“…Both excess and deficiency of Fe 3+ can destabilize cellular homeostasis and lead to various diseases, such as iron deficiency anemia (IDA), arthritis, liver injury, renal failure, diabetes, Parkinson’s and Alzheimer’s diseases, and even cancers. − Hence, determination of Fe 3+ is key to the early diagnosis of these diseases. Among various detection strategies, fluorescence-based methods have attracted increased attention because of their high sensitivity, diverse selectivity, and easy operation. − Over the last few decades, rhodamine B (RhB) and its derivatives have been used for Fe 3+ detection owing to their photophysical properties, such as high molar extinction coefficient and inertness to pH, as well as high fluorescence quantum yield. − However, RhB-based sensors intrinsically suffer from poor selectivity and low photostability as a result of interference with other trivalent metal ions, especially Cr 3+ , and tedious functional group modification, as well as short fluorescence lifetime. , To overcome the shortcomings of organic dye-based detection of Fe 3+ , some researchers developed inorganic nanoparticle-based sensors, such as carbon dots (CDs) and semiconductor quantum dots (SQDs). − These inorganic nanoscale dots possess outstanding properties, including good photostability, excellent biocompatibility, and cell membrane permeability based on their small size, tunable surface functionality, and long-term resistance to photobleaching. Despite the highly anticipated potential of these nanosensors, some issues, including short-wavelength emission, small Stokes shift, low quantum yield, and poor selectivity, have limited their applications in Fe 3+ detection.…”

A Metal–Organic Framework as Selectivity Regulator for Fe³⁺ and Ascorbic Acid Detection

Ferric ion (Fe3+) plays a vital role in cellular homeostasis. However, the detection of Fe3+ with rhodamine B (RhB) has potential problems, such as poor selectivity and low photostability. To address these problems, we rationally designed an RhB@MOF nanocomposite-based “on–off–on” fluorescent switching nanoprobe for highly sensitive and selective detection of Fe3+ and ascorbic acid. This RhB@MOF nanoprobe was prepared through a facile one-pot synthesis. Here MOF served as a selectivity regulator for the detection of Fe3+. By embedding RhB into the porous crystalline MOF, enhanced photostability and fluorescence lifetime of RhB to Fe3+ were achieved. The as-prepared RhB@MOF was demonstrated to be an ultrasensitive and selective nanoprobe for the detection of Fe3+ in human serum and ascorbic acid in rat brain microdialysate. Furthermore, inner filter effect (IFE) and photoinduced electron transfer (PET) were proposed and discussed to explain the selectivity and sensitivity of RhB to Fe3+ against other interfering substances. Our novel “on–off–on” nanoprobe provides insight into the rational design of MOF-based biosensors for selective and sensitive detection of analytes.

Metal−organic frameworks (MOFs)-based sensors for monitoring toxic substances in wastewater have attracted great attention due to the efficient and reliable performance. Here, we has synthesized two novel zinc-based MOFs [Zn(ttb) 2 (H 2 O) 2 ] n (Zn1-ttb) and {[Zn(ttb) 2 ]•0.5CH 3 CN} n (Zn2-ttb) through changing the polarity of reaction solvents and finally obtained target 2D MOF material [Zn(ttb)(bdc) 0.5 ] n (Zn3-ttb-bdc) by successfully introducing an ancillary ligand H 2 bdc (Httb = 1-(triazo-1-ly)-4-(tetrazol-5-ylmethyl)benzene, H 2 bdc = 1,4-benzenedicarboxylic acid). As-prepared Zn3-ttb-bdc exhibits high water and chemical stability as well as excellent fluorescence property. Due to the −COOH binding sites from H 2 bdc, Zn3-ttb-bdc shows high sensitivity and a rapid luminescent response to a representative organic micropollutant trinitrophenol (TNP) and inorganic pollutants (Fe 3+ and Cr 2 O 7 2− ) in wastewater. The mechanisms of multifunctional detection abilities of Zn3-ttb-bdc toward different types of pollutants are further studied. This work presents the structural design in preparing MOF materials for multifunctional detection performance, thus opening new perspectives for emerging MOF-based sensors as environmental monitors.

“…Herein, we constructed a new ratiometric fluorescence sensor by encapsulating red-emitting rhodamine B (RhB) in a zirconium-based MOF (Zr-MOF) for detecting Al 3+ in an aqueous medium. The high molar extinction coefficient, inertness to pH, low toxicity, and high fluorescence quantum yield of RhB endow it as an ideal fluorescence reference. − Zr-MOFs exhibit advanced superiority to act as chemical sensors because of their moderate pore size, high water stability, and nontoxic nature. Further, Zr 4+ , as a kind of hard acid, is usually coordinated with hard base sites such as carboxylic acid oxygen, and the phenolic hydroxyl functional unit can be fixed on the pore surface of the MOF to provide a binding site for Al 3+ . , It is known that a Zr-MOF-based turn-on ratiometric fluorescence sensor for Al 3+ detection has not been reported yet.…”

Dual-Emission Zr-MOF-Based Composite Material as a Fluorescence Turn-On Sensor for the Ultrasensitive Detection of Al³⁺

et al. 2020

In this work, a novel zirconium-based metal–organic framework (MOF) composite material, UiO-(OH)2@RhB, has been solvothermally prepared with zirconyl chloride octahydrate, 2,5-dihydroxyterephthalic acid, and rhodamine B (RhB) for ratiometric fluorescence sensing of Al3+ ions in an aqueous medium. The luminescence measurement results showed that, at the single excitation wavelength of 420 nm, the fluorescence intensity of the ligand at 500 nm increased significantly in the case of Al3+, while that of RhB at 583 nm changed slightly, together with an apparent color change. Under optimal conditions, UiO-(OH)2@RhB exhibited an extraordinary sensitivity (10 nM), good selectivity, and a fast response (2 min) for Al3+. As far as we know, the limit of detection is superior to that of the current reported MOF-based Al3+ fluorescence sensors. The response mechanism suggested that −OH could capture Al3+ in water through coordination and high electrostatic affinity and achieved turn-on ratiometric fluorescence through the excited-state intramolecular proton transfer process and stable fluorescence of RhB. In addition, this sensor was also applied to actual food samples (grain beans), with the recoveries ranging from 89.08% to 113.61%. Such a turn-on ratiometric fluorescence sensor will provide a constructive strategy for the ultrasensitive detection of Al3+ in practical applications.
