“…Contrarily, the insertion of pauses resulted in continuous deactivation. Here, when the substrate was 2-phenoxyethanol dissolved in mesityl oxide showed very similar behaviour to phenol published in [16] when ten voltammograms were repeated immediately after each other as the second scan had the minimum and the further values converged to a steady state (Fig. 1d).…”

“…In a previous study, phenol was investigated in mesityl oxide solvent and identical oxidation behaviour could be observed on platinum electrode [16]. As mesityl oxide has an unsaturated carbon-carbon double bond, this solvent participates in the polymerization processes initiated by the electrochemically generated radicals which were demonstrated in that work.…”

“…An interesting solvent is mesityl oxide as it was shown in one of our recent works [16]. Anodic peaks at higher potentials than 2 V are due to electrooxidation of substrate, but in the reverse scan, a small reduction peak appeared at around 0.5 V. The latter could be only observed in mesityl oxide and with platinum electrode attributed to the oxo groups of adsorbed organic layer.…”

“…1e). Earlier [16], when phenol was the substrate the electrode fouled almost completely in the third scan suggesting the deposition of a compact layer. By the electropolymerization of phenol, we also concluded that the solvent mesityl oxide also takes part in the coating formation contributing to the low porosity.…”

Electrooxidation of selected phenylethers was investigated (2-phenoxyethanol, anisole, o-nitrophenyl octyl ether, diphenylether, fenoxycarb) on platinum and glassy carbon electrodes. The chosen solvents were acetonitrile, dimethyl sulphoxide, 1-propanol and mesityl oxide. In acetonitrile, at around 2 V characteristic voltammetric peaks appeared for all compounds. In dimethyl sulphoxide and 1-propanol, no relevant peak appeared due to the high overlapping with solvent electrooxidation. During anodic oxidation of o-nitrophenyl octyl ether and fenoxycarb, a bimolecular reaction takes place predominantly. In mesityl oxide due to its unsaturated bond, identical behaviour was observed for majority of compounds and the differences between the two electrodes are also highlighted in the surface studies. The images made with the aid of an optical microscope showed the formation of islands of products for each substrate after deposition from mesityl oxide.

“…In addition, phenol can lose electrons to form free radicals and undergo irreversible polymerization under certain conditions. 32,33 Marx et al used an electrochemical method to prepare a copolymer coating of tyrosine and Arg-Gly-Asp-Tyr (RGDY) in one step and have achieved the ideal effect. 34 Herein, a cell recognition polypeptide RGDY and an oligopoly(ethylene glycol) derivative were used for copolymerization by cyclic voltammetry (CV) with the mechanism of phenol electropolymerization (Scheme 1 and Scheme 2).…”

Arg-Gly-Asp (RGD), a classical polypeptide, has been widely used in cell specific recognition. RGDY (Arg-Gly-Asp-Tyr) consists of the RGD sequence and tyrosine. Herein, a functional coating with cell-specific adhesion (with human umbilical vein endothelial cells as the model) and antiprotein adhesion (with bovine serum albumin as the model) properties was green synthesized by electrochemical copolymerization of RGDY and 4-(2-(2-ethoxyethoxy) ethoxy) phenol. Fourier transform infrared spectroscopy and scanning electron microscopy were used to characterize the functional groups and morphology of the copolymer, respectively. Cyclic voltammetry and electrochemical impedance spectroscopy were used to study the electrochemical performance of the modified electrode. A quartz crystal microbalance was used to reflect the modification and antiprotein adhesion process of the copolymer and the following process of cell-specific adhesion. The cell adsorption and antiprotein adhesion properties of the modified electrode are significantly improved. Herein, a green method was used to prepare a stable coating with cell-specific adhesion and antiprotein adhesion by electrochemical copolymerization of typical cell-specific recognition peptides and oligopoly(ethylene glycol) derivatives. It has a potential application value in the modification of biomaterials, the preparation of cell-specific sensors, and the development of special biological carriers.

Catechol is a substance that is commonly found in wastewaters from a variety of sectors including paper, paint, petroleum, dyes, antioxidants, pesticides, iron and steel, solvents, nylon, detergent, textile, plastic, rubber, cosmetics, and medicine. In this study, sequential electrochemical and chemical multi-polymerization of catechol was investigated for environmental pollution abatement. The effect of operating parameters like catechol concentration (2–10 g/L), ammonium persulphate (APS) concentration (2–10 g/L) and reaction temperature (20–60 °C) were evaluated using response surface methodology. Catechol concentration was determined using HPLC in a gradient mobile phase. The electrochemical behavior of the polymer was investigated by cyclic voltammetry (CV). The structural and morphological properties of polycatechol were characterized by Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy with energy dispersive X-ray (SEM–EDX) analysis. It was observed from the SEM images a polymeric structure developed from a crystalline and heterogeneous structure when the APS concentration increased. Similarly, it was seen in SEM images that the polymers transitioned from a bulk and heterogeneous structure to a homogeneous structure as the temperature increased, and back to a heterogeneous structure as the catechol concentration increased. It was also found that catechol removal increased and reaction selectivity decreased by increasing the reaction temperature. The optimum operating conditions were found as 4 g/L catechol concentration, 9.5 g/L APS concentration, 30 °C reaction temperature with 100 cycles at 50 mV/s of electrochemical polymerization and 72 h of chemical polymerization. The results of this study show the potential of challenging new routes not only facile polymerization of organic monomers but also to decrease the undesirable pollutant concentration in the wastewater.
