A new rhodol-derived fluorescent probe 1 with picolinate as the recognition receptor was designed and simply synthesized using a one-step reaction. With the concentration of added Cu2+ increases, it gradually turns pink, so the effect of naked eye detection can be achieved. The detection limit of probe 1 for Cu2+ is 42 nM, and the linear detection range was 0–2 μM. The experimental results showed that 1 was a fluorescent probe with high selectivity, good water solubility, and high sensitivity to Cu2+.

Rhodol 衍生的具有高选择性和灵敏度的铜离子开启荧光探针

设计并使用一步反应简单地合成了一种以吡啶甲酸酯为识别受体的新型酚醛衍生荧光探针1。随着添加的Cu 2+浓度的增加,逐渐变成粉红色,可以达到肉眼检测的效果。探针1对 Cu 2+的检测限为 42 nM,线性检测范围为 0–2 μM。实验结果表明,1是一种选择性高、水溶性好、对Cu 2+灵敏度高的荧光探针。
