We have introduced novel fluoride sensory systems and showed the possibility to amplify the response using the receptor-semiconductor conjugate. To our knowledge, this is the first example to use the fluoride-induced chemical cyclization reactions as fluoride-sensing systems. In addition, while most fluoride sensors known rely on changes in emission intensity, our sensory systems belong to few indicators which utilize new fluorescence signal. As our strategies are based on the specific affinity of fluoride to silicon, they are highly selective for fluoride ion. Indeed, all the indicators developed were stable to an excess of chloride or iodide ion. Other advantages of our sensory systems include the possibility to tune their colors by synthetic manipulation. |
