A colorimetric, NIR, ultrafast fluorescent probe for ferric iron detection based on the PET mechanism and its multiple applications

Abstract

Since ferric iron (Fe3+) plays an important role in enzymatic catalysis, cell metabolism and oxygen transport in hemoglobin, many fluorescent probes have been developed to detect Fe3+. However, designing and...

One-pot in situ functionalization of cellulose in a CO2 switchable solvent for the fluorescent detection of Fe3+

“…6(c)). 2,59,[63][64][65][66][67][68] Thus the application of this cellulose-based uorescent material as a uorescent probe for the quantitative detection of Fe 3+ in domestic water such as mineral water and tap water was demonstrated. As shown in Fig.…”

Small-Molecule Fluorescent Probes for Binding- and Activity-Based Sensing of Redox-Active Biological Metals

“…129−132 Dyes 51 and 52 (DCA-Mln) were prepared by combining malononitrile with triphenylamine and benzopyran derivatives respectively. 133,134 For these two probes, the two nitrile groups coordinate to ferric ions leading to fluorescence quenching. Probe 53, a coumarin-based pyrazoline dye linked to triphenylamine, was reported by the Zhang and Yang groups.…”

“…Probes 47 – 50 incorporate N -containing aromatic systems as the fluorescent units, which undergo fluorescence quenching when Fe­(III) binds to their specific recognition sites. − Dyes 51 and 52 (DCA-Mln) were prepared by combining malononitrile with triphenylamine and benzopyran derivatives respectively. , For these two probes, the two nitrile groups coordinate to ferric ions leading to fluorescence quenching.

Facile synthesis of a fluorescent probe based on a terbium-based metal–organic framework for selective detection of Fe(iii) and Al(iii)

“…1 The ferric ion (Fe 3+ ) is an important metal ion that participates in many physiological processes, such as metabolic processes, enzymatic reactions, nucleic acid and hemoglobin synthesis, oxygen transport and electron transfer etc. [2][3][4][5][6] Thus, its excess and deficiency in an organism can result in apoptosis, anemia, heart disease and tissue damage. [7][8][9][10] In contrast, the aluminum ion (Al 3+ ) is highly toxic to plants since it can hinder the uptake of Ca 2+ .…”
