The invention relates to a turn-on type fluorescent probe for rapidly detecting (hydrogen) sulfite, the molecular formula of the fluorescent probe is: C 21+n H 15+m N 1+x O 3+y , wherein n , m, x, y are all integers from 1‑20, and the molecule has the following structure: Wherein the substituent R is one of H, alkyl, aryl, nitro, ester, ether and diethylamino, and n in the 3-indolecarboxaldehyde derivative is an integer of 1-20. The fluorescent probe of the present invention has short response time (10 seconds), high determination sensitivity, simple molecular structure, and convenient synthesis method, and can be used for cell imaging and detection of sulfite (hydrogen) in food and Chinese medicinal materials, making it very easy to be popularized and applied in practice . |
