Chapter 3: Key Roles of Cavity Portals in Host-Guest Binding Interactions by Cucurbituril Hosts

This chapter summarizes research work showing that electrostatic interactions may have considerable effects on the stability of complexes formed by the cucurbit[n]uril hosts. Focusing primarily on work carried out by the author’s research group with the cucurbit[7]uril (CB[7]) molecular receptor, this review highlights the role played by electrostatic interactions involving the host cavity portals, in which considerable negative charge density accumulates due to the carbonyl oxygens lacing the portal rims. Electrostatics are responsible for diminished binding affinities between CB[7] and a number of anionic guests containing one or more carboxylate groups. These electrostatic interactions can be used effectively to control the average location of CB[7] along axle-type guests having terminal -COOH groups as a function of their state of protonation, leading to switchable pseudorotaxane systems. They can also be utilized to advantage to develop favorable lateral interactions between CB[7] and other molecular receptors, which results in systems showing cooperative self-assembly.

Differentiating between ageing times of typical Chinese liquors by steady-state microelectrode voltammetry

A typical Chinese liquor was characterised using a triple-electrode system with clean and simple design. In this approach, liquors were analysed with no other pre-treatment than mixing the liquor with a potassium chloride solution to ensure sufficient conductivity. Two broad reduction peaks at [?0.3 V, ?0.5 V] and [?0.7 V, ?0.8 V] were present in the cyclic voltammetry, demonstrating the feasibility of the gold electrode for liquor characterisation. Both the competing reactions in the liquor samples contributed to the reduction current. Thus, the steady-state microelectrode voltammetry affords an opportunity to estimate the total concentration of the redox-active species in the mixed compounds according to the relationship between the total concentration and the value of limiting diffusion current. Further, the discrimination of liquors at different ageing times was realised by the conjunction of the electrochemical results and principal component analysis.

Inclusion complexes of ferrocenes and beta-cyclodextrins. Critical appraisal of the electrochemical evaluation of formation constants

We report the results of a systematic electrochemical study of the host-guest supramolecular adducts between ferrocene (Fc), ferrocenium cation (Fc+), and other mono- and disubstituted ferrocene derivatives with different beta-cyclodextrins (CD) in mixed organic-aqueous media. The influence on the formation constants (Kf) of the organic cosolvent, the different substituents on Fc, and the type of CDs are evaluated. NMR and conductometry responses of ferrocenium cation solutions in the presence of CD confirm the weak propensity of Fc+ to enter into the cyclodextrin cavity. The Kf value generally decreases as the steric bulk and the rigidity of Fc substituents increases, consistent with an inclusion model in which the Fc fits into the CD cavity in an axial mode while the substituent protrudes out. Interestingly, the addition of sulfated beta-CD shifts the redox Fc/Fc+ couple toward cathodic values, indicating that the oxidized, cationic form Fc+ is more strongly bound to the sulfated cyclodextrin than neutral Fc, probably by means of electrostatic interaction with the external -SO3- functionalities.

Ultrasensitive electrochemical sensing platform based on graphene wrapping SnO2 nanocorals and autonomous cascade DNA duplication strategy

In this work, a sensitive, universal and reusable electrochemical biosensor based on stannic oxide nanocorals-graphene hybrids (SnO2 NCs-Gr) is developed for target DNA detection by using two kinds of DNA enzymes for signal amplification through an autonomous cascade DNA duplication strategy. A hairpin probe is designed composing of a projecting part at the 3?-end as identification sequence for target, a recognition site for nicking endonuclease, and an 18-carbon shim to stop polymerization process. The designed DNA duplication?incision?replacement process is handled by KF polymerase and endonuclease, then combining with gold nanoparticles as signal carrier for further signal amplification. In the detection system, the electrochemical?chemical?chemical procedure, which uses ferrocene methanol, tris(2-carboxyethyl)phosphine and L-ascorbic acid 2-phosphate as oxidoreduction neurogen, deoxidizer and zymolyte, separately, is applied to amplify detection signal. Benefiting from the multiple signal amplification mechanism, the proposed sensor reveals a good linear connection between the peak current and logarithm of analyte concentration in range of 0.0001?1 ¡Á 10?11?mol?L?1 with a detection limit of 1.25 ¡Á 10?17?mol?L?1 (S/N=3). This assay also opens one promising strategy for ultrasensitive determination of other biological molecules for bioanalysis and biomedicine diagnostics.

Surface Redox Chemistry of Immobilized Nanodiamond: Effects of Particle Size and Electrochemical Environment

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?<Iron Catalysis in Organic Synthesis | Chemical Reviews,

An unprecedented deoxygenation protocol of benzylic alcohols using bis(1-benzotriazolyl)methanethione

A facile and regioselective two-step protocol for the deoxygenation of benzylic alcohols using bis(benzotriazole)methanethione has been devised. Benzotriazole derivatives, namely, benzyloxythioacylbenzotriazoles (ROCSBt), on reaction with silanes or Bu3SnH under microwave irradiation or conventional heating undergo a free radical beta-scission of C-O bond instead of N-N bond (benzotriazole ring cleavage) to afford a deoxy product. The methodology has various applications because it selectively deoxygenates benzylic alcohols with the aid of a relatively nontoxic (TMS)3SiH reagent as an acceptable alternate to Bu3SnH.

Voltammetric demonstration of thermally induced natural convection in aqueous solution

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.

Exploring the enhancement of electron tunneling induced by intermolecular interactions on surface of self-assembled monolayer

The topic of intermolecular interactions enhancing electron tunneling between protein residues on biofilm surface has been investigated by some theoretical studies. However, few of experimental studies could confirm this viewpoint. In this work, the Mercaptopropionic acid self-assembled monolayer (MPA SAM) with terminal carboxyl groups was constructed, as a simplified model for functionalized biomimic membrane. The electron tunneling rate constant of ferrocenylmethanol redox process on SAM was obtained from experimental results of scanning electrochemical microscopy. It is found that the electron tunneling across MPA SAM is faster than that of contrastive Methyl mercaptopropionate SAM. This result is attributed to the intermolecular interactions between the redox and MPA molecules. The conditions of lower pH and weaker ion pair effect all benefit the formation of the intermolecular interactions, resulting the enhancement of electron tunneling more obvious. Based on this, this kind of intermolecular interaction is inferred to be intermolecular hydrogen bond. Our work may have contributions to exploring electron tunneling between protein residues on biofilm surface.
