Redox and Spectroscopic Investigations of Some Active Compounds

Literature survey reveals that the researchers have mostly used a single electrochemical technique for the investigation of the redox properties of compounds. However, for getting reliable information about the redox properties, it is obligatory to use a variety of electrochemical techniques as cyclic voltammetry provides a general portrait of the redox response; square wave voltammetry ensures the reversibility/quasi-reversibility and differential pulse voltammetry helps in the determination of number of electrons involved in oxidation or reduction processes. The voltammetric behavior of molecules also depends on the pH of the medium and their potential-pH diagrams can give useful insights about the stability of different forms of molecules. Moreover, the pH dependent redox behavior has a significant role in controlling the biocidal applications of different drugs. Based on these considerations, the redox mechanistic pathways of robustly electroactive compounds belonging to Schiff bases, quinones and naphthalene derivatives were studied in media of different pH.
