Fluorescence Chemosensor for Fluoride Anion with Coumarin Bipyridine Derivative

摘要

On account of the important roles of anion in biological, clinical, environmental, catalysis, and chemical processes, the selective and efficient recognition of anion is an area of growing interest in supramolecular chemistry. In particular, the studies of chemosensors toward fluoride anion are quite intriguing because of its beneficial effects in human physiology.3'4 Also, fluoride is of 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.
