| 摘要: 合成和表征了一个苯并噻唑类的荧光探针N-(4-(苯并噻唑-2-基)苯基)-2-((2-羟乙基)(吡啶-2-甲基)氨基)乙酰胺 (FL), 用光谱法研究了它与各种金属离子的识别特性。结果表明：FL对Cu2+具有较高的选择性和灵敏度, 并且对Cu2+的识别不受其它金属离子的干扰。FL与Cu2+形成配合物的结合比为1:1, 其荧光强度与Cu2+浓度(3.8~9.6 μmol·L-1)呈现较好的线性关系, 而且它还可应用于自来水和湖水等水体样品中Cu2+的检测。 |

| Abstract: A benzothiazole-based fluorescent probe N-(4-(benzo[d]thiazol-2-yl)phenyl)-2-((2-hydroxyethyl) (pyridin-2-ylmethyl)amino)acetamide (FL) has been synthesized and characterized, and its recognition properties towards various metal ions have been studied by spectrometry. The results showed that FL was highly sensitive and selective to Cu2+, and other metal ions did not interfere with its recognition for Cu2+. The stoichiometry of the complex formation of FL with Cu2+ was determined to be 1:1, and the fluorescence intensity of FL varied almost linearly versus the concentration of Cu2+ (3.8~9.6 μmol·L-1). FL can also be applied to detect Cu2+ in different water samples such as tap and lake water. |
