摘要

研制了一种新型萘酰亚胺化学传感器(R)，通过F驱动脱硅-脱氰级联检测氟。该探针在紫外可见吸收方面表现出明显的“肉眼”变化（红移300 nm），并且对氟化物（LOD = 27.2 nm）具有荧光关闭响应。通过光谱比较、核磁共振滴定和质谱分析证实了其传感机理。据此，制备了载r试纸，用于检测水溶液中的氟化物。

A fluoride-responsive naphthalimide-derived chemosensor: Mechanistic insights into F--driven desilylation-decyanation cascade

A new naphthalimide-derived chemosensor (R) was developed for the detection of fluoride through F^--driven desilylation-decyanation cascade. The probe exhibited significant "naked-eye" changes in UV–visible absorption (red shift of 300 nm), and a fluorescent turn-off response to fluoride (LOD = 27.2 nM). The sensing mechanism was confirmed by spectral comparison, NMR titration, and MS analysis. Accordingly, R-loaded test paper was prepared and used to detect fluoride in aqueous solutions.

期刊介绍： The Journal of Fluorine Chemistry contains reviews, original papers and short communications. The journal covers all aspects of pure and applied research on the chemistry as well as on the applications of fluorine, and of compounds or materials where fluorine exercises significant effects. This can include all chemistry research areas (inorganic, organic, organometallic, macromolecular and physical chemistry) but also includes papers on biological/biochemical related aspects of Fluorine chemistry as well as medicinal, agrochemical and pharmacological research. The Journal of Fluorine Chemistry also publishes environmental and industrial papers dealing with aspects of Fluorine chemistry on energy and material sciences. Preparative and physico-chemical investigations as well as theoretical, structural and mechanistic aspects are covered. The Journal, however, does not accept work of purely routine nature. For reviews and special issues on particular topics of fluorine chemistry or from selected symposia, please contact the Regional Editors for further details.
