Metal-organic frameworks have been widely used as photocatalytic materials. In this paper, a novel photocatalyst HSO 3 -MIL-53(Fe) with acidity regulating groups was successfully synthesized by the solvothermal method and applied to remove carbamazepine (CBZ) and ibuprofen (IBP). The photodegradation efficiency of vis/H 2 O 2 /HSO 3 -MIL-53(Fe) can reach 100% when the pH value is 8 or 9. The free radical capture experiment and electron paramagnetic resonance analysis proved that hole (h + ), hydroxide radical ( · OH), singlet oxygen ( 1 O 2 ), and superoxide Radical ( · O 2 - ) are the main active species for pollutants degradation . In the vis/H 2 O 2 /HSO 3 -MIL-53(Fe) system, the high pollutant degradation efficiency under alkaline conditions was attributed to two factors: (1) the acidity adjusting group -HSO 3 adjusts the pH value of the whole system, which is beneficial to the photo-Fenton process. (2) The photogenerated electrons of HSO 3 -MIL-53(Fe) can be captured by Fe (III), H 2 O 2 and O 2 to accelerate the reduction of Fe (III) and generate · OH, 1 O 2 , and · O 2 - . Besides, H 2 O 2 can also be activated by Fe (II) and Fe (III). The above processes synergistically improved the photocatalytic efficiency. Based on liquid chromatography-mass spectrometry (LC-MS) analysis, the possible degradation pathways of the two pollutants were proposed.

Sulfur dioxide (SO 2 ) is emerging as a double-edged molecule, while plays vital roles in food and biological system. However, the fast, highly sensitive, and versatile fluorescent probe still remains a tough challenge among current reports. Herein, we developed a novel aggregation-induced emission (AIE) fluorescent probe TPE-PN for specifically sensing SO 2 derivatives with high sensitivity (150 nmol/L) and rapid response time (10 s) based on intramolecular charge transfer (ICT) mechanism. And the fluorescence at 575 nm decreased tremendously with 31-fold after the probe was treated with HSO 3 − . Employing the probe, the accurate analysis of HSO 3 − was successfully realized in food samples, cells, plant tissues, and zebrafishes. Furthermore, we successfully demonstrate the eruption of SO 2 derivatives within plant during drought and salt stress processes. Therefore, probe TPE-PN illustrates significant potential for applications in food analysis and monitoring of SO 2 derivatives levels in biological systems under stress conditions.

Sulfur dioxide (SO2) is considered as the fourth gas signal molecule after nitric oxide (NO), carbon monoxide (CO) and hydrogen sulfide (H2S). It plays important roles in several physiological processes. Therefore, the design and synthesis of nanoprobes for the detection of SO2 derivatives in cells is of great significance. Herein, we report a new ratiometric fluorescence nanoprobe based on resonance energy transfer (RET) between biomass quantum dots (BQDs) and organic dye (DMI) for the detection of SO2 derivatives. The proposed ratiometric fluorescence assay allows the determination of HSO3− in the range of 1.0 to 225 μM with a detection limit of 0.5 μM. Importantly, the proposed ratiometric fluorescence nanoprobe exhibits a high photostability and good selectivity for HSO3− over other chemical species including H2S and biological mercaptans. Quantitation of HSO3− in cell lysates by using the nanoprobe is demonstrated.

Sulfur dioxide (SO 2 ) is a significant atmospheric pollutant and food additive, with excessive sulfite (HSO 3 − ) consumption linked to health risks such as respiratory and cardiovascular disorders. Reliable, sensitive detection of HSO 3 − is essential for food safety and environmental monitoring. Here, we present a novel fluorescent probe (HMQ) for the selective detection of HSO 3 − in biological and environmental samples. The probe exhibits a distinct “ON-OFF” fluorescence response due to a nucleophilic addition mechanism, enabling high selectivity for HSO 3 − over other anions. HMQ was successfully applied for detecting exogenous HSO 3 − in living cells and for monitoring sulfite contamination in food samples. Additionally, test strips impregnated with HMQ provide a simple and rapid method for detecting HSO 3 − (SO 2 ) in aqueous solutions and gaseous environments. The probe demonstrates excellent sensitivity, with linear fluorescence responses and high recovery rates in both food and serum samples. This work provides a versatile tool for sulfite detection, with potential applications in food safety, environmental monitoring, and disease research.

Fluorescent PVBTI and HPVBTI with D-π–A structure were synthesized and could sensitively and selectively sense bisulfite (HSO3–) in phosphate-buffered saline solution (pH 7.4) via a Michael-addition mechanism. The introduction of a cationic group in two sensors efficiently avoided the interference of common cations in environmental samples. PVBTI and HPVBTI had high-selectivity to HSO3– over other anions and cations and they could detect HSO3– with the low detection limits of 13.3 nM and 26.7 nM, respectively. Their sensing mechanism was confirmed by 1H NMR and LC–MS spectra. HSO3– was detected by two fluorescent sensors in tap water, lake water, river water, and paddy water with satisfactory results, suggesting that PVBTI and HPVBTI could be as the practical sensing platform for sensitive and selective analysis of HSO3– in the environment.

Bisulfite (HSO 3 − ) plays an important role in life activities. Abnormal content of HSO 3 − may cause cardiovascular, cancer and other diseases. Frequency upconverted luminescent (FUCL) probes are a class of anti-Stokes luminescent materials with long-wavelength excitation and short-wavelength emission properties, which offer advantages in a range of applications due to their higher sensitivity and photostability. In addition, FUCL imaging has the advantages of high tissue penetration depth and low photo-damage, thus, it is more suitable for fluorescence imaging. In this work, a FUCL probe based on an xanthene fluorophore was designed and synthesised to detect HSO 3 − . The Probe PT-1 could respond to HSO 3 − and had high selectivity and sensitivity. It also exhibited a quenched FUCL signal. The detection limit of FUCL concerning HSO 3 − was 43 nM (λ ex = 730 nm), which is half the detection limit achieved under traditional excitation (93 nM, λ ex = 643 nm). Cell fluorescence imaging showed that PT-1 could effectively target mitochondria and monitor endogenous/exogenous HSO 3 − in living cells. More importantly, PT-1 was successfully used to monitor the level of HSO 3 − in mice with drug-induced liver injury through FUCL imaging.

HSO 3 − is an important reactive sulfur species that maintains the normal physiological activities of living organisms and participates in a variety of redox homeostatic processes. It has been found that changes in HSO 3 − levels is closely related to the heat stroke phenomenon of the organism. Heat stroke causes damage to normal cells, which in turn causes damage to the body and even death. It is crucial to accurately monitor and track the physiological behavior of HSO 3 − during heat stroke. Herein, a ratiometric multifunctional fluorescent probe DRM-SO 2 with dual-targeting ability to rapidly and precisely recognize HSO 3 − being constructed based on the FRET mechanism. DRM-SO 2 has extra Large Stokes shift (216 nm), very high sensitivity (DL = 12.2 nM), fast response time and good specificity. When DRM-SO 2 undergoes Michael addition with HSO 3 − , the fluorescence emission peak was blue-shifted from 616 nm to 472 nm, and a clear ratiometric signal appeared. The interaction between lysosomes and mitochondria in maintaining cellular homeostasis was investigated by the dual-targeting ability of the probe using HSO 3 − as a mediator. DRM-SO 2 achieved successful targeting and real-time monitoring of exogenous and endogenous HSO 3 − in the cells. More importantly, imaging experiments in heat stroke mice revealed high HSO 3 − expression in intestinal tissues. This provides new ideas and research tools for early prevention of heat stroke-induced diseases such as intestinal injuries. In addition, the semi-quantitative monitoring experiments for paper-based visualization of HSO 3 − make the probe promising for the design of portable detectors.

In this work, a water-soluble cationic fluorescent probe with AIE features exhibited unique sensing of charge-diffuse anions, namely, SCN − , PF 6 − , and HSO 3 − via ionic interactions and the subtle cooperation of the tunable hydrophobicity . The effect of the fatty chain length on the cationic probes indicated that the sensitivity and selectivity of the probes can be rationally improved by switching their aggregation tendency (hydrophobic effect) in water or by integrating them in the form of a fluorescence chemosensor array. SEM images suggest that different morphologies were formed in the anion-recognition-triggered self-assemblies of the probes, which can be attributed to the different anion molecular geometries. Additionally, the precipitation of the SCN − -recognition complex provided a new insight to the separation of anions from an aqueous environment .
