摘　　要：制备了一种基于久洛尼定的新型比色化学传感器JB-2OH,并通过紫外-可见吸收光谱研究了其对阴离子的识别。研究表明:氟离子的加入会使JB-2OH乙腈溶液的吸收光谱和溶液颜色发生变化,而其它阴离子(Cl^-,Br^-,I^-,ClO_4^-,HSO_4^-,NO_3^-,AcO^-,H_2PO_4^-,)的加入不会产生明显的影响。JB-2OH可作为一种高选择性比色化学传感器用于氟离子的检测。A new chemsensor JB-2OH was prepared based on julolidine, and the recognition between JB-2OH and anion ions were studied by UV - Vis spectra. The results indicated that the spectra and solution color of JB-2OH were changed while the fluoride ion was added. The present of some other anion ions including Cl-, Br- ,I-, CIO4 - , HSO4 -, NO3 - ,AcO-, H2PO4 - , almost have no influences. It is thus clear that JB-20H waa a promising colorimetrie chemosensor for fluoride ion by naked - eye recognition with excellent selectivity.
