Currently, there is a great need to develop methods for the selective detection of fluoride anions (F(-) ) owing to their toxicity in the environment and biological function in living systems. In this study, we developed a new fluorescent probe (probe 1) employing a Si-O bond as a highly selective recognition receptor for detecting F(-) via intramolecular charge transfer. Probe 1 could detect F(-) quantitatively using the turn-on fluorescence spectroscopy method with excellent sensitivity in the range of 4-38 μM and a detection limit of 0.26 μM; the detection time was < 17 min. We anticipate that probe 1 would be used widely to monitor F(-) in the environment. Copyright © 2015 John Wiley & Sons, Ltd.
目前，由于氟离子（F(-)）在环境中的毒性及其在生物系统中的生物学功能，开发选择性检测氟离子的方法具有迫切需求。在本研究中，我们开发了一种新型荧光探针（探针1），该探针利用Si-O键作为高选择性识别受体，通过分子内电荷转移来检测F(-)。探针1可采用荧光开启光谱法对F(-)进行定量检测，在4 - 38 μM范围内具有出色的灵敏度，检测限为0.26 μM；检测时间小于17分钟。我们预计探针1将被广泛用于监测环境中的F(-)。版权所有© 2015约翰威立父子有限公司。
