Therefore, the development of near-infrared (NIR) fluorescent probes with high sensitivity and selectivity for in vivo detection of Cys is significant. In this study, a water-soluble, NIR \"turn-on\" fluorescent probe (<strong>CQAI</strong>) is developed by integrating coumarin derivatives with acrylate moieties. The introduction of <em>N</em>-methylquinolinium into the fluorophore scaffold endows the probe with significantly enhanced water solubility and a remarkable Stokes shift of 255 nm. The fluorescence of <strong>CQAI</strong> is initially quenched due to the suppression of the intramolecular charge transfer (ICT) process and the activation of the photoinduced electron transfer (PET) mechanism. Upon interaction with Cys, a distinct fluorescence emission at 755 nm is observed. The dual-quenching mechanism of <strong>CQAI</strong> offers a high imaging contrast, exceptional selectivity (unaffected by potential interferents such as homocysteine, glutathione, and hydrogen sulfide), and excellent sensitivity, with a detection limit as low as 0.14 μM. Owing to its high cellular permeability and low cytotoxicity, <strong>CQAI</strong> effectively detects both endogenous and exogenous Cys in living cells. Furthermore, it enables the monitoring of Cys levels in tumor-bearing mice, taking advantage of its long-wavelength fluorescence for deep-tissue imaging. The superior performance of <strong>CQAI</strong> highlights its outstanding potential as a powerful tool for exploring the physiological and pathological roles of Cys in complex biological systems.</div></div>","PeriodicalId":302,"journal":{"name":"Dyes and Pigments","volume":"245 ","pages":"Article 113142"},"PeriodicalIF":4.2,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144907132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fluorescent molecular imaging probes for the specific detection of sulfites are hindered by poor solubility, which affects the sensitivity to sulfites and limits the range of applications. Here, we developed an eco-friendly near-infrared fluorescent probe <strong>XQD-H</strong>, by constructing a distinctive “Dual-Positive-Ion” platform to address the above challenges. The typical acceptor-π-acceptor (A−π−A) structure puts <strong>XQD-H</strong> fluorescence in the dark state, and its specific combination with HSO₃⁻ rapidly transforms from the A−π−A type to the donor-π-acceptor (D−π−A) type to achieve significant fluorescence release. Notably, <strong>XQD-H</strong> showed excellent optical properties for HSO₃⁻ in aqueous solution, possessing the advantages of ultra-rapid response, high sensitivity, low detection limits, strong resistance to interference and a wide pH range of applicability. In addition, the detection of HSO₃⁻ by the probe <strong>XQD-H</strong> can also be observed with the naked eye under visible light, offering an easy and intuitive method for detection. The <strong>XQD-H</strong> has been successfully used for rapid quantitative detection of sulfites in food, water samples and cellular mitochondria.
