“…Bedioui's group described electrochemical NO sensors based on nickel porphyrins and phthalocyanine [17,18]. It should be noted that to date most of these NO sensors, pro®ting from the speci®c materials, including those we reported previously [19,20], were all based on materials with a central ion of nickel, such as Ni(salen), nickel porphyrin and nickel phthalocyanine.…”

Electropolymerized ®lm of metal ethylenebis(salicylideneiminate) [(M(salen), M Co, Fe, Cu and Mn] was utilized as material for development of an electrochemical sensor for the determination of NO in solution. The sensors based on polymeric M(salen) were prepared by a means of electropolymerization with cyclic voltammetry (CV) in acetonitrile solution containing M(salen) for optimized cycles. Na®on was used as a second coating to the sensors and differential pulse amperometry (DPA) was used as a subsequent determination technique. The resulted sensors were found to display good activity toward the oxidation of NO with low detection limits and a good linear relationship between the current and NO concentration. The mechanism of the polymeric M(salen) modi®ed sensor was preliminarily studied by using a technique of quantum chemistry and proposed to be a three-dimensional catalytic pattern by conjugation of the electron of the NO molecule and the polymeric M(salen).

“…10 This dehydration probably collaborating in the formation of a stacked structure via Ni-O-Ni oxo bridges. 7 While polyNiTSPP could be grown in the pH 11 buffer, polyNiTSPc had to be prepared in a strongly alkaline solution, 0.1 M NaOH. Even so, for the same number of electropolymerization cycles, the currents of the Ni(II)/Ni(III) process were about twice as high for NiTSPP, demonstrating an easier film formation.…”

Films of nickel tetrasulfophthalocyanine and -p-phenylporphyrin (NiTSPc and NiTSPP, respectively) were obtained by repetitive cyclic voltammetry (RCV) of the 1 mM complex in aqueous solution, while films of the water-insoluble nickel tetraaminophthalocyanine and -p-phenylporphyrin (NiTAPc and NiTAPP, respectively) had to be obtained by RCV of the 1 mM complex in organic solvents. Glassy carbon (GC), ITO, or platinum electrodes were used as substrates. The modified electrodes were characterized by cyclic voltammetry (CV) and UV-visible, infrared, and X-ray photoelectron spectroscopies. The CVs of the sulfo films showed the characteristic peaks of the Ni(II)/Ni(III) process, whereas the CVs of the amino films did not, very small Ni(II)/Ni(III) peaks appearing only after activation by RCV. Upon oxidation to Ni(III) both sulfo films changed from transparent to dark violet. The IR spectra of the polyNiTSPP and the polyNiTSPc films showed bands at 3628 cm -1 and 3500 cm -1 , respectively, which could be due to interstitial water molecules occluded during the polymerization. The Ni 2p XP spectra indicate that the magnetic character of the Ni(II) ions in NiTSPP is dramatically changed by the polymerization, from diamagnetic in the monomer to paramagnetic in the polymeric film, indicating the formation of Ni-O-Ni bridges or of clusters of Ni(OH) 2 . On the contrary, the Ni 2p XP spectra of the unactivated NiTAPP film, in which the Ni(II)/Ni(III) process was absent, showed only diamagnetic Ni(II). Therefore, it is concluded that only paramagnetic Ni(II) ions can be electrooxidized to Ni(III).

“…Fig. S6 shows that an ITO-(Fe 3 O 4 @Au/PVS) 5 electrode exhibits a DA oxidation current which increased linearly with the increase of the scan rate, suggesting that the electrochemical reaction of ITO-(Fe 3 O 4 @Au/PVS) 5 electrode is a surface controlled, indicating a reaction governed by adsorption process, where those particles contribute to a faster charge transfer mechanism [46,47]. Alencar et al observed the same behavior for a 15-bilayer PAH/NiTsPc system [48].…”
