Abstract
The invention provides an organic compound containing a Schiff base unit and its preparation method and use. Compound I is obtained by reflux reaction of 5-bromosalicylaldehyde and hydrazine hydrate; compound I, triboric acid benzaldehyde, inorganic base and tetra Triphenylphosphine palladium is heated and reacted under the protection of nitrogen to obtain compound II; compound II, 9,10-phenanthrenequinone and ammonium acetate are refluxed to obtain the organic compound containing Schiff base units shown in the formula (I) of the present invention . The ion detection performance of the organic compound containing the Schiff base unit is improved by introducing the Schiff base unit and the large conjugated aromatic compound into the compound structure.
Description
Organic compound containing Schiff base unit and preparation method and use thereof technical field The present invention relates to metal ion detection field, particularly a kind of organic compound containing Schiff base unit and preparation thereof Preparation methods and uses. Background technique With people's attention to living environment and own health, some detection items related to people's daily life Detection methods also tend to be simple and convenient, and ion detection materials have a wide range of applications because they are closely related to daily life. use. Iron ions are widely present in the environment, especially when Fe 3+ The higher content will have a great impact on the water quality, The content of suspended solids in the water will increase greatly, and it will also block the formation and cause reservoir damage. In addition, ferric iron is very important to the human body, and iron is an important element that composes human...
