“…The detection limit of 3.4 × 10 −9 mol L −1 is comparable to that seen for other adsorptive stripping methods [39,40]. The Ni(II)-salen polymeric film could be applied as a sensor in the determination of dissolved oxygen, dipyrone and as an electrochemical energy storage system [51][52][53]. As the solution of Ni(II)-salen in DMF is water-soluble, we are trying to study the effect of the complex solution on DNA cleavage.…”

The complex Ni(II)-salen has been studied using cyclic and square-wave cathodic stripping voltammetry at the static mercury drop electrode in an aqueous media of phosphate and Hepes buffers (at pH 7.0). The resulting voltammograms consist of a totally irreversible one-electron transfer attributable to the coupling of Ni(II) salen/Ni(I) salen via an EC mechanism. The mean value for the transfer coefficient in both supporting electrolytes was calculated as 0.35 ± 0.05. The amount of reactant adsorbed after 60 s of accumulation at −700 mV was calculated to be 2.8 × 10 −8 mol⋅cm −2 . The detection limit for nickel determination was found to be 3.4 × 10 −9 mol L −1 .

“…[1][2][3][4] The salen type transition metal conducting polymer could be polymerized to the anode and form electrochemical active films in solvents with weak donor numbers (acetonitrile and solvents with lower DN values) which prompted their use in heterogeneous electrocatalysis. [5][6][7] In nonaqueous electrolyte system, the electroactive films could not only change reversibly at a higher voltage between neutral and oxidation state, 8 but also can change reversibly at a lower voltage between neutral and reduction state, 9,10 in order to storage and release charge continuously.…”

Poly[Ni(salen)] films were electropolymerized on multiwalled carbon nanotubes (MWCNTs) in tetrabutylammonium perchlorate/acetonitrile by cyclic voltammetry method. And the employed scan rates were 5, 10, 20 and 40 mV s . The excellent electrochemical performance of poly[Ni(salen)] electropolymerized at 20 mV s −1 is ascribed to the better conductivity and superior diffusion ability according to the kinetics.

“…where M is the molecular mass of the monomer (339.02 g mol −1 ), Q is the charge, calculated by the integration of the anodic peak obtained from the cyclic voltammogram in KCl (v = 25 mV s −1 ), n is the number of electrons transferred (assumed to be 1), F the Faraday constant (96485 C mol −1 ), A the electrode area (in cm 2 ) and the film density (∼1 g cm −3 ) [4]. The Ni-Salpn film thicknesses were: 41 nm on the GC electrode, 18 nm, 12 nm and 2.8 nm for the Au, ITO and Pt electrodes, respectively.…”

“…Metal-Schiff complexes with tetradentate N 2 O 2 ligands are being widely studied as modifiers of electrodes by oxidative electrodeposition on a variety of conducting surfaces [1][2][3][4]. The electrodeposition mechanism has been extensively discussed in the literature by Goldsby et al [5,6] and Audebert et al [7][8][9], in which radical-radical coupling was proposed.…”

Influence of electrode material EQCM UV-vis and Raman spectroscopy a b s t r a c t Modified electrodes based on films of Schiff base complexes are excellent candidates for sensing applications. The influence of the electrode material, glassy carbon, platinum, gold or indium tin oxide, on the electrodeposition of nickel-N,N'-bis(salicylidene)-1,3-propanediamine (Ni-Salpn) films in 1,2-dichloroethane (DCE) was investigated, and their electrochemical behaviour was evaluated by cyclic voltammetry and electrochemical impedance spectroscopy. The effect of the electrodeposition potential and electrodeposition time on the electrochemical behaviour of Ni-Salpn was examined using glassy carbon as substrate. The film growth process was investigated using the electrochemical quartz crystal microbalance and UV-vis absorption spectroscopy and structural differences between the Ni-Salpn complex and the Ni-Salpn film were examined by micro-Raman spectroscopy. The results demonstrate that the electrodeposition mechanism is independent of the electrode material, but that the nature of the substrate material influences the rate of film growth, the electrochemical behaviour and the stability of the film-modified electrodes in aqueous solution. Counteranion insertion during oxidation can break the bonds between the complexes in the stacked Ni-Salpn film structure and cause both mass loss and blockage of the redox metal centre activity, but these effects are small in thin films.
