Two sensitive and ratiometric fluorescent probes (probe I and probe II) were developed for the detection of fluoride ions. Probe I can detect fluoride ions quantitatively within a range of 0-6 μM and a detection limit of 73 nM, while probe II has a range of 0-40 μM and a detection limit of 138 nM. The test strips from probe I are quickly able to recognize F (5 min) inside of the F safety level in drinking water (1.0 mg/L, ∼5 μM) under 254 nm ultraviolet light, and the test strips from probe II quickly recognize F (12 min) in dangerously high F levels in water (4.0 mg/L, ∼21 μM) under 254 nm ultraviolet light. This combination of fluorescent paper sensors from probe I and probe II can be used as a simple and convenient tool to determine whether water is safe to drink or dangerous.
开发了两种用于检测氟离子的灵敏且具有比率荧光的探针（探针I和探针II）。探针I能够在0 - 6 μM范围内定量检测氟离子，检测限为73 nM，而探针II的检测范围为0 - 40 μM，检测限为138 nM。来自探针I的测试条能够在254 nm紫外光下快速识别饮用水中氟安全水平（1.0 mg/L，约5 μM）内的氟（5分钟），来自探针II的测试条能在254 nm紫外光下快速识别水中高危险氟水平（4.0 mg/L，约21 μM）中的氟（12分钟）。这种由探针I和探针II组成的荧光纸传感器组合可作为一种简单便捷的工具来确定水是否可安全饮用或是否危险。
