Abstract

F^- ions (fluoride ions) are crucial in various chemical waste and environmental safety contexts. However, excessive fluoride exposure can pose a threat to human well-being. In this study, a simple 4-substituted pyrene derivative known as 4-hydroxypyrene (4-PyOH) was designed as a colorimetric probe for detecting F^- through the formation of hydrogen bonds between F^- and a hydroxyl group. The probe 4-PyOH exhibited exceptional sensitivity and selectivity towards F^- ions and was successfully utilized as test strips for detecting F^- ions in organic solvents. The detection limit reached an impressively low level of 3.06 × 10^-7 M in the organic solvent. The recognition mechanism was confirmed through ¹H NMR titration.

使用 4-羟基芘探针对四氢呋喃和二甲基亚砜中的氟化物进行比色和荧光测定。

F- 离子（氟离子）在各种化学废物和环境安全方面至关重要。然而，过量接触氟会对人类健康造成威胁。本研究设计了一种简单的 4 取代芘衍生物，即 4-hydroxypyrene (4-PyOH)，通过 F- 与羟基之间形成的氢键作为检测 F- 的比色探针。探针 4-PyOH 对 F- 离子具有极高的灵敏度和选择性，被成功地用作检测有机溶剂中 F- 离子的试纸。在有机溶剂中，其检测限低至令人印象深刻的 3.06 × 10-7 M。通过 1H NMR 滴定法确认了识别机制。
