In parallel, the open circuit voltage (<em>V</em>_OC) of the non-fullerene-based organic solar cells (NFAs–OSCs) from the blends of the polymers paired with Y6 were increased from 0.860 V to ∼0.876 V−0.874 V, and then up to 0.892 V, alongside the decrease of the short current density (<em>J</em>_SC) from 27.61 mA/cm² to 20.59 mA/cm², fill factors (<em>FF</em>) from 76.29 % to 53.11 %.

Aqueous [¹⁸F]F⁻ was trapped on cationic quaternary methylammonium (QMA) anion exchange sorbent with carbonate anion and extracted using non-basic chloride or triflate. Evaporative concentration of the eluates at 110 °C resulted in a negligible loss of radioactivity due to [¹⁸F]HF generation [80–98 % decay-corrected (DC) retention in activity], despite the absence of the basic carbonate or bicarbonate anions that are canonically used to strip [¹⁸F]F⁻ from QMA resins. Treatment of the two model BODIPY dyes in either CH₂Cl₂ or CH₃CN afforded their ¹⁸F-labelled analogues in DC radiochemical yields of 47–60 % after solid-phase extraction (SPE) purification. In addition, [¹⁸F]F⁻ elution from anion exchange sorbent and Lewis acid activation were consolidated by employing In(OTf)₃ for both steps, albeit at a cost of increased loss of [¹⁸F]HF during the azeotropic evaporation process (3 portions of CH₃CN; 60 ± 8 % DC retention after dry-down). Finally, [¹⁸F]BODIPY synthesis could be achieved by simply concentrating the ¹⁹F dyes in CH₃CN–H₂O mixtures of In(OTf)₃-eluted [¹⁸F]F⁻, followed by resolubilization in CH₃CN and finally C₁₈ SPE purification. This constitutes a rapid and ultra-simple ¹⁸F-labelling protocol that is amendable to automated synthesis (27–39 % DC radiochemical yields, 50–73 min total synthesis time).

Herein, we report the fabrication of hydrophobic-hygroscopic, pH indicator-based chromic fabric coatings with humidity tolerance for rapid colorimetric NH₃ sensing. The fabric coatings were fabricated by grafting a polymerizable pH indicator (cresol red), hygroscopic monomer, and hydrophobic monomer onto cotton fabrics. The resulting fabrics exhibited opposing hygroscopicity and hydrophobicity. Hydrophobicity, reflected by high water contact angles up to 139.4°, prevented color change induced by various aqueous solutions, and hygroscopicity, with moisture absorption capacity up to 11.3 %, did not have an influence on color change, with color preserved in all relative humidity ranges. After moisture absorption, the fabrics possessed a remarkable color change from yellow to purple upon exposure to alkaline gases (such as NH₃), and the color change could be realized within 5 s. The color change was reversible, and a reusability over 10 cycles was confirmed without obvious deterioration in color change. The simple fabrication, hydrophobicity-hygroscopicity, and rapid response to NH₃ via visual color change make the fabrics an excellent candidate for rapid NH₃ sensing and food spoilage monitoring via changes in color.</div></div>","PeriodicalId":302,"journal":{"name":"Dyes and Pigments","volume":"242 ","pages":"Article 112987"},"PeriodicalIF":4.1,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144471695","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}
