摘　　要：设计合成了含氨基蒽醌信号单元的咔唑磺胺类阴离子受体L,通过~1H NMR、^(13)C NMR、MS、IR和元素分析对其结构进行了表征.UV-Vis与荧光光谱滴定实验表明,在二甲基亚砜(DMSO)中L对F-表现出了高选择性识别并与之形成了1∶1型氢键配合物.此外,F-诱导受体L的荧光出现明显猝灭且使受体溶液由红色变为紫红色,表明L可同时作为F-的荧光和比色传感器加以使用.A novel carbazole sulfonamide-based anion receptor（L） containing the aminoanthraquinone signalling units was designed and synthesized, which was characterized by ~1H NMR, ^（13） C NMR, MS, IR and elemental analysis. The obtained results from UV-Vis and fluorescence titrations indicated that receptor L realized a highly selective recognition of F- via the formation of a 1∶1 H-bonding complex. Moreover, the presence of F- induced a significant fluorescent quenching and a color change（from red to purple-red） of dimethyl sulfoxide（DMSO） solution of L, suggesting its potential as fluorescent and colorimetric sensors for the detection of F-.
