“…21,22 Recently, inductively coupled plasma mass spectrometry, atomic absorption spectrometry, gas chromatography, and high-performance liquid chromatography have been used to detect Hg 2+ and Ag + ions. 23 Unfortunately, because of the increasing equipment costs, sophisticated procedure processes, and skilled supervision, the widespread use of the traditional methods mentioned above has been limited. Fluorescent probe technologies provide significant advantages over these advanced systems for Hg 2+ and Ag + detection, along with excellent sensitivity, high selectivity, ease of operation, low cost, and real-time sensing.…”

“…In recent literature, several fluorescent probes are often used to monitor environmental and biological samples for Hg 2+ and Ag + ions. 23 However, these luminous probes have some disadvantages, such as low sensitivity and a high limit of detection (LOD), which limits their practical applicability. As a result of the aforementioned challenges, as well as the prospective application of luminous chromophores, the development of advanced and novel luminous probes with many more advantages in the domains of agricultural, environmental, and biological studies remains promising and significant.…”

It is critical to design a novel and simple bifunctional sensor for the selective and sensitive detection of ions in an aqueous media in environmental samples. As a result, in this study, tetraphenylethene hydrazinecarbothioamide (TPE-PVA), known as probe 1, was successfully synthesized and characterized as having impressive photophysical phenomena such as aggregation-induced emission (AIE) and mechanochromic properties by applying mechanical force to the solid of probe 1. The emission of the solid of probe 1 changed from turquoise blue to lemon yellow after grinding, from lemon yellow to parakeet green after annealing at 160 °C, and to arctic blue after fuming with DCM. Such characteristics could lead to a variety of applications in several fields. The probe was implemented and demonstrated remarkable selectivity and sensitivity toward mercury(II) and silver(I) ions by substantially switching off emission over other cations. Following an extensive photophysical analysis, it was discovered that detection limits (LOD) as low as 0.18344 and 0.2384 μg mL –1 for Hg 2+ and Ag + , respectively, are possible with a quantum yield (Φ) of 2.26. Probe 1 was also explored as a Hg 2+ and Ag + paper strip-based sensor and kit for practical use. The binding mechanisms of probe 1 (TPE-PVA) with Hg 2+ and Ag + were confirmed by 1 H NMR titration. These results could lead to the development of reliable onsite Hg 2+ and Ag + fluorescent probes in the future.

Mercury is unacceptable as a whitening agent in cosmetics because it is highly toxic and much harmful to the digestive, respiratory, circulatory, and nervous systems of humans. Therefore, it is of fundamental and practical importance to detect whether the concentration of mercury in cosmetics meets national standards. In this work, a new way for the simple visual and rapid colorimetric detection of Hg2+ using gold nanoparticle (AuNPs) modified with amrinone (3‐amino‐5‐pyridin −4‐yl‐1H‐pyridin‐2‐one, ALN) is proposed and characterized by transmission electron microscopy (TEM), dynamic light scattering (DLS), UV‐vis, Fourier transform infrared (FTIR) and analyzed of Gaussian16w and Multiwfn simulations. The solution colors changed from wine‐red to gray‐blue with increasing Hg2+ concentration resulting from the agglomeration of AuNPs with favorable anti‐interference and selectivity. The limit of detection (LOD) is 0.8 μmol/L by the unaided eye, and 18.2 nmol/L by UV‐vis spectroscopy with the excellent linear relationship (R2=0.9935) in the range of 0.0∼6.0 μmol/L (Hg2+ concentration), showing that AuNPs modified with ALN can serve as the quantitative determination of Hg2+. After testing actual samples, it is found that the test method can be practically applied to the monitoring of heavy metal mercury in cosmetics.

A Review on Metal Ion Sensors Derived from Chalcone Precursor

2022

Disclosure of new molecular probes as chromogenic and fluorogenic cation sensors is scientifically exigent work. Recently chalcone derivatives gained more attention because of their structural variability. A suitable donor and acceptor groups separated by delocalized π-orbitals display excellent chromogenic and fluorogenic properties because of intramolecular charge transfer (ICT). These designed molecular frameworks provide the coordination sites to the incoming metal ions results in small changes in the optical properties. In a typical sensing behavior, coordination leads to a large conjugation plane with the probe resulted in hypo/hyperchromic shifts or red/blue shifts. In this review, we tried to converge the reported chalcone-derived sensors and explored the design, synthesis, metal ion sensing mechanism, and practical application of the probes. We expect that this review gives a basic outline for researchers to explore the field of chalcone-based sensors further.
