Four phenanthroimidazole ferrocene derivatives (2a-2d) were designed, synthesized and characterized by H NMR, C NMR and high-resolution mass spectroscopy (HRMS). Recognition of 12 anions by 2a-2d was investigated by UV-Vis absorption analysis, showing that 2b and 2d sensed BO selectively among the tested anions with an obvious color change observed. H NMR titrations and theoretical calculations demonstrated that 2b binds BO through O⋯H hydrogen bonding and O⋯B interactions between the nitro moiety and the BO anion.
设计、合成了四种菲并咪唑二茂铁衍生物（2a - 2d），并通过氢核磁共振（¹H NMR）、碳核磁共振（¹³C NMR）和高分辨质谱（HRMS）对其进行了表征。通过紫外 - 可见吸收分析研究了2a - 2d对12种阴离子的识别情况，结果表明，在测试的阴离子中，2b和2d对硼酸根（BO₃³⁻）具有选择性传感作用，观察到明显的颜色变化。¹H NMR滴定和理论计算表明，2b通过硝基部分与硼酸根阴离子之间的O⋯H氢键和O⋯B相互作用与硼酸根（BO₃³⁻）结合。
