Development of Highly Selective Fluorescent Chemosensors for Fluoride Ion

Novel fluoride sensory systems were successfully developed. Previously developed method of the fluoride-induced lactonization to fluorescent mols. was detailed, and newly developed fluoride-induced arom. cyclization scheme was introduced. Based on the strategies using the specific affinity of fluoride to silicon, the authors’ systems are highly selective for fluoride ion. Incorporation of the developed sensor to a conjugated polymer has successfully enhanced its sensitivity to fluoride ion. [on SciFinder(R)]
