“…The constant k was 1.29 × 10 4 M −1 , and the LOD of U-CMNDI to Br − was 5.49 μM, comparable to levels of the previous literature. 34 Moreover, U-CMNDI exhibited fluorescence turn on toward iodide ions (I − ). Gradually, 1 × 10 −3 M of I − aqueous solution was added to 3 mL of the U-CMNDI suspension with a concentration of 0.2 mg/mL.…”

It can provide ideas for the use of uranium elements in the treatment of spent fuel from nuclear wastewater to explore the application potential of uranium element. Thus, it is necessary to research the structure and properties of a novel uranyl coordination polymer (CP) for uranium recovery and reuse. Herein, we designed and prepared a new uranyl CP U-CMNDI based on UO 2 2+ and H 2 CMNDI (H 2 CMNDI = N, N′-bis-(carboxymethyl)-1,4,5,8-naphthalenediimide). Structural analysis shows that two uranyl ions are connected by two parallel deprotonated CMNDI ligands to form a discrete uranyl dimer structure. U-CMNDI can act as a potential stimulus-responsive halide ion sensor by a fluorescence "turn on" response in water. The limit of detection for fluoride (F − ), bromide (Br − ), iodide (I − ), and chloride (Cl − ) is 5.00, 5.32, 5.49, and 5.73 μM, respectively. The fluorescence "turn on" behavior is based on the photoinduced electron transfer (PET) mechanism between halide ions and electron-deficient NDI cores. In addition, U-CMNDI demonstrates a color response to ultraviolet light, exhibiting reversible photochromic behavior with a notable color change. The color change mechanism can contribute to the PET process and the radical process.

“…9,10 Over the past few decades, colorimetric and fluorogenic sensing systems have emerged as an efficient alternative to the traditional instrument-based detection processes. [8][9][10][11][12][13][14][15][16][17] These techniques have the advantages of costeffectiveness, simple synthesis, easy purification, and ease of operation. Many attempts have been made in recent years to sense various anions and cations using chromogenic and fluorogenic methods.…”

Sulfite is widely used as an antioxidant additive and preservative in food and beverages. Abnormal levels of sulfite in the body is related to a variety of diseases. There are strict rules for sulfite intake. Therefore, to monitor the sulfite level in physiological and pathological events, there is in urgent need to develop a rapid, accurate, sensitive, and non−invasive approach, which can also be of great significance for the improvement of the corresponding clinical diagnosis. With the development of fluorescent probes, many advantages of fluorescent probes for sulfite detection, such as real time imaging, simple operation, economy, fast response, non−invasive, and so on, have been gradually highlighted. In this review, we enumerated almost all the sulfite fluorescent probes over nearly a decade and summarized their respective characteristics, in order to provide a unified platform for their standardized evaluation. Meanwhile, we tried to systematically review the research progress of sulfite small−molecule fluorescent probes. Logically, we focused on the structures, reaction mechanisms, and applications of sulfite fluorescent probes. We hope that this review will be helpful for the investigators who are interested in sulfite−associated biological procedures.
