1,4-Dihydropyridines are a class of drugs with a wide range of biological activities and pharmacological effects. However, there are few reports on its optical activity, especially its application on fluorescent CN- probe. In this experiment, we designed and synthesized a fluorescent probe based on 1,4-dihydropyridines to detect CN-. Interestingly, the probe exhibited outstanding properties such as 100% water soluble, near infrared, ratiometric, fast response, high selectivity and anti-interference ability for other ions. The color change indicated that the probe can be used for naked eye identification. In particular, the probe showed a super large fluorescent emission peak shift (260 nm). In addition, the reaction mechanism of the probe has been studied by 1H NMR titration, high resolution mass spectrometry and theoretical calculations.

基于1,4-二氢吡啶类化合物的新型100%水溶液近红外比率荧光CN-探针,具有大的荧光发射峰位移

1,4-二氢吡啶类是一类具有广泛的生物活性和药理作用的药物。不过,也有它的光学活性,特别是其对荧光CN应用鲜有报道-探头。在这个实验中,我们设计并合成了基于1,4-二氢吡啶来检测CN荧光探针- 。有趣的是,该探针表现出出色的性能,例如100%水溶性,近红外,比例测定,快速响应,高选择性和对其他离子的抗干扰能力。颜色变化表明该探头可用于肉眼识别。特别地,该探针显示出超大的荧光发射峰位移(260nm)。另外,对探针的反应机理进行了研究11 H NMR滴定,高分辨率质谱和理论计算。
