“…22,23 Furthermore, metallophthalocyanine modified electrodes are efficient catalysts for redox reactions because they have a planar π-conjugated skeleton structure similar to biological molecules, such as chlorophyll and hemoglobin. 27 Hydrophobic metallophthalocyanines could aggregate in aqueous solutions owing to their π-conjugations with each other, whereas water-soluble metallophthalocyanines could be ordered on the electrode surface without aggregation.…”

“…In the literature, a few investigations in which metallophthalocyanines were used to modify the electrodes for BPA analysis were published. The linear ranges reported for BPA analysis were 8.75 × 10 -8 -1.25 × 10 -5 M, 14 7 × 10 -4 -3 × 10 -2 M, 25 1 × 10 -6 -8 × 10 -6 M, 26 and 5 × 10 -8 -4 × 10 -6 M. 27 All in these works the modified electrodes for BPA analysis have been investigated in basic or neutral media. In most of these studies, nanomaterials were also utilized for modification.…”

Pencil graphite electrodes modified with Co(II), Ni(II), Cu(II) and Fe(II) metallophthalocyaninetetrasulfonates (MePcTSs) were investigated for an electrochemical determination of bisphenol A (BPA). The electrochemical performances of the modified electrodes for different pH values in phosphate and the Britton-Robinson buffers were determined by cyclic voltammetry; the electrode performances were better in the Britton-Robinson buffer. NiPcTS and CoPcTS modifications of the electrodes had remarkable enhancements on their performances. The differential pulse voltammetry parameters for the electrodes were optimized, and we found that the electrochemical response versus the concentration of BPA is linear from 5.0 × 10(-7) to 1.0 × 10(-5) M for the NiPcTS and CoPcTS modified electrodes. The detection limits of these modified electrodes are 2.9 × 10(-7) and 4.3 × 10(-7) M, respectively, and the effects of interfering species are less than 5%. The results show that NiPcTS and CoPcTS modified pencil graphite electrodes could be used for electrochemical determinations of BPA for analytical purposes.

Non-aggregated axially disubstituted silicon phthalocyanines bearing electropolymerizable ligands and their aggregation, electropolymerizaton and thermal properties

A novel series of axially disubstituted silicon(iv) phthalocyanines bearing electropolymerizable ligands were designed and synthesized for the first time. The silicon(iv) phthalocyanines were characterized by various spectroscopic techniques as well as elemental analysis. The aggregation behavior of the SiPcs were examined in different solvents and at different concentrations in chloroform. In all the studied solvents and concentrations, the SiPcs were non-aggregated. The thermal behavior of the silicon(iv) phthalocyanines was also studied. The electropolymerization properties of the silicon(iv) phthalocyanines were investigated by cyclic and square wave voltammetry. This study is the first example of the electropolymerization of axially disubstituted silicon phthalocyanines. The type of axial ligand on the phthalocyanine ring did not show any effect on the absorption and thermal properties but influenced the electropolymerization of the phthalocyanines.
