“…The furan-2-carbonyl chloride modified rhodamine B derivative 36 selectively forms a complex with Fe 3+ in 1:1 ratio and shows significant fluorescence enhancement at 582 nm that allows to detect Fe 3+ down to 0.437 μM [44]. The pyridine-type rhodamine B fluorescent probes 37 and 38 are developed to detect Fe 3+ down to 0.067 μM and 0.345 μM, respectively [45]. Its analytical applicability has been tested by monitoring Fe 3+ concentrations in various real water samples and live cells.…”

Iron(III) is well-known to play a vital role in a variety of metabolic processes in almost all living systems, including the human body. However, the excess or deficiency of Fe3+ from the normal permissible limit can cause serious health problems. Therefore, novel analytical methods are developed for the simple, direct, and cost-effective monitoring of Fe3+ concentration in various environmental and biological samples. Because of the high selectivity and sensitivity, fast response time, and simplicity, the fluorescent-based molecular probes have been developed extensively in the past few decades to detect Fe3+. This review was narrated to summarize the Fe3+-selective fluorescent probes that show fluorescence enhancement (turn-on) and ratiometric response. The Fe3+ sensing ability, mechanisms along with the analytical novelties of recently reported 77 fluorescent probes are discussed.

“…From Figure b, the maximum value of absorption of clip 1 ‐Fe 3+ appeared at 0.5268, which indicated that the stoichiometric ratio of the clip 1 ‐Fe 3+ is 1 : 1. The association constant was estimated to be 3.63×10 3 M −1 according to Benesi‐Hildebrand Formula (see supporting information):

true normalF - normalF_{0} = [Fe^{3 +}] (F_{\max} - F_{0}) / (1 / K_{normala} + [Fe^{3 +}])

A New Fluorescent Sensor for Fe³⁺ Based on Glycoluril Molecular Clip

et al. 2020

The application of fluorescent method to metal ions detection features high sensitivity, simple operation and real‐time monitoring. A 2,7‐dihydroxynaphthalene‐functionalized dimethyl glycoluril (called clip 1) was synthesized, using a relatively simple method. And it is fully characterized by 1H NMR, 13C NMR, HR‐MS and single crystal X‐ray diffraction. The recognition properties of molecular clip 1 were analyzed systematically toward several metal ions using fluorescence spectroscopy, and it was found that molecular clip 1 is selective and sensitive to Fe3+. At the same time, the clip 1 shows good anti‐interference ability when other metal ions existed. The limit detection of Fe3+ is 3×10−7M. The fluorescence of clip 1 was quenched apparently by Fe3+, which was speculated to be caused by ligand–metal charge transfer mechanism (LMCT). As a new fluorescence probe for Fe3+ ion, it may expanded the application of glycoluril molecular clips.
