“…Some rhodanine derivatives have antimicrobial properties [4][5][6]. Rhodanine derivatives can be used as pan-assay interference compounds for biological samples [7][8][9], for water treatment in efficient removal of HMs cations [10], and as fluorescence sensors for organic compounds [11] or HMs (Fe [12], Hg [13][14][15], and Cu [13]; Ag [15,16], Zn [17], and Cd [17] targets). There are no reported electrochemical sensors based on CMEs by using rhodanine derivatives for the detection of HMs.…”

Electrochemical and spectral studies of benzylidenerhodanine (BR) were performed in order to develop new sensors for heavy metals (HMs) based on chemically modified electrodes (CMEs). CMEs were obtained by cycling and by controlled potential electrolysis at different potentials and charges. Film formation was demonstrated by recording the CV curves of CMEs in transfer solutions containing ferrocene in 0.1 M TBAP/CH3CN. BR-CMEs were used for the analysis of HMs. Samples of Cd(II), Pb(II), Cu(II), and Hg(II), each possessing concentrations between 10−7 and 10−5 M, were analyzed by using CMEs prepared in different conditions. The most intense signal was obtained for the Pb(II) ion. These BR-CMEs can be used for the analysis of Pb(II) in monitored waters. An electrochemical study was performed at different concentrations of BR in 0.1 M TBAP/CH3CN on a glassy carbon electrode by differential pulse voltammetry, cyclic voltammetry, and rotating disk electrode voltammetry. The complexation ratio in the homogeneous solution has been established by the Mollard method in acetonitrile solutions.

“…In this sense, an MLG with INHIBIT logic gate can be built considering the presence of ions Mg 2+ and F − as input "1" and their absence as input "0" and considering the emission at 631 nm as output "1" and their lack as output "0" (Scheme 12b,c). Another example of a halide-promoting decomplexation for the elaboration of an MLG was described by David et al [183]. The authors designed the rhodanine derivative 27 to detect Ag + e I − (Scheme 13a).…”

Optical detection devices have become an analytical tool of interest in diverse fields of science. The search for methods to identify and quantify different compounds has transposed this curiosity into a necessity, since some constituents threaten the safety of life in all its forms. In this context, 30 years ago, Prof. Prasanna de Silva presented the idea of sensors as Molecular Logic Gates (MLGs): a molecule that performs a logical operation based on one or more inputs (analytes) resulting in an output (optical modification such as fluorescence or absorption). In this review, we explore the implementation of MLGs based on the interference of a second input (second analyte) in suppressing or even blocking a first input (first analyte), often resulting in INHIBIT-type gates. This approach is interesting because it is not related to attached detecting groups in the MLG but to the relation between the first and the second input. In this sense, flexible and versatile MLGs can be straightforwardly designed based on input selection. To illustrate these cases, we selected examples seeking to diversify the inputs (first analytes and interfering analytes), outputs (turn on, turn off), optical response (fluorescent/colorimetric), and applicability of these MLGs.

“…Silver ions bioaccumulate in the human body via the regular food chain and drinking water. Also, in the case of aquatic environments, it is highly toxic and fatal to organisms if the concentration of silver is higher than 1.6 nM. − At the same time, excess silver ions in the human body can cause a variety of negative health consequences, including damage to the respiratory system, brain, and central nervous system. − Furthermore, excessive silver absorption even leads to death of internal organs and creates severe pains in the stomach and kidneys. − These are mostly the result of the mushrooming of companies across the world, particularly those producing electrical, electronic, and photographic products, which have serious impacts on both people and the environment. As a result, a simple artificial probe for precise detection of silver ions is very desirable and critical in the current situation.…”

Three simple dipodal artificial acyclic symmetric receptors, SDO, SDM, and SDP, driven by positional isomerism based on xylelene scaffolds were designed, synthesized, and characterized by 1 H NMR, 13 C NMR, and mass spectroscopy techniques. Probes SDO, SDM, and SDP demonstrated selective detection of Ag + metal ions and amino acid L-histidine in a DMSO−H 2 O solution (1:1 v/v, HEPES 50 mM, pH = 7.4). The detection of Ag + metal ions occurred in three ways: (i) inhibition of the photoinduced electron-transfer (PET) process, (ii) blueshifted fluorescence enhancement via the intramolecular chargetransfer (ICT) process, and (iii) restricted rotation of the dangling benzylic scaffold following coordination with a Ag + metal ion. Job's plot analysis and quantum yields confirm the binding of probes to Ag +
