“…However, TPM dyes are recognized as potential environmental pollutants, prompting considerable research efforts to understand their physiochemical characteristics and devise effective strategies to mitigate their impact (Pillai et al, 2011;Petcu et al, 2016). In addition, they have gained attention in nontraditional usages, particularly in developing molecular devices by exploiting electrochemical switching (Ariga, 2006;Selvakumar, 2017;Toma, 2008;Ge et al, 2022).…”

The cyclic voltammetric method was employed to study the electrochemical behavior of aqueous crystal violet in the presence of cetyltrimethylammonium bromide, both below and above the critical micelle concentration. The cyclic voltammograms were highly sensitive to solution pH exhibiting well-defined oxidation and reduction peaks within the pH range of 1.76 to 2.29. The electrochemical potentials and currents indicate the involvement of a set of reactions responsible for the observed voltammograms. The diquinoid of N, N, N’, N’- tetramethylbenzidine was formed, which was reduced to N, N, N’, N’- tetramethylbenzidine. The presence of CTAB profoundly influenced the electrochemical behavior, and responses were found to depend on the dissolved states of CTAB. The electrochemical process was diffusion-controlled and followed a chemical-electrochemical-chemical (CEC) mechanism. J. Bangladesh Acad. Sci. 48(1); 75-83: June 2024

“…They are regarded as environmental hazards, and significant research efforts have been devoted to exploring their physiochemical properties aiming to find ways to minimize their environmental impacts [5,6]. However, in recent years TPM dyes have drawn much attention due to their prospect for versatile uses other than traditional ones, including developing switchable molecular devices by controlling their electrochemical properties [7][8][9][10]. It is also worth investigating whether the unusual electrochemical behavior is retained in organized media such as micellar systems and electrochemical responses correlate with the dissolved states of the surfactant in the presence of TPM dyes.…”

The electrochemical behavior of aqueous crystal violet in the presence of a nonionic surfactant, Triton X-100 (TX-100), was investigated using cyclic voltammetry. The cyclic voltammogram of crystal violet at a platinum electrode in an aqueous solution using 0.16 M NaCl as the supporting electrolyte was very sensitive to solution pH. In the pH range of 1.76 to 2.29, a well-defined voltammogram with one cathodic reduction peak and one anodic oxidation peak indicates unusual electrochemical reactions of crystal violet to yield the diquinoid of N,N,N’,N’-tetramethyl benzidine (TMBOx) upon oxidation, which is reduced through a two-electron process to N,N,N’,N’-tetramethyl benzidine (TMB). The cyclic voltammetric behavior of crystal violet in the presence of TX-100 surfactant, both below and above the critical micelle concentration, depends on the dissolved states of the surfactant. The electrochemical properties of crystal violet have been found to be diffusion controlled and dependent on TX-100 concentration. The electrochemical reaction is coupled with a preceding and a following chemical reaction and follows a CEC (chemical-electrochemical-chemical) mechanism. Interestingly, the unusual electrochemical reaction also occurs in the micellar system, and overall electrochemical behavior is dictated by the structure of crystal violet depending on the solution pH as well as the dissolved state of the surfactant. The findings of the present study may be useful to understand the host-guest chemistry of crystal violet and TX-100 at the molecular level.
