Abstract

The invention provides a methylquinolin-benzopyranium derivative and a preparation method and application thereof. The preparation method of the methylquinolin-benzopyranium derivative is simple, rawmaterials are cheap and easy to obtain, the synthesis cost is low, the methylquinolin-benzopyranium derivative shows the advantages of high selectivity, low detection limit, large Stokes shift and ultra-sensitive responsiveness to SO2 detection, and CMQ has good water solubility and can realize efficient detection of SO2 in a water phase system. Meanwhile, the CMQ has good biocompatibility, has agood fluorescence development effect in living cells, and can be used for detecting SO2 in the cells. The methylquinolin-benzopyranium derivative can also realize quantitative detection of SO2 additives in foods, can also be prepared into an SO2 detection kit, is convenient for determination of the content of SO2 additives in various foods, and has a wide market application prospect.

Description

technical field

[0001] The invention belongs to the field of chemical synthesis and biosensing technology, and specifically relates to a methylquinoline-benzopyrylium derivative and a preparation method thereof, and also relates to the methylquinoline-benzopyrylium derivative It is used in the detection of sulfur dioxide in aqueous phase systems, food and living cell mitochondria. Background technique

[0002] For a long time, sulfur dioxide (SO 2 ) is considered to be a toxic environmental pollutant, when the human body is acutely or chronically exposed to SO 2 increased risk of respiratory and cardiovascular disease, lung cancer, and many neurological disorders. At the same time, HSO 3 − / SO 3 2− It has good antibacterial, antibacterial and antioxidative properties, so it has been widely used as a preservative in food, wine and pharmaceutical processing industries. However, HSO 3 − / SO 3 2− Excessive ingestion of large amounts can cause asthma and other allergic ...
