Abstract

The invention discloses a water-soluble supramolecular fluorescent probe and its preparation and application. The molecular formula of the water-soluble supramolecular fluorescent probe is: 2C 84 h 84 N 56 o 18 @C 19 h 19 N 2 S 2 I. It is prepared from the helical fourteen-membered melon ring and 3,3-diethylthiocyanine iodide salt solution as raw materials. The probe can be used to detect Ba in aqueous solution 2+ . The water-soluble supramolecular fluorescent probe of the present invention can detect Ba in aqueous solution 2+ to test. The detection method has the advantages of low analysis cost, simplicity, sensitivity and speed.

Description

technical field [0001] The invention relates to the application of a probe reagent, in particular to a water-soluble supramolecular fluorescent probe and its preparation and application. Background technique [0002] Barium is a slightly lustrous silver-white alkaline earth metal. There are many kinds of barium compounds, such as barium chloride, barium carbonate, barium sulfate and barium hydroxide. Barium compounds are widely used in pigments, steel quenching, ceramics and glass industries. With the wide application of barium compounds, the discharge of barium-containing wastewater and waste to the environment during the production process will also increase, which will not only pollute the environment but also cause serious harm to the human body. Such as soluble barium can cause acute poisoning, symptoms of gastrointestinal irritation, hypokalemia, chest tightness, palpitations and so on. At the same time, when the barium compound enters the environment, it decomposes ...
