设计并合成了一种基于BODIPY-半花菁的新型氰化物荧光探针1。在测试的阴离子中，探针对CN−表现出高选择性。在水溶液（VH 2 O/VEtOH= 1/1）中，仅加入CN-，探针1的吸收峰从385 nm蓝移到265 nm，荧光增强20倍。通过1H NMR和质谱分析证实了该传感器的传感机理是基于CN-与吲哚基团之间的亲核加成反应。在0-10 μM范围内，荧光强度与CN−浓度呈良好的线性关系，检测限为1.53 ppb。此外，所提出的传感方法可以在5.0-9.0的宽pH范围内工作，并瞬间达到平衡。最后，将探针1成功应用于天然水样和试纸条中CN-的检测，结果令人满意。
A novel BODIPY-hemicyanine based fluorescent probe1for cyanide (CN−) detection was designed and synthesized. Among the tested anions, the probe showed high selectivity towards CN−. Only addition of CN−to probe1in aqueous solution (VH2O/VEtOH= 1/1) could result in a remarkable blue shift of the absorption band from 385 nm to 265 nm and induce 20-fold fluorescence enhancement at 515 nm. The sensing mechanism was based on nucleophilic addition between CN−and indolium group, which was confirmed by1H NMR and mass spectrum analysis. Plot of fluorescence intensity as a function of CN−concentrations exhibited a good linear relationship in the range of 0–10 μM, with a detection limit to be 1.53 ppb. Moreover, the proposed sensing approach could work in a wide pH range from 5.0–9.0 and reach an equilibrium instantaneously. Finally, probe1was successfully applied in detection of CN−in natural water samples and on test paper strips with satisfactory results.
