Insights into the surface and redox properties of single-walled carbon nanotube—cobalt(II) tetra-aminophthalocyanine self-assembled on gold electrode

Abstract

This paper describes for the first time the electrochemical properties of redox-active selfassembled films of single-walled carbon nanotubes (SWCNTs) coordinated to cobalt(II)tetra-aminophthalocyanine (CoTAPc) by sequential self-assembly onto a

Adsorption of cobalt (II) 5,10,15,20-tetrakis(2-aminophenyl)-porphyrin onto copper substrates: Characterization and impedance studies for corrosion inhibition

“…A smaller capacitance predicts a smaller charge on the coating/electrolyte interface and therefore a smaller concentration difference in the electrolyte solution and of course less diffusion of ions [49].…”

Chemically Modified Carbon Nanotubes: Derivatization and Their Applications

“…Rutin modified MWCNTs on the surface of GCE were prepared and used towards the electrooxidation of hydroxylamine [100]. SAMs of SWCNTs with cobalt (II) tetraminophthalocyanine on gold electrode have been prepared and applied in the determination of dopamine and epinephrine [101,102]. Phenothiazine derivatives, Azure C and MWCNTs co-immobilized in the chitosan matrix were used to develop amperometric sensor for the determination of NADH [103].…”

Electrochemical Sensing of Acyclovir at a Gold Electrode Modified with 2-Mercaptobenzothiazole–[5,10,15,20-tetrakis-(3-methoxy-4-hydroxyphenyl)porphyrinato]copper(II)

“…23 The advantages of SAM modified GE using different metallophthalocyanine complexes have been reported by Nyokong and coworkers for the determination of several analytes. [24][25][26][27][28] As part of our investigations, we report strategies The electrooxidation of acyclovir (ACV) was studied using a gold electrode (GE) modified with a self-assembled monolayer of 2-mercaptobenzothiazol (MBZ) and [5,10,15,20- to link metalloporphyrin, TMHPP Cu(II) to the MBZ modified GE through adsorption. To the best of our knowledge, no studies on the electrochemical behavior of ACV and its quantitative determination at MBZ/TMHPP Cu(II)-modified GE have been reported yet.…”
