The recognition of HSO3− by the probe results in a marked color change and a significant enhancement in near-infrared fluorescence, offering high sensitivity (limit of detection = 95.12 nM), rapid response, and minimal interference from environmental background signals. The recognition mechanism involves the specific addition of HSO3− to the 4-position of the quinolinium moiety, triggering an intramolecular charge transfer effect that leads to both colorimetric and fluorescence dual responses. QSB-M was also successfully applied for in situ visualization of HSO3− in various foods and traditional Chinese medicines (TCM), with recoveries ranging from 90 % to 115 %. Additionally, test strips and a smartphone-assisted sensing platform were developed, enabling direct detection of HSO3− levels in foods and TCM without the need for complex instrumentation.

In this study, SnS2 synthesized by three methods, salt melting, hydrothermal synthesis, and solid-state reaction, were investigated, and their morphological and phase composition were studied. The stability of the materials under different light sources and environmental conditions was analyzed by electrochemical measurements, scanning electron microscopy (SEM), X-ray diffraction (XRD), spectroscopy and Raman imaging. The results demonstrate that the photostability of SnS2 pigments is influenced by their composition and morphology, with non-stoichiometric and flower-like structures exhibiting enhanced resistance.

To bridge this gap, we synthesized and studied a series of donor-acceptor-acceptor (D-A-A1) organic dyes incorporating various chalcogenadiazole acceptors (A) and a cyanoacrylic acid acceptor (A1). Using spectroscopic analysis and TD-DFT calculations, we examined changes in electronic and geometric structures induced by subtle modifications in the acceptor units. Our findings reveal that compounds featuring an additional nitrogen atom in the ortho-position adopt a planar geometry in the first excited singlet state, leading to a blue shift in the emission spectrum while maintaining a high luminescence quantum yield of up to 63 % in cyclohexane. The results demonstrate that a planar excited-state geometry enhances ICT emission efficiency compared to a twisted configuration. Additionally, we identified a distinct solvatochromic behavior in the studied dyes. These insights contribute to a deeper understanding of the TICT mechanism and provide a new strategy for designing highly luminescent organic dyes.</div></div>","PeriodicalId":302,"journal":{"name":"Dyes and Pigments","volume":"239 ","pages":"Article 112761"},"PeriodicalIF":4.1,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143679017","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}

Spectroscopic measurements of these complexes in the presence of tetrabutylammonium acetate (TBAAc) as a source of CH3COO− and tetrabutylammonium phosphate (TBAP) as a H2PO4− source were performed. 1H NMR spectra showed that the 1-(fluoranthene-3-yl)-3-phenylurea (3FU) derivatives formed complexes with CH3COO− and H2PO4− in the ground state through hydrogen bonding interactions. Time-resolved fluorescence spectra showed that the maximum fluorescence wavelength of the T∗ species containing CH3COO− did not change with time, whereas that of the T∗ species containing H2PO4− shifted to a longer wavelength. These results indicated that in the excited state, the structure of T∗ with H2PO4− might be different from that of T∗ with CH3COO−.
