Electrochemical Characterization of Bis-(10Hphenothiazin-3-yl)-methane Derivatives Obtained by Microwave Assisted Organic Synthesis

摘要

Microwave assisted heating in pressurized systems is proved to be an efficient technique for the preparation of bis(10Hphenothiazin-3-yl)-methane and bis-(10Hphenothiazin-3-yl)-phenyl-methane derivatives by the condensation of phenothiazine with aldehydes in acidic media Redox activity of bis-(10Hphenothiazin-3-yl)-methane derivatives was demonstrated by cyclic voltammetry experiments and modified electrodes were prepared by adsorption of these compounds on spectrographic graphite. The cyclic voltammograms recorded for a range of potential scan rates (10-400 mV s(-1)) showed a linear dependence of the peak currents on the electrode potential scan rate. The estimated electrochemical parameters show redox activity, stability and good adsorption properties on graphite.
