“…The electrochemical behaviour of chloramphenicol associated to the reduction of nitrophenyl group to the respective hydroxylamine is well reported in the literature , but tend to be slow. However, electrodes modified with nickel hydroxide are known to generate the Ni 3+ O(OH) species responsible for the catalytic oxidation of hydroxyl and amino groups present in chloramphenicol with relative fast kinetics , , . The CVs of Ni‐100, Ni‐75, Ni‐50, Ni‐25 and Co‐100 in the absence and presence of increasing concentrations of Chloramphenicol (0.1 mmol/L to 0.6 mmol/L) are shown in Figure .…”

Mixed Ni−Co tetraruthenated porphyrin films were successfully electropolymerized on glassy carbon electrodes in alkaline solutions (pH=13) of NiTRP and CoTRP, giving excellent electrocatalytic responses for determination of the antibiotic drug chloramphenicol. Electrodes with four different compositions were obtained by varying the ratio of NiTRP and CoTRP in the deposition solution. For the characterization of these materials, SEM, ICP‐MS, EIS and CV were explored. The porphyrin modified glassy carbon electrodes presented two oxidation peaks for chloramphenicol (except for Ni‐25). The potential shifted to lower values as the percentage of CoTRP increased decreasing its oxidation potential in more than 200 mV for Ni‐50 as compared to Ni‐100. Interestingly, the materials with cobalt content larger than 50 % did not show the typical catalytic response of the NiIIIOOH species, but rather showed an increase in current at potentials larger than 0.4 V, demonstrating the key role played by nickel in this type of materials. The composition of polymeric mixed porphyrin materials influenced the oxidation current response of both redox waves, resulting in different sensitivities on the calibration curves.

“…The same porphyrin The use of nanoparticles of conducting polymer of NiTPPS (PNi-TPPS-NPs) as electrocatalyst for hydrazine oxidation was recently reported by Zakavi and co-workers. 220 The deposition of the sensing nanomaterial onto the GCE was accomplished in two steps, first by electrodepositing Ni NPs at −1.3 V potential onto the electrode surface and then by dipping the modified substrate into an alkaline solution containing the porphyrin monomer, to form the PNi-TPPS-NPs by cyclic voltammetry. The electrooxidation of hydrazine occurred at the electrode surface through a catalytic mechanism involving the Ni(II)/Ni(III) redox center.…”

Porphyrins and related macrocycles have been intensively exploited as sensing materials in chemical sensors, since in these devices they mimic most of their biological functions, such as reversible binding, catalytic activation, and optical changes. Such a magnificent bouquet of properties allows applying porphyrin derivatives to different transducers, ranging from nanogravimetric to optical devices, also enabling the realization of multifunctional chemical sensors, in which multiple transduction mechanisms are applied to the same sensing layer. Potential applications are further expanded through sensor arrays, where cross-selective sensing layers can be applied for the analysis of complex chemical matrices. The possibility of finely tuning the macrocycle properties by synthetic modification of the different components of the porphyrin ring, such as peripheral substituents, molecular skeleton, coordinated metal, allows creating a vast library of porphyrinoid-based sensing layers. From among these, one can select optimal arrays for a particular application. This feature is particularly suitable for sensor array applications, where cross-selective receptors are required. This Review briefly describes chemical sensor principles. The main part of the Review is divided into two sections, describing the porphyrin-based devices devoted to the detection of gaseous or liquid samples, according to the corresponding transduction mechanism. Although most devices are based on porphyrin derivatives, seminal examples of the application of corroles or other porphyrin analogues are evidenced in dedicated sections.

“…Porphyrin-based thin films are currently used in various fields and for many applications because of their interesting physico-chemical properties [1]. Indeed, these materials operate in different devices for nonlinear optical and optical limiting devices [2], photoluminescent biosensors [3], electrochemical or spectrometric sensors [4][5][6][7][8][9][10][11][12], molecular electronic junctions [13][14] and electrocatalytic systems [15][16]. Previous studies of our group have shown that the electrochemical oxidation at low potential of the fully unsubstituted porphyrin, i.e.…”
