Abstract

The invention discloses a Th<4+> fluorescent identification material based on a 1,1'-bi-2-naphthol derivative and a preparation method and application of the fluorescent identification material. The preparation method includes the following steps: preparing an intermediate product (R)-2,2'-bis(methoxymethoxy)-1,1'-binaphthyl which is called RDB for short; preparing a target product 1-bis(3'-(2'-hydroxy-4'-(2'-hydroxy-1'-naphthyl)naphthyl))benzyl alcohol which is called RDB-B for short; preparing a complex of Th<4+> and the 1-bis(3'-(2'-hydroxy-4'-(2'-hydroxy-1'-naphthyl)naphthyl))benzyl alcohol; and preparing the Th<4+> fluorescent identification material based on the 1,1'-bi-2-naphthol derivative. The preparation method provided by the invention can synthesize the high-molecular polymericmaterial, the material can be reused, the internal structure is not damaged, and the problems that a small-molecular fluorescent material is easy to drop and cannot be reused are solved.

Description

technical field

[0001] The invention belongs to the technical field of chemical industry, in particular, relates to a compound based on binaphthol derivatives Th 4+ Fluorescence recognition material and its preparation method and application. Background technique

[0002] Thorium is a radioactive element widely distributed on the earth's crust, and it has a wide range of uses in industrial and agricultural production such as the nuclear industry, aerospace, and medical care. However, the mining and use of thorium produces a large amount of waste, which is toxic and radioactive, and is one of the most dangerous environmental pollutants that seriously endangers health. If not handled properly, it will cause serious harm. Studies have shown that continuous exposure to thorium may increase the risk of lung, pancreatic or bone cancer in humans and cause changes in genetic material. Therefore, a simple and convenient detection method for Th 4+ method is particularly important....
