设计并合成了一种基于带有 2-吡啶甲酸酯部分的 BODIPY 衍生物的新型比率化学剂量计 1，用于检测缓冲水溶液中的铜离子 (Cu2+)。在所测试的金属离子中，只有在探针1中添加Cu2+才能导致发射带从574 nm红移至593 nm，并在365 nm紫外灯照射下颜色从黄色变为红色。机理研究表明探针1可以通过与Cu2+络合而被高度选择性地水解，生成带有2-吡啶甲酸的BODIPY衍生物。计算检测限为0.08 μM。此外，探针1可用于检测实际水样和滤纸上的Cu2+。
A novel ratiometric chemodosimeter 1 based on a BODIPY derivative bearing a 2-picolinic ester moiety has been designed and synthesized for copper ion (Cu2+) detection in aqueous buffered solution. Among the tested metal ions, only the addition of Cu2+ to probe 1 could lead to a red shift of the emission band from 574 nm to 593 nm, accompanied by a color change from yellow to red under illumination with a 365 nm UV lamp. Mechanism research suggested that probe 1 could be highly selectively hydrolyzed by complexation with Cu2+ to generate a BODIPY derivative bearing 2-picolinic acid. The detection limit was calculated to be 0.08 μM. Moreover, probe 1 could be used to detect Cu2+ in real water samples and on filter paper.
