“…These organic compounds, characterized by an imine (-C=N-) functional group formed by the reaction between an amino group and an aldehyde or ketone functionality, have a central role in coordination chemistry and are considered as privileged ligands for complexation with metal ions [17]. The so-formed complexes may exhibit catalytic activity, fluorescence and magnetic behavior, thus providing qualitative and/or quantitative responses [11,18,19]. In this context, systematic theoretical studies can provide useful information about the possible complexation mechanisms and also allow for a comparison with experimental results.…”

Schiff bases (SBs) are important ligands in coordination chemistry due to their unique structural properties. Their ability to form complexes with metal ions has been exploited for the environmental detection of emerging water contaminants. In this work, we evaluated the complexation ability of three newly proposed SBs, 1–3, by complete conformational analysis, using a combination of Molecular Dynamics and Density Functional Theory studies, to understand their ability to coordinate toxic heavy metal (HMs) ions. From this study, it emerges that all the ligands present geometries that make them suitable to complex HMs through the N-imino moieties or, in the case of 3, with the support of the oxygen atoms of the ethylene diether chain. In particular, this ligand shows the most promising coordination behavior, particularly with Pb2+.

“…These complexes often exhibit valuable properties, such as catalytic activity, fluorescence, and magnetic behavior. In addition to their coordination chemistry, Schiff bases also find applications in organic synthesis and medicinal chemistry [4,5]. They can be used as intermediates in preparing various organic compounds and are commonly employed in synthesizing dyes, pigments, and pharmaceuticals.…”

Toxic cations, including heavy metals, pose significant environmental and health risks, necessitating the development of reliable detection methods. This review investigates the techniques and approaches used to strengthen the sensitivity and selectivity of Schiff base fluorescent chemosensors designed specifically to detect toxic and heavy metal cations. The paper explores a range of strategies, including functional group variations, structural modifications, and the integration of nanomaterials or auxiliary receptors, to amplify the efficiency of these chemosensors. By improving selectivity towards targeted cations and achieving heightened sensitivity and detection limits, consequently, these strategies contribute to the advancement of accurate and efficient detection methods while increasing the range of end-use applications. The findings discussed in this review offer valuable insights into the potential of leveraging Schiff base fluorescent chemosensors for the accurate and reliable detection and monitoring of heavy metal cations in various fields, including environmental monitoring, biomedical research, and industrial safety.
