Fluorescent sensing film for pH planar optode, preparation method and application |
| abstract |
The present invention provides a fluorescent dye HPTS-lipo for monitoring two-dimensional pH value, a fluorescent sensing film, and use thereof, belonging to the field of two-dimensional pH value monitoring. The fluorescence sensing film for monitoring two-dimensional pH is prepared from the fluorescent dye HPTS-lipo, and HPTS-lipo is embedded by hydrogel D4 in a preparation process. The fluorescent dye HPTS-lipo is prepared by ligating alkylamine into sulfonic acid groups of the fluorescent dye HPTS. Compared with the fluorescent dye HPTS, the pKa value of the modified fluorescent dye HPTS-lipo is significantly varied, so that the fluorescent sensing film is suitable for monitoring different pH values and meets different experimental requirements; and the fluorescent dye HPTS-lipo has better hydrophobicity, can be kept for longer time in environment, and further solves the problem of dye leakage after being embedded by the hydrogel. |
