Recent developments in the creation of a single molecular sensing tool for ternary iron (III), chromium (III), aluminium (III) ionic species: A review

Abstract

Rational design of a molecular sensing tool is an important topic in molecular recognition, signalling, and optoelectronics that has piqued the interest of chemists, biologists, and environmental scientists. Approximately 150 years have passed since the beginning of the fluorescent chemosensor sector. Due to the paramagnetic properties of Cr3+ and Al3+, it is tough to prepare a photoluminescence plug‐in detector. Most dye‐based Al3+ sensors must be utilized in organic or mixed solvents for robust hydration of Al3+ in water. The sophisticated molecular design of sensors, conversely, allows for the detection of these metal ions in aqueous medium. The design of chemosensors using various fluorophores and their mechanisms of action have been thoroughly discussed. A literature survey covering the design of chemosensors and their mechanisms of action have been thoroughly discussed covering the period 2010–2022 and that was carried out including innovative and exemplary activities from numerous groups throughout the world that have significantly contributed to this sector. The most important advantages of these probes are their aqueous solubility and quick response with outstanding selectivity and sensitivity for temporal distribution with high fidelity of metals in living cells.

Azobenzene-Containing Schiff-Bases—Syntheses and Dyes Applications

“…But they can also play a great role in the formation of liquid crystals [68][69][70]. In the case of ions sensors in water, which may be dangerous for health, advanced research was made for easy tools for sensing them, including colorants [71][72][73][74]. But azo moieties, known for their coloring properties and coupled to Schiff bases known to complex ions, can give excellent results.…”

Smart and intelligent optical materials for sensing applications

“…The author discussed that PLNPs has varying applications such as in biosensing, cancer therapy, bioimaging, and cell tracking. Saha and Alam [22] surveyed literature covering the period from 2010 to 2022 on single molecular sensing tools for different metal ions. Sabuli et al [23] discussed the synthesis and fundamental features of colorimetric and fluorescence sensors produced by nanomaterials rich in carbon compounds, identifying various food contaminants such as mycotoxins, pathogens, and microorganisms.…”

Strategies for Improving Selectivity and Sensitivity of Schiff Base Fluorescent Chemosensors for Toxic and Heavy Metals

“…Quite a few review papers have been dedicated to the field of chemosensors for heavy metal ions detections in environmental and biological applications in recent years [14][15][16][17][18][19][20][21][22]. Some of them have focused on a single major fluorophore building block to track different ions.…”
