摘　　要：设计合成了一种基于久洛尼定的苯腙型化学传感器C1,应用紫外-可见吸收光谱研究了该传感器分子与阴离子的相互作用。结果表明:传感器分子C1在乙腈中可以选择性地识别氟离子,氟离子加入可使吸收光谱发生50 nm红移,溶液颜色由黄色变为紫色;其他阴离子Cl^-,Br^-,I^-,ClO_4^-,HSO_4^-,NO_3^-,AcO^-和H_2PO_4^-的加入不会对吸收光谱产生明显的影响,可见所设计的传感器分子C1可作为高选择性裸眼识别氟离子的比色传感试剂。A new chemosensor（ C1） was designed and synthesized based on julolidine. The interaction between C1 and anion ions was investigated by UV-Vis spectra.The results indicated that the fluoride ion can be recognized selectively in the solution of C1 in acetonitrile.Upon addition of fluoride ion,the absorption spectrum red-shifted by 50 nm,and a significant color change from yellow to purple was observed. The other anion ions,including Cl^-,Br^-,I^-,ClO4^-,HSO4^-,NO3^-,AcO^-,H2PO4^-,almost have no influences.It is thus clear that the C1 was a promising colorimetric chemosensor for fluoride ion by naked-eye recognition with excellent selectivity.
