Consequently, in-situ detection of H₂S in plants is of great significance for studying the physiological mechanisms of H₂S within the plant system. In this study, a highly water-soluble probe with long-wavelength emission for in-situ detection of H₂S in plants was synthesized. The ring-forming structure of phosphorus atom improves its water solubility. By introducing 2,4-dimethoxyphenyl to the boron-dipyrromethene (BODIPY) structure, DPOD-NO₂ possesses a large Stokes Shift (76 nm). Furthermore, the long-wavelength emission at 616 nm reduces the interference from plant self-fluorescence. The nitro group was chosen as the recognition group, and the specific recognition of H₂S was achieved through the intramolecular charge transfer (ICT) mechanism. The DPOD-NO₂ shows excellent linearity within the H₂S concentration range of 0.1 to 90 μM, with a detection limit of 0.063 μM. Importantly, DPOD-NO₂ enabled successfully in situ detection and imaging of H₂S in plants due to its excellent biocompatibility and detection performance. The imaging results reveal the variations in H₂S content within the root systems of wheat seedlings under Al³⁺ stress, drought stress, and flooding stress. Consequently, this work presents a novel probe for further exploring the role and mechanism of H₂S in plants’ responses to environmental stresses.</div></div>","PeriodicalId":16782,"journal":{"name":"Journal of Photochemistry and Photobiology A-chemistry","volume":"466 ","pages":"Article 116409"},"PeriodicalIF":4.1,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143715036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental process involves diazo coupling futibatinib with sodium nitrite to produce a diazonium ion, which then interacts with 1-Naphthol to develop a red-colored chromogen complex.

It is necessary to clarify what kind of intercalation environment promotes the high-order architecture formation suitable for the more efficient photo-induced morphology change. In this study, we have focused on the pH conditions of intercalation solution and analyzed the nanostructure and morphology change of the hybrid fabricated under the basic (pH = 11.0) and the acidic (pH = 2.4) conditions. Intercalating C3F-Azo-C6Hs into the nanosheets under the basic condition afforded a larger interlayer distance as compared with that under the acidic condition.

Under the basic conditions, the nanostructure of the C3F-Azo-C6Hs bilayer having non-interdigitation of the terminal alkyl chain of the two-monolayers faced each other in the bilayer caused the substantial morphology changes such as interlayer distance change and nanosheet sliding, whereas the deeply interdigitated terminal alkyl chains in the hybrid fabricated under the acidic conditions caused only a little/negligible morphology change.
