Embodiment

[0026] Examples The fluoroboron compound of the present invention has the following structure:

[0027]

[0028] It is prepared according to the following steps:

[0029] (a) Sodium 3-nitrobenzenesulfonate (17.5 g, 77.7 mmol), boric acid (2.4 g, 38.8 mmol) and ferrous sulfate heptahydrate (1.4 g, 0.5 mmol) were added to 23.1 mL of 98% sulfuric acid by mass middle. After cooling to 0 °C, glycerol (12.5 mL), 2-amino-6-picoline (4.3 g, 40.0 mmol) and hot water (50 °C, 22.5 mL) were slowly added to the above mixture. Heat to 135 °C and reflux for 4 hours to cool to room temperature. Adjust the pH value, dissolve the organic phase with chloroform, and purify by column chromatography (200-300 mesh) to obtain the product.

[0030] Characterized as follows: 1 H NMR: δ H (400 MHz; CDCl 3 ; 4 Si) 9.08(d, 1H), 8.15 (m, 1H), 8.08(d, 1H), 7.42 (m, 1H), 7.28 (d, H), 2.82 (s, 3H). 13 C NMR: δ C (100 MHz, CDCl 3 ): 163.06, 155.96, 153.31, 136.86, 136.65, 123.03, 121.37, 120.76,...

Abstract

The invention discloses a fluoboride fluorescent derivative, and a synthetic method and an application thereof, and belongs to the metal ion detection field. The molecular structure of the fluoborate fluorescent derivative is represented by a formula shown in the specification. The fluoborate fluorescent derivative is used for the fluorescent sensing and analysis of cadmium ions in the environment, allows boron atoms to be exchanged with the cadmium ions after the identification of the cadmium ions, has a good cadmium ion selectivity, has a strong anti-interference capability to other metal ions, can avoid the interferences of other metal ions, especially the interferences of zinc ions, and allows the cadmium ions to be rapidly distinguished from a plurality of metal ions.

Description

technical field [0001] The invention relates to a fluorescent boron fluoride derivative and its synthesis method and application, belonging to the field of metal ion detection. Background technique [0002] Cadmium exists in minerals in the form of oxides or salts in the natural environment. It is widely used in industrial production fields such as fertilizers and cadmium-nickel batteries, and the environmental pollution caused by it is becoming more and more serious. Cadmium is lost to the environment and easily enters the organism or human body through food. Cadmium accumulates in the human body, and its latent time can be as long as 10 to 30 years. It accumulates over time and causes harm to organisms or human body. According to reports, when the cadmium in water exceeds 0.2mg / L, the residents drink water for a long time and ingest cadmium-containing substances from food, which can cause "bone pain disease". The metal cadmium has very low toxicity, but its compounds are ...
