提高荧光探针的光稳定性是提高其性能的关键。发现了一种独特的聚硅氧烷基咪唑离子液体（PSI），可以提高荧光探针的光稳定性。本研究首次以1,3-双（3-氨基丙基）四甲基二硅氧烷和醛为原料，通过聚radziszewski反应，合理设计合成了一种新型聚硅氧烷基咪唑衍生物（PSI）。然后用硫代萘酸酐（NA）功能化psi，制备基于离子液体的荧光探针psi -NA，用于检测SCN−。这是构建多离子基荧光探针的首次报道。与小分子探针相比，psi - na具有较高的稳定性，在生物成像和纸基传感器等领域得到了进一步的应用。为提高荧光探针的光稳定性提供了一种有效的方法。
Enhancing of the photostability of the fluorescent probes is a crucial task for promoting the performances. A unique polysiloxane-based imidazolium ionic liquid (PSI) was found to improve the photostability of the fluorescent probe. In this study, we reported the rational design and synthesis of a novel kind of polysiloxane-based imidazolium derivative (PSI) prepared from 1,3-bis(3-aminopropyl)tetramethyldisiloxane and aldehyde through the poly-radziszewski reaction for the first time.PSIwas then functionalized by thionaphthalic anhydride (NA) to fabricate ionic liquid based fluorescent probePSI-NAfor the detection of SCN−. This work represented the first report for the construction of poly-ionic based fluorescent probes. Compared with small molecule probe,PSI-NAexhibited high stability and further applied in bioimaging and paper-based sensor fields. This work presented a valid approach for enhancing the photostability of fluorescent probes.
