The studies of chemosensors toward F- anion are quite intriguing because of its beneficial effects in human physiology. Also, fluoride is interest due to its established role in dental care and osteoporosis. However, an excess of fluoride ion can lead to fluorosis. Therefore, developments of reliable sensors for fluoride ion are needed for environment and human health care. Among anion receptors, colorimetric and fluorescent chemosensors are important because they provide high sensitivity and convenience for monitoring the anion recognition.1 Especially, coumarine are a particularly elegant basis for ratiometric based optical sensors. Here, we report a novel coumarine bipyridine chemosensor 1 with a specific optical response to fluoride ion. In pursuit of a selective fluoride chemosensor, a coumarine bipyridine derivative 1 was synthesized, and its anion binding properties were investigated by 1H NMR, UV-vis spectroscopy, color changes, and fluorescence titration analysis.
