Scanning Electrochemical Microscopy with Forced Convection Introduced by High-Precision Stirring

In the present report the well-known advantages of hydrodynamic mass transport in electrochemical systems are used in combination with scanning electrochemical microscopy (SECM). The hydrodynamic SECM system integrates a high-precision stirring device into the experimental setup. The well-defined stirring of the SECM electrolyte results in steady state diffusion layer characteristics in the vicinity of large substrate electrodes operated in chronoamperometric measuring mode. For a range of rotation frequencies of a rotating cylinder the thickness and the stability of the diffusion layer was studied by hydrodynamic SECM in the substrate generation/tip collection (SG/TC) as well as in the competition mode using ferrocene methanol as redox mediator. Different UME probe dimensions ranging from Pt diameters of 20 mum down to 0.6 mum were used. The smallest probe with dPt = 0.6 mum was found most suitable for these studies due to the almost convection-independent amperometric response associated with submum electrodes. Additionally, preliminary studies of hydrodynamic SECM imaging of a 2 mm Pt disk electrode surface in the SG/TC mode based on in situ produced hydrogen as a mediator are presented. Comparative images measured in the conventional positive feedback mode in quiescent solution show that hydrodynamic SECM offers attractive complementary information.

Synthesis of citric-acid-based dendrimers decorated with ferrocenyl groups and investigation of their electroactivity

Fc (ferrocene)-functionalized citric acid dendrimers were successfully synthesized via the reaction of citric acid dendrimers with ferrocene methanol using dicyclohexylcarbodiimide. ClOC?PEG?COCl was used as the core, and the related dendrimers were synthesized divergently. Subsequently, each generation was functionalized with ferrocene methanol. The obtained Fc-dendrimers were characterized by 1H NMR and FTIR spectroscopy. We have studied the relocation of electrons around the peripheries of dendrimers and between their redox terminals and electrodes by studies of the electrochemistry of dendrimers awarding metallocenes as functional?s groups, because these compounds can be stabilized together their oxidized and their reduced states. In addition, the voltammograms of each Fc-functionalized generation were studied and the influence of scan rate, solvent, and [Fe] unit and the concentration of the Fc-dendrimers were investigated.

The stability of diazonium ion terminated films on glassy carbon and gold electrodes

Glassy carbon (GC) and Au electrodes were modified with aminophenyl films by electroreduction of the corresponding diazonium salt. Aminophenyl films were diazotised using both aqueous and non-aqueous conditions, to generate film-based phenyldiazonium ions. The stabilities of the diazonium terminated films, to exposure to air and in acidic solution, were investigated by cyclic voltammetry (CV). For films of the same thickness, those grafted to Au substrates are more stable than those grafted to GC.

Synthesis, chemical reactivity and electrochemical behaviour of mono- and difluoro metallocenes

We report the synthesis of mono- and 1,1?-difluoro-substituted metallocenes (ferrocene, ruthenocene) and of asymmetrical 1,1?-disubstituted ferrocenes with one substituent being fluorine. Lithiation of metallocenes and subsequent addition of the fluorinating agent NFSI gave the fluorinated metallocenes after optimization of the experimental conditions. All new compounds were comprehensively characterized and the cyclic voltammograms of fluoro- and 1,1?-difluoroferrocene were recorded and compared to other mono- and dihalogenated ferrocenes. Half-wave potentials of +106 mV and +220 mV vs. FcH0/+ were obtained for monofluorinated species and difluorinated ferrocene, respectively. Both values are remarkably low compared to the other halogenated ferrocenes (Cl, Br, and I). Finally, 1-bromo-1′-fluoro-ferrocene turns out to be an ideal starting material for further fluoro-substituted ferrocene derivatives.

Solution viscosity effects on the heterogeneous electron transfer kinetics of ferrocenemethanol in dimethyl sulfoxide-water mixtures

The electrochemical kinetics for the oxidation of ferrocenemethanol (FcCH2OH) over the whole composition range of dimethyl sulfoxide (DMSO)-water solutions of different viscosities (I¡¤) containing 50.0 mM (CH3)4NClO4 (TMAP) at a Pt microelectrode was studied using scanning electrochemical microscopy (SECM). The measured diffusion coefficient, DFcCH2OH, as well as the standard rate constant of the heterogeneous electron transfer, k0, as a function of solution composition, showed a minimum at about a DMSO molar fraction (xDMSO) of 0.33, corresponding to the mixture with the maximum solution viscosity. The largest k0 value found, 2.06 A¡À 0.31 cm s-1 in pure water (electrolyte) medium, was about 15 times larger than that obtained in the solution of xDMSO = 0.33 (0.14 A¡À 0.02 cm s-1). A good linear correlation between ln k0 and ln I¡¤ was observed within the solution composition range of 0.10 a?? xDMSO a?? 0.60. An excellent linear correlation between ln k0 and ln I?L, the longitudinal relaxation time, was also obtained with a slope equal to 1.0 when xDMSO = 0-0.60. Unusually small rate constants found in the solutions of xDMSO a?? 0.70 were attributed to adsorption effects at the tip and the substrate electrode. The k0 obtained for the present system was generally found to be inversely proportional to the viscosity of the solution and directly proportional to the diffusion coefficient of the electroactive species.

Modular Synthesis of Fischer Biscarbene Complexes of Chromium

Aromatic and (hetero)aromatic chromium aminocarbenes were lithiated on the (hetero)aromatic ring and transmetalated with ZnBr2. The subsequent Pd(PPh3)4- or PdCl2(XantPhos)-catalyzed Negishi reaction with dibromoarenes or chromium alkoxy-/aminocarbenes bearing bromine atoms yielded bisaminocarbene or mixed bisalkoxyaminocarbene complexes of chromium. This methodology allows easy access to the biscarbene complexes containing poly(hetero)aromatic bridges, such as biphenylene, bithienylene, tetrathienylene, 1,1?-ferrocenylene, and others. In total, 18 new biscarbene complexes, including two containing both chromium and tungsten, were synthesized in this fashion. The electrochemical behavior of the biscarbenes obtained exhibits electronic communication between the metals.

An HRP-based amperometric biosensor fabricated by thermal inkjet printing

Direct inkjet printing of a complete and working amperometric biosensor for the detection of hydrogen peroxide, based on horseradish peroxidase (HRP), has been demonstrated. The device has been realized with a commercial printer. A thin layer of PEDOT:PSS, which was in turn covered with HRP, was inkjet printed on top of an ITO-coated glass slide. The active components of the device retained their properties after the thermal inkjet printing. The whole device has been encapsulated by means of a selectively permeable cellulose acetate membrane. The successful electron transfer between the PEDOT:PSS covered electrode and the enzyme has been demonstrated, and the biosensor evidenced very good sensitivity, in line with the best devices realized with other techniques, and a remarkable operational stability. This result paves the way for an extensive application of “biopolytronics”, i.e. the utilization of conductive/semiconductive polymers and biologically active molecules to design bioelectronic devices using a common PC, and exploiting normal commercial printers to print them out.
