Fluoride ion is a strong Lewis base and one of the essential trace elements in human body. It plays a very important role in human health and ecological balance. The deficiency or excessive intake of fluoride ions will cause serious health problems, so the development of a sensitive and accurate detection method for fluoride ions is very important. The colorimetric and/or fluorescence sensing method has been a long standing attractive technique with high sensitivity and fast response. To date, most reported probes for fluoride ion are applicable only in organic solvents or organic-containing aqueous solutions. However, the probes for fluoride ion used in aqueous solution are more practically needed in view of environment protection and human health. In this paper, the materials and designing ideas of the colorimetric and/or fluorescent probes for fluoride ion based on different detection mechanisms in recent years were reviewed. Two main categories including formation of hydrogen bonds and formation of coordination covalent bonds were discussed. The latter one is further subdivided into three types, formation of B-F bond, formation of Si-F bond and formation of M-F bond.
氟离子是一种强路易斯碱，也是人体必需的微量元素之一。它在人体健康和生态平衡中起着非常重要的作用。氟离子缺乏或摄入过量都会导致严重的健康问题，因此开发一种灵敏、准确的氟离子检测方法非常重要。比色和/或荧光传感方法一直是一种具有高灵敏度和快速响应的有吸引力的技术。迄今为止，大多数报道的氟离子探针仅适用于有机溶剂或含有机物的水溶液。然而，考虑到环境保护和人类健康，水溶液中使用的氟离子探针更具实际需求。本文综述了近年来基于不同检测机制的氟离子比色和/或荧光探针的材料及设计思路。讨论了包括氢键形成和配位共价键形成在内的两大类。后者进一步细分为三种类型，即B-F键形成、Si-F键形成和M-F键形成。
