dimensional (3D) gold nanoparticles/carbon nanotubes (AuNPs/CNTs) sponge synthesized by a simple in-situ growth and eco-friendly ice-templating method modified screen-printed electrode with a miniaturized USB electrochemical analyzer. We demonstrated the good performance of the portable electrochemical platform for detection of two typical neurotransmitters, i.e., DA and 5-HT, with detection sensitivities of 1.02 muA muM?1 cm?2 and 0.55 muA muM?1 cm?2, and detection limits of 0.06 muM and 0.30 muM for DA and 5-HT, respectively. We further verified the feasibility and practicability of the platform by simultaneous detection of DA and 5-HT in spiked saliva. The developed portable electrochemical platform provides a simple and user-friendly way for early diagnosis of neurological diseases in the future, especially at point of care.

Direct dehydroxytrifluoromethylthiolation of alcohols using silver(I) trifluoromethanethiolate and tetra-n-butylammonium iodide

An unprecedented reaction for the direct trifluoromethylthiolation and fluorination of alkyl alcohols using AgSCF3 and nBu4NI has been developed. The trifluoromethylthiolated compounds and alkyl fluorides were selectively formed by changing the ratio of AgSCF3/nBu4NI. This protocol is tolerant of different functional groups and might be applicable to late-stage trifluoromethylthiolation of alcohols.

(Planar-Chiral) Ferrocenylmethanols: From Anionic Homo Phospho-Fries Rearrangements to alpha-Ferrocenyl Carbenium Ions

The reaction of FcCH2OH with chlorophosphates gave ferrocenyl phosphates FcCH2OP(O)(OR)2 [Fc = Fe(eta5-C5H5)(eta4-C5H4)], which readily separate into phosphate anions and ferrocenyl carbo-cations. The latter species undergoes consecutive reactions, for example, electrophilic aromatic substitutions. When nitriles, instead of alcohols, are treated with FcLi or tBuLi and chlorophosphates, chiral-pool based ferrocenylimino phosphoramidates Fc-CR=N-P(O)(OR*)2 are formed, which are promising candidates for anionic homo phospho-Fries rearrangements. Moreover, the sterically demanding chiral chlorophosphate with R* enabled oxidative couplings of the imines to form a diferrocenylazine. Similarly, the reaction of Fc?Li with 9-anthrylnitrile produced a 10-ferrocenyl-substituted product, contrary to a reaction at the C?N functionality. A planar-chiral ortho-P(S)Ph2-functionalized ferrocenylmethanol also gave carbo-cations under acidic conditions. These species can be sulfurized in a unique way giving thio ethers, whereby the in situ formed 1,2-P(S)Ph2,CH2+ ferrocene cation acts as the sulfur and electron source. However, lowering the substrate concentration prevents sulfur migration, resulting in electrophilic substitution reactions with aromatic solvents. Planar-chiral ferrocenylmethyl thio or anisyl derivatives were applied as ligands in Pd-catalyzed Suzuki?Miyaura C,C cross-couplings for the atroposelective synthesis of hindered biaryls with up to 26 % ee at low catalyst loadings (1 mol-% Pd).

Study of the inhibitive effect of mixed self-assembled monolayers on copper with SECM

Mixed self-assembled monolayers (SAMmix) were formed by 2-(Pyridin-2-yliminomethyl)-phenol (HL) and 1-dodecanethiol (DT) molecules on copper surface. The inhibitive ability of SAMmix in sodium chloride solution was characterized in situ by the scanning electrochemical microscope (SECM). The results show that the compactness and the stability of SAM mix, formed by the two organic materials in an appropriate sequence, are improved and the inhibition efficiency (eta%) increases markedly. They also verify that SAMmix are formed due to the existence of collapsed sites and pinhole defects on SAMs of single materials on the surface of copper. The re-arrangement and the competitive adsorption of HL and DT molecules may have impact on the quality of SAMmix. Possible structures of SAM mix are suggested based on the experimental results.

Catecholboryl-functionalized ferrocene based Lewis acid system: A selective probe for fluoride ion through multiple channels

The design and synthesis of two new receptors, C20H 19O3BFe and C20H21O3BFe and their anion sensing properties through multiple channels are reported. Both the receptors, having chelating boronic ester Lewis acidic centre as the sole binding site, selectively bind fluoride ion in micromolar concentration. The binding constant of C20H19O3BFe with the fluoride ion has been found to be quite high [K = 106 M -1], whereas it displays a negligible affinity towards other effective competitors, for example acetate and cyanide (K = 10 M-1) and no sensitivity towards other halide ions. Upon selective recognition of F- in acetonitrile, the redox potential of C20H 19O3BFe shifted by DeltaE = 200 mV and the fluorescence emission was quenched drastically. The considerable changes in their absorption spectra are accompanied by the appearance of a new low energy (LE) peak at 566 nm and by a strong colour change from yellow to deep green which allows the prospective for “naked eye” detection of F- anion.

Unidirectional current flow of reversible redox couples on a MoO3 film-modified microelectrode

In this paper, we have investigated the reactivity of the molybdenum oxide film toward some standard redox systems (e.g., ferrocene (Fc) and its derivatives) and observed a few interesting phenomena. The results demonstrate that the electrochemical behaviour of Fc and its derivatives at the oxide-modified carbon fiber (CF) microelectrode differs from that at a bare CF microelectrode. The conductivity of the molybdenum oxide film is seriously affected by the range and the direction of the potential scan, which influences the electrochemical behaviour of these redox systems at the film electrode. If the cycling potential is more positive than the reduction potential of the molybdenum oxide film, the reduction and oxidation peak currents of Fc and its derivatives could not be observed. The result indicates that the molybdenum oxide film on a microelectrode surface cannot transfer electrons between the surface of the electrode and Fc or its derivatives due to the existence of a high resistance between the interface in these potential ranges. On the other hand, if the lower limit of the scan potential was extended to a potential more negative than the reduction peak potential of the film, the oxidation peak of Fc or its derivatives appeared at about the potential relative to Eo of Fc or its derivatives on the bare electrode, and the peak current is proportional to the concentration of these couples in the electrolyte. To our surprise, the peak height on the modified electrode is much larger than that on the bare CF microelectrode under the same conditions in the range of low concentration of these couples, and the oxidation peak potential of these couples is more negative than that on the bare CF microelectrode. On the basis of the experimental observation, we propose that these redox couples may undergo an interaction with the reduction state of the molybdenum oxide film. The new phenomena that we observed have been explained by using this interaction.

Pt-Decorated MWCNTs-Ionic Liquid Composite-Based Hydrogen Peroxide Sensor to Study Microbial Metabolism Using Scanning Electrochemical Microscopy

Hydrogen peroxide (H2O2) is a highly relevant metabolite in many biological processes, including the oral microbiome. To study this metabolite, we developed a 25 mum diameter, highly sensitive, nonenzymatic H2O2 sensor with a detection limit of 250 nM and a broad linear range of 250 nM to 7 mM. The sensor used the synergistic activity of the catalytically active Pt nanoparticles on a high surface area multiwalled carbon nanotube and conducting ionic liquid matrix to achieve high sensitivity (2.4 ¡À 0.24 mA cm-2 mM-1) for H2O2 oxidation. The unique composite allowed us to miniaturize the sensor and couple it with a Pt electrode (25 mum diameter each) for use as a dual scanning electrochemical microscopy probe. We could detect 65 ¡À 10 muM H2O2 produced by Streptococcus gordonii (Sg) in a simulated biofilm at 50 mum above its surface in the presence of 1 mM glucose and artificial saliva solution (pH 7.2 at 37 C). Because of its high stability and low detection limit, the sensor showed a promising chemical image of H2O2 produced by Sg biofilms. We were also able to detect 30 muM H2O2 at 50 mum above the biofilm in the presence of the H2O2-decomposing salivary lactoperoxidase and thiocyanate, which would not otherwise be possible using an existing H2O2 assay. Thus, this sensor can potentially find applications in the study of other important biological processes in a complex matrix where circumstances demand a low detection limit in a compact space.

Electrochemistry of individual molecules in zeptoliter volumes

Electrochemical experiments were carried out in a nanometer-sized cylindrical thin layer cell (TLC) formed by etching the surface of a disk-type platinum nanoelectrode (5- to 150-nm radius). Using high frequency ac voltage, the surface of such an electrode was etched to remove a very thin (? 1-nm-thick) layer of Pt. The resulting zeptoliter-scale cavity inside the glass sheath was filled with aqueous solution containing redox species, and the etched electrode was immersed in a dry (no external solution) pool of mercury to produce a TLC. Several approaches based on steady-state voltammetry and scanning electrochemical microscopy (SECM) were developed to independently evaluate the electrode radius and the etched volume. The number of redox molecules in the TLC could be varied between one and a few hundred by changing its volume and solution concentration. In this way, the transition between a random and deterministic number of trapped molecules was observed. High quality steady-state voltammograms of ?1 molecules were obtained for different neutral and charged redox species and different concentrations of supporting electrolyte. The analysis of such voltammograms yields information about mass transfer, adsorption, electron transfer kinetics, and double-layer effects on the nanoscale.
