The first sumanene-ferrocene probes for efficient and selective caesium cation (Cs+) recognition are reported. The working mechanism of the sumanene moiety as the sensing unit was based on the site-selective cation-pi interaction in its neutral state. The interactions with Cs+ were characterized by high association constant values together with low limits of detection.

In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool.Reference of 1271-48-3. In my other articles, you can also check out more blogs about 1271-48-3

Chemistry is a science major with cience and engineering. The main research directions are preparation and modification of special coatings, and research on the structure and performance of functional materials. In a patent, 1273-94-5, name is 1,1′-Diacetylferrocene, introducing its new discovery. Quality Control of 1,1′-Diacetylferrocene

Treatment of 1,1?-diacetylferrocene (10) with excess piperidine and a stoichiometric amount of TiCl4 in pentane leads to CC-coupling of the two functional groups at the ferrocene framework. This enamine condensation reaction leads to the formation of the 1,3-connected dienamine-bridged [3]ferrocenophane system 13a. Complex 13a was characterised by X-ray crystal structure analysis. The analogous TiCl4-mediated coupling and condensation reactions of 10 with morpholine, pyrrolidine or methyl-isopropylamine yield the corresponding substituted [3]ferrocenophane systems 13b-d.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states.

In electrochemical systems imperfect thermostating inevitably leads to the presence of bulk convective flows. As recognised by Nernst [Z. Phys. Chem., 1904, 52] damping of these bulk convective flows next to a solid surface, or at the electrode, leads to diffusional mass transport predominating locally. This work questions the exclusivity of diffusional transport and provides hitherto unexplored physical insights into how thermally induced flows in bulk solution can, on both macro- and microelectrodes, influence a voltammetric measurement. Imperfect thermostating results in flows in the bulk solution which are predicted and here expeimentally shown to be of the order of 100 mum s-1. Here we show that even in the absence of natural convective flows induced by the electrochemical reaction itself, this thermally induced bulk convection can significantly affect the voltammetric response. First, evaporative losses from an open electrochemical cell can be sufficient to produce convective flows that can alter the electrochemical response. Second, electrodes with various sizes and geometries have been investigated and experimental results evidence that the sensitivity of an electrode to these flows in bulk solution is to a large extent controlled by the size of the surrounding non-conductive supporting substrate used to insulate parts of the electrode.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis. We will look forword to the important role of 1273-86-5, and how the biochemistry of the body works.Electric Literature of 1273-86-5

The size of the diamond particle is tailored to nanoscale (nanodiamond, ND), and the ND surface is engineered targeting specific (electrochemical and biological) applications. In this work, we investigated the complex surface redox chemistry of immobilized ND layer on conductive boron-doped diamond electrode with a broad experimental parameter space such as particle size (nano versus micron), scan rate, pH (cationic/acidic versus anionic/basic), electrolyte KCl concentration (four orders of magnitude), and redox agents (neutral and ionic). We reported on the significant enhancement of ionic currents while recording reversible oxidation of neutral ferrocene methanol (FcMeOH) by almost one order of magnitude than traditional potassium ferricyanide (K3Fe(CN)6) redox agent. The current enhancement is inversely related to ND particle diameter in the following order: 1 mum << 1000 nm < 100 nm < 10 nm ? 5 nm < 2 nm. We attribute the current enhancement to concurrent electrocatalytic processes, i.e. the electron transfer between redox probes and electroactive surface functional (e.g. hydroxyl, carboxyl, epoxy) moieties and the electron transfer mediated by adsorbed FcMeOH+ (or Fe(CN)6 3+) ions onto ND surface. The first process is pH dependent since it depends upon ND surface functionalities for which the electron transfer is coupled to proton transfer. The adsorption mediated process is observed most apparently at slower scan rates owing to self-exchange between adsorbed FcMeOH+ ions and FcMeOH redox agent molecules in diffusion-limited bulk electrolyte solution. Alternatively, it is hypothesized that the surface functionality and defect sites (sp2-bonded C shell and unsaturated bonds) give rise to surface electronic states with energies within the band gap (midgap states) in undoped ND. These surface states serve as electron donors (and acceptors) depending upon their bonding (and antibonding) character and, therefore, they can support electrocatalytic redox processes in the presence of specific redox-active molecules via feedback mechanism. Apparently, FcMeOH+ tended to have electrostatic affinity for negatively charged ND surface functionalities, corroborated by present experiments. We also attempted to study biocatalytic process using model metalloprotein (cytochrome c; Cyt c) immobilized on ND particles for investigating interfacial electron transfer kinetics and compared with those of functionalized graphene (graphene oxide; GO and reduced GO). The findings are discussed in terms of interplay of sp3-bonded C (ND core) and sp2-bonded C (ND shell and graphene-based systems). Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.

The new types of ferrocenyloxaaliphatic acid ester, FcCHROCHR?COOMe (R = H, Me, Ph; R? = H, Me) (7) have been prepared by the action of alkoxides derived from methyl glycolate or methyl lactate on the corresponding ferrocenylcarbinyl acetates (2) or N,N,N-trimethylferrocylammonium iodides (4). The esters obtained were accompanied by a small quantity of oligomeric esters, FcCHR(OCHR?CO)nOMe (9), and with more or less ferrocyl methyl ethers (8). As opposed to the alkaline hydrolysis of the analogous methyl benzoxyacetate (6) into benzoxyacetic acid (5) the acidification of sodium alkanoates 10 obtained by saponification of esters 7 gave unexpectedly the corresponding ferrocenylcarbinols 1. In a similar way the esters 7 were converted into mixtures of the mentioned carbinols and diferrocyl ethers 11 under action of aqueous hydrochloric acid. The mechanisms of the reactions 10 ? 1 and 7 ? 1, 11 are discussed.

One problem encountered in the development of rechargeable lithium batteries is protection of individual cells from overcharging. In this work the addition of metallocene derivatives to cell electrolytes to provide overcharge protection was investigated. Eleven ferrocene derivatives were studied in terms of their redox potentials and mass transport properties in electrochemical cells and ‘AA’ size Li/LixMnO2 rechargeable cells employing 1M LiAsF6 in 50/50 volume percent propylene carbonate/ethylene carbonate (PC/EC) as the electrolyte. The chemical and electrochemical properties of these metallocene derivatives were also studied in terms of the chemical stability of the derivatives toward cell components and electrochemical reversibility in long-term cycling studies. It was found that adsorption of one derivative, dimethylaminomethylferrocene, on the LixMnO2 electrode (DeltaGads = -3.8 Kcal mol-1 based on the Langmuir adsorption isotherm), blocked the intercalation of Li+ ions into the LixMnO2 electrode.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. In my other articles, you can also check out more blogs about 1273-86-5

We investigate the Faradaic currents of ferrocene species at an electrode-membrane-electrode system. The membrane electrodes system is fabricated by physical sputtering of conductive metal on both sides of a nanoporous alumina membrane. The metal coatings function as working electrodes by connection to a bipotentiostat and reference/counter electrodes in the sample solution. Collection and shielding efficiency studies are carried out at this membrane electrodes system to measure mobility values of charged ferrocene species within nanochannels of alumina membrane. Results indicated high selective electrode response of up to 16 times for positively charged (dimethylaminomethyl)ferrocene (FcN), and neutral ferrocenemethanol (FcMeOH), compared to the negatively charged ferrocenecarboxylic acid (FcCOOH) when the receiver electrode was maintained at negative potentials of 0.5-1.0 V relative to the feed electrode. This is a report on the use of an electrode-membrane-electrode system to achieve selective response towards differently charged redox species, under the condition of high electrolyte concentration (0.1 M, pH 7.0 phosphate buffer).
