Chemodosimeters and chemoreactands for sensing ferric ions

Structural Features of a Family of Coumarin–Enamine Fluorescent Chemodosimeters for Ion Pairs

“…The yields for [Zn (7) 2 ] and [Zn(3) 2 ] were 85.9 mg (0.19 mmol, 52%) and 100.2 mg (0.14 mmol, 63%), respectively. 1D and 2D NMR spectra, IR spectra, and X-ray tables for [Zn (3) The Supporting Information is available free of charge at https://pubs.acs.org/doi/10.1021/acs.inorgchem.1c01734.…”

“…Advances in chemical analysis rely heavily on the design of molecular systems that recognize other molecules and respond to their presence with a macroscopic change in their properties (chemosensors) . The use of chemodosimeters , i.e., compounds that react covalently and irreversibly with their targets to form a new species with different properties than the original molecule (e.g., colorimetric or fluorometric signature), is a strategy that is less well explored in the sensor community. , Chemodosimeters can afford uncommonly high selectivity toward their targets by coupling with chemical cascade methods for response amplification. This approach has had immediate applications for analytical purposes, but it has also proven fruitful further afield, e.g., in the development of novel stimuli-responsive materials …”

Low Molecular Weight Fluorescent Probes (LMFPs) to Detect the Group 12 Metal Triad

“…Aggregation-induced emission (AIE) has become a popular mechanism exploited for sensors often used in chemodosimeter and chemoreactand type molecular probes. A recent review covers the use of chemodosimeters (non-reversible covalent bonds and chemoreactands with reversible covalent bonds), whereby, the optical properties were different from the bound and unbound chemical adducts [53]. Chatterjee and coworkers have prepared chemodosimeter 33 to detect organic and inorganic Hg 2+ species, Figure 14 [193].…”

“…In addition to these mechanisms, the underlying principles of molecular recognition and disclosure of analytes have also been extensively reviewed [42][43][44][45][46][47][48][49][50][51][52]. The review articles can be broad, covering a range of metals or probes, or could be very specific, highlighting the work on one particular cation, such as Fe 3+ [53], a specific fluorescent mechanism, such as excimer formation [54], or a specific type of chromophore, for example, squaraine dyes [55]. Alternatively, reviews might highlight the different probes within a given period [56].…”

A Multifunctional 3D Supermolecular Co Coordination Polymer With Potential for CO2 Adsorption, Antibacterial Activity, and Selective Sensing of Fe3+/Cr3+ Ions and TNP

“…Fe 3+ is an abundant and essential transition metal for biological organisms, and plays an important role in biological processes, such as enzymatic reactions, nitrogen fixation in nitrogenases, and oxygen transport. It is also well known that inadequate or excess iron concentration can induce serious health problems including anemia, Alzheimer's disease, liver and kidney damage, diabetes and heart disease, mitochondrial DNA damage (Harigae, 2018;VanderMeulen and Sholzberg, 2018;Wallace et al, 2018;Sahoo and Crisponi, 2019;Fan et al, 2020). Similarly, Cr 3+ has mutagenicity and cytogenetic toxicity, the scarcity or excess uptake of Cr 3+ results in cardiovascular diseases and diabetes, mutations or malignant cells (Paul et al, 2015;Zhang et al, 2015;Dong et al, 2016;, so it is urgent and necessary to detect metal ion pollutants in solution for the human security and environmental protection.…”
