The supramolecular chemistry of anions provides a means to sense and manipulate anions in their many chemical and biological roles. Anions are ubiquitous and they have major roles in the natural world. In particular, the studies of 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, the development of reliable sensors for F- is needed for environment and human health care. Fluorescent chemosensors can be effectively used as a tool to analyze and classify such roles of charged chemical species in living system as well as to measure the amount of ions from the sources contaminated with them. Among anion receptors, colorimetric and fluorescent chemosensors are important because they provide high sensitivity and convenience for monitoring the anion recognition. The salt type derivative was obtained successfully by the reaction of triphenylphosphine with pyrene derivative. The binding properties of triphenylphosphine derivative investigated with 1H-NMR and fluorescence titration methods with various anions.
