Embodiment

[0021] (1) Synthesis of 1,10-phenanthroline-5,6-dione

[0022] Measure 70mL of concentrated sulfuric acid into the flask, add magnets, cool in an ice-water bath, slowly add 4.95g (25mmol) o-phenanthroline monohydrate under stirring conditions, stir for 10min, after the solution is fully dissolved, the solution turns light yellow, and then slowly add 10g Potassium bromide and 35mL concentrated nitric acid, remove the ice-water bath after completion, continue to stir at room temperature for 30 minutes, then gradually raise the temperature to 130°C, and keep the temperature for 2 hours (this step will produce reddish-brown bromine vapor, attention should be paid to tail gas treatment) . Cool the reaction solution to obtain a reddish-brown transparent solution. Pour the reaction solution into about 300 g of crushed ice, adjust the pH to 6.5 with sodium carbonate, and a large amount of foamy suspended solids will appear. Filter, dissolve the solids in hot water and filter while hot...

Abstract

The invention discloses a 1,10-o-phenanthrolin-5,6-dione phenylhydrazine anion receptor and an application thereof. The structural formula of the 1,10-o-phenanthrolin-5,6-dione phenylhydrazine anion receptor is represented by a formula shown in the description. The 1,10-o-phenanthrolin-5,6-dione phenylhydrazine anion receptor is a good receptor for identifying anions and can be applied to the identification on the anions, i.e., F<-> and OH<->, and an imino group (NH) in a molecular structure is an anion binding site.

Description

technical field [0001] The invention belongs to the technical field of anion recognition, and in particular relates to a 1,10-phenanthroline-5,6-diketone anion acceptor and application thereof. Background technique [0002] With the development of economy and science and technology, anions have more and more important influences in research fields such as medicine, life sciences, environmental protection, agricultural production and industrial catalysis, such as fluorine-containing compounds are used to prevent dental caries, add fluoride to drinking water and other In oral hygiene products; nitrate and sulfate ions are the main causes of acid rain; polyanion DNA can transmit genetic information of organisms; excessive use of phosphate fertilizers in agricultural production causes eutrophication of rivers, etc. Therefore, the anion recognition technology and the synthesis of anion receptors have important practical value and broad development prospects. The demand for highl...
