摘要: 设计合成了一个反应型的硼氟二吡咯(BODIPY)类荧光探针1,该探针以吡啶-2-羧酸苯酚酯基为识别基团。通过1H NMR、13C NMR和HRMS表征了1的结构,并解析了其晶体结构。光谱分析实验结果显示,探针1具有高的荧光量子产率(0.79),对Cu2+具有较强的选择性识别性能,并能成功应用到生物细胞中Cu2+的成像检测。 |

Abstract: A fluorescent probe 1, based on boron fluoride dipyrrole (BODIPY) chromophore containing phenyl picolinate as a recognition moiety, was designed, synthesized, and characterized by 1H NMR, 13C NMR, HRMS and X-ray diffraction. Probe 1 had a high fluorescence quantum yield (0.79), and could selectively and sensitively recognize Cu2+ from other cations by a fluorescence quenching method. The limit of detection of probe 1 was 0.15 μmol·L-1. In addition, the recognition mechanism of the fluorescent response to copper ions was verified by HRMS in this work. |
Keywords: boron fluoride dipyrromethene copper ion fluorescent probe fluorescence quenching |
