In this paper, anion probe 1 was designed and synthesized by using phenprocoumon containing acyl hydrazine with p-nitro azo salicylaldehyde reaction Dickson et al. (2008) Dickson et al. (2008) [1]. In the anion probe 1, the nitro moiety is a signaling group and the phenolic hydroxyl moiety is anion binding site. Then the anion probe 1 was characterized by mass spectra (MS) and infrared spectra (IR). The binding properties of the anion probe 1 for anions such as F(-), AcO(-), H2PO4(-), OH(-), Cl(-), Br(-) and I(-) were investigated by ultraviolet-visible (UV-Vis) spectra and fluorescence spectra Shao et al. (2008) Shao et al. (2008) [2]. Furthermore, the color of anion probe 1 after addition of F(-), AcO(-), H2PO4(-) and OH(-) in DMSO changed from yellow to blue, while no obvious color changes were observed by addition of other tested anions. Accordingly, the anion probe 1 could sense visually F(-), AcO(-), H2PO4(-) and OH(-) without resorting to any spectroscopic instrumentation Amendola et al. (2010) Amendola et al. (2010) [3].
在本文中，阴离子探针1是通过使用含酰肼的苯丙香豆素与对硝基偶氮水杨醛反应设计合成的（迪克森等人，2008年；迪克森等人，2008年[1]）。在阴离子探针1中，硝基部分是信号基团，酚羟基部分是阴离子结合位点。然后，通过质谱（MS）和红外光谱（IR）对阴离子探针1进行了表征。通过紫外可见（UV-Vis）光谱和荧光光谱研究了阴离子探针1对F(-)、AcO(-)、H2PO4(-)、OH(-)、Cl(-)、Br(-)和I(-)等阴离子的结合特性（邵等人，2008年；邵等人，2008年[2]）。此外，在二甲基亚砜（DMSO）中加入F(-)、AcO(-)、H2PO4(-)和OH(-)后，阴离子探针1的颜色从黄色变为蓝色，而加入其他测试阴离子时未观察到明显的颜色变化。因此，阴离子探针1无需借助任何光谱仪器即可直观地检测F(-)、AcO(-)、H2PO4(-)和OH(-)（阿门多拉等人，2010年；阿门多拉等人，2010年[3]）。
