Abstract	새로운 불소 이온 감지용 화학 센서를 합성하였다. 탈실리콘화 과정에서 만들어지는 페녹사이드를 친핵체로 사용하여 형광 물질로 락톤화되는 기존의 방법에 대한 추가적인 설명과 함께 탈실리콘화에 의한 방향족 화합물의 평면 화를 통한 형광의 변화 방법이 새로이 제시되었다. 개발된 센서들은 불소에 대해 선택적인 친화력을 갖는 실리콘을 이 용하므로 불소 이온에 대해 높은 선택성을 보였다. 또한, 합성된 센서에 공액 고분자를 연결하여 그 감도를 성공적으로 증대시켰다. Novel fluoride sensory systems have been successfully developed. Previously developed method of the fluoride-induced lactonization to fluorescent molecules was detailed, and newly developed fluoride-induced aromatic cyclization scheme was introduced. Based on the strategies using the specific affinity of fluoride to silicon, our systems are highly selective for fluoride ion. Incorporation of the developed sensor to a conjugated polymer has successfully enhanced its sensitivity to fluoride ion.
