We posit that this spectral disparity is intricately linked to the distinct heteroatoms present within the cyclic structures of these compounds. Our meticulous analysis, informed by the contextualization of our findings within the existing literature, not only advances our understanding of the electronic properties of compounds 4a-h but also underscores the potential impact of subtle structural modifications on their absorption characteristics. These insights bear significance not only for fundamental research in molecular electronics but also for the rational design of compounds with tailored electronic properties for specific applications. The voltammograms of the studied compounds exhibit a consistent profile, featuring both oxidation and reduction peaks (Figure ). The appearance of oxidation peaks (anodic peaks) in the voltammograms may be attributed to the oxidation of nitrogen atoms within the molecular structures. Conversely, the cathodic peak observed in the voltammograms is likely associated with the reduction of the ketone function (C=O). Acrylohydrazide derivatives undergo oxidation and reduction processes on the platinum electrode. 𝑚𝑉 (assuming a mono-electronic or bi-electronic process with n=1 or n=2, respectively) suggest a quasi-reversible process.
