Four phenanthroimidazole ferrocene derivatives (2a–2d) were designed, synthesized and characterized by ¹H NMR, ¹³C 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 B₄O₇²⁻ selectively among the tested anions with an obvious color change observed. ¹H NMR titrations and theoretical calculations demonstrated that 2b binds B₄O₇²⁻ through O⋯H hydrogen bonding and O⋯B interactions between the nitro moiety and the B₄O₇²⁻ anion.

基于硝基取代的菲咪唑二茂铁衍生物的 B4O72- 阴离子的第一个比色受体†

设计、合成了四种菲咪唑二茂铁衍生物 ( 2a-2d )，并通过¹ H NMR、¹³ C NMR 和高分辨率质谱 (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，表明2b和2d在被测阴离子中选择性地感知B ₄ O ₇^2-，观察到明显的颜色变化。¹ H NMR 滴定和理论计算表明2b结合 B ₄ O ₇^2-_{通过硝基部分与 B 4} O ₇^2-阴离子之间的 O⋯H 氢键和 O⋯B 相互作用。
