A simple, highly selective and sensitive chemosensor (E)-2-((quinolin-8-ylimino) methyl) phenol (QP) has been developed for the fluoride, as demonstrated by the photophysical properties obtained by UV-vis and fluorescent methods. Excited-state inter/intramolecular proton transfer (ESPT) was suggested to be responsible for the fluoride-induced 'turn on' fluorescence and the blue shift of 25 nm in the emission spectrum.
已开发出一种简单、高选择性且灵敏的化学传感器（E）-2-（（喹啉-8-基亚氨基）甲基）苯酚（QP）用于检测氟化物，紫外可见光谱和荧光法获得的光物理性质证明了这一点。激发态分子间/分子内质子转移（ESPT）被认为是氟化物诱导的“开启”荧光以及发射光谱中25nm蓝移的原因。
