【摘要】：报道了一种基于香豆素衍生物与铜离子的络合物(C1-Cu),可通过间接的方法检测硫离子。络合物C1-Cu的溶液中加入硫离子后,表现出明显的荧光增强响应,检测灵敏度高,检出限低达90 nmol/L;响应速度快,可实现硫离子的实时检测;荧光强度变化与硫离子浓度呈现良好的线性关系,能准确地定量分析硫离子浓度。上述络合物C1-Cu对硫离子的检测具有超高的选择性,即使在其他阴离子存在下也能高效地识别出硫离子;得益于香豆素良好的水溶性和生物相容性,上述络合物C1-Cu可实现生物细胞中硫离子的荧光成像。除荧光光谱响应之外,该体系对硫离子亦有紫外-可见光谱响应,无需借助任何仪器便可实现对硫离子方便、快捷的"裸眼"检测。
[Abstract]:A complex (C1-Cu) based on coumarin derivatives and copper ions is reported, which can be used to detect sulfur ions indirectly. When sulfur ions are added into the solution of complex C1-Cu, the fluorescence enhancement response is obvious, the detection sensitivity is high, the detection limit is up to 90 nmol/L; and the response speed is fast, so the real-time detection of sulfur ions can be realized. The change of fluorescence intensity has a good linear relationship with the concentration of sulfur ion, and it can be used to analyze the concentration of sulfur ion accurately. The complex C1-Cu has high selectivity for the detection of sulfur ions, and can efficiently identify sulfur ions even in the presence of other anions. Thanks to the good water-solubility and biocompatibility of coumarin, the complex C1-Cu can realize fluorescence imaging of sulfur ions in biological cells. In addition to the fluorescence spectral response, the system also has UV-Vis spectral response to sulfur ions. It can be easily and quickly "naked eye" detection of sulfur ions without any instrument.
