Abstract

The invention relates to a turn-on type fluorescent probe for rapidly detecting sulfite(bisulfite). The molecular formula of the fluorescent probe is C21 + nH15 + mN1 + xO3 + y, wherein n, m, x and yare all integers from 1 to 20, and the molecule has the following structure: substituent R1 is one of H, alkyl, aryl, nitryl, ester group, ether group and diethylamino, and n in the 3-indolecarboxaldehyde derivative is an integer from 1 to 20. The fluorescent probe is short in response time(10 seconds), high in measurement sensitivity, simple in molecular structure and simple and convenient in synthesis method, and can be used for cell imaging and detection of sulfite(bisulfite)in food and traditional Chinese medicinal materials, so that the fluorescent probe is extremely easy to popularize and apply practically.

Description

technical field [0001] The invention belongs to the technical field of chemical analysis and detection, in particular to a turn-on type fluorescent probe for rapid detection of sulfite (hydrogen) salt, a synthesis method and an application. Background technique [0002] Sulfur dioxide (SO 2 ) has long been recognized as an environmental pollutant harmful to humans and is the main cause of "acid rain" worldwide. Its main sources are volcanic eruptions and burning of sulfur-based fossil fuels. SO 2 After inhalation into the human body, mainly SO 2 Derivatives - exist in the form of sulfite (hydrogen) salt. Sulfite (hydrogen) salt can also be used as a food additive, but excessive intake will lead to adverse reactions such as hypotension, diarrhea, urticaria, etc. Toxicology and epidemiological studies have proved that the abnormal concentration of endogenous sulfite (hydrogen) is closely related to various diseases, such as respiratory system diseases, nervous system dise...
