In this paper, a new kind of phenol-based chemsensor L2 comprised of a Schiff base and azo groups was rationally designed and synthesized. It could selectively recognize fluoride anion among tested anions such as F(-), AcO(-), H2PO4(-), Cl(-), Br(-), and I(-) with obvious color changes from yellow to fuchsia. The intramolecular PT (proton transfer) in L1 and L2 was responsible for the sensing ability, which was certified by the (1)H NMR and Uv-vis experiments.
在本文中，设计并合成了一种新型的基于酚的席夫碱型化学传感器 L2，其由一个席夫碱和偶氮基团组成。L2 可以选择性地识别 F(-)、AcO(-)、H2PO4(-)、Cl(-)、Br(-) 和 I(-)等阴离子中的氟离子，具有明显的颜色变化，从黄色变为品红色。L1 和 L2 中的分子内 PT（质子转移）是其传感能力的原因，这一点通过 (1)H NMR 和 Uv-vis 实验得到了证明。
