| titleOfInvention | Ratio type fluorescent probe for detecting pH, and preparation method and application thereof |
| abstract | The invention discloses a ratio-type fluorescent probe for detecting pH, a preparation method and application thereof, wherein the structural formula of the ratio-type fluorescent probe is as follows: the preparation method of the fluorescent probe is simple, the product yield is high, and the fluorescent probe is suitable for large-scale popularization and application. The fluorescence of the fluorescent probe under a neutral condition is weak, the solution obtained after the fluorescent probe is added into water or an organic solvent is light yellow, when the acid strength of the solution is increased, the color of the solution is gradually faded and becomes blue-green, the fluorescence is enhanced, the fluorescent probe can detect the range of pH 2-7, and when the pH value is 2-4, the fluorescent probe has a good linear ratio relationship, the background influence can be effectively eliminated, and the detection sensitivity and accuracy are improved. |
