摘　　要：设计合成了一种阴离子受体分子1,4-(4-硝基苯基)-1-(3-氧代-3,4-二氢喹喔啉)氨基硫脲。通过UVVis和荧光光谱考察了其与AcO^-,H_2PO_4-,F^-,Cl^-,Br^-和I^-之间的相互作用。当加入F^-时主体溶液由淡黄色变为蓝色,而当加入AcO-和H_2PO_4^-的时主体溶液由淡黄色变为紫色,而Cl^-、Br^-和I^-的加入主体溶液基本没有变化,可以实现对阴离子的裸眼识别。A simple colorimetric anion sensor 1,was rationally designed and synthesized.The binding properties of the receptor with anions such as AcO^-,H2PO4^-,F^-,Cl^-,Br^- and I^- were investigated by UV-Vis and fluorescent titrations.Upon addition of F^-,the receptor 1 exhibited a red shift in UV-vis spectrum,accompanied by visible color changes from light yellow to blue,Upon addition of AcO^-,H2PO4-,accompanied by visible color changes from light yellow to purple.However,no obvious color changes were observed on addition of Cl^-,Br^- and I^-.Which can be detected by the＂naked-eye＂.
