Abstract

The invention discloses an azothiourea-type anion receptor, which is characterized in that: the molecular structure formula of the azothiourea-type anion receptor is shown in formula 1. The invention also discloses a preparation method of the azothiourea anion acceptor. The present invention can accurately and rapidly identify whether the halogen anion is F- by observing the ultraviolet spectrum of the anion acceptor. At the same time, the azothiourea anion acceptor of the present invention can also convert the anion acceptor into a cis structure under the irradiation of visible light, thereby identifying whether the added dicarboxylic acid anion is azelaic acid ion. The preparation method of the anion receptor of the present invention is easy, and the detection method only needs to be detected by naked eye observation and ultraviolet light absorption detection, the detection method is simple, the anion receptor consumption is small, the cost is low and easy to realize, and it has strong practicability.

Description

technical field

[0001] The invention relates to the field of anion receptors, in particular to an azothiourea-type anion receptor and its preparation method and application. Background technique

[0002] Anions are ubiquitous in organisms and human environments, so anion recognition plays an important role in the fields of life sciences, medical sciences, and environmental sciences. For example, in life sciences, enzyme substrates and coenzymes are mostly anions, DNA, the carrier of genetic information, is a polyanion, and dicarboxylate anions play an important role in many metabolic processes. In medical science, the determination of chloride ion concentration in the body is also extremely important for the detection and treatment of patients with alveolar fiber disease; acetate can treat uremia, and excess acetate in the body can cause vomiting, low blood pressure and even death. In environmental science, excessive use of phosphorus and nitrogen fertilizers may lead to eu...
