| titleOfInvention | Fluorescent probe, preparation method thereof and application thereof in iron ion detection |
| abstract | The invention provides a fluorescent probe and a preparation method thereofThe method and the application in the iron ion detection belong to the technical field of fluorescence sensing. In the fluorescent probe provided by the invention, a rigid main chain M provides an active site for complexing of iron ions, and the periphery of the main chain and R 1 The groups are connected, so that the solubility of the fluorescent probe is improved, the fluorescent probe is easily dissolved in a solvent to form a uniform solution, and further the detection of iron ions is realized; and R 3 And R 2 The existence of the group can further improve the conjugation degree of the fluorescent probe, thereby improving the fluorescence efficiency of the fluorescent probe. When the fluorescent probe provided by the invention is used for detecting iron ions, the linear relation is better in the range of 1-10 mu M, the fluorescence quenching rate of the fluorescent probe to an iron ion solution is as high as 84%, and the detection limit is as low as 33nM, which shows that the fluorescent probe provided by the invention has high sensitivity, good selectivity and low detection limit to the iron ions. |
