Abstract

The invention provides a fluorenyl fluorescent polymer and a preparation method thereof. The preparation method comprises the following steps that step one, (9,9-bi(6-bromine hexyl)-2,7-bifluorene aldehyde) and (1S,2S)-hexamethylene diamine are used as raw materials, and an intermediate polymer is obtained under the action of anhydrous LiCl as a catalyst; and step two, the prepared intermediate polymer is dissolved in a solvent, a trimethylamine aqueous solution is added, and the fluorenyl fluorescent polymer is obtained. According to the fluorenyl fluorescent polymer and the preparation method thereof, iron ion detection is simple, convenient and safe, the operation is convenient, selectivity is high, a result is not interfered by other ions, a linear test range is wider, and the fluorenyl fluorescent polymer and the preparation method thereof are especially applicable to the microscale and trace detection; and according to the fluorenyl fluorescent polymer and the preparation methodthereof, sensitive, rapid and accurate detection of the content of the iron ions can be realized in life bodies and under various natural and artificial aqueous solution environments, and important application value and wide application prospects are achieved in the fields such as medical treatment, industrial engineering, agriculture, building and food.

Description

technical field

[0001] The invention relates to a polymer and a preparation method thereof, in particular to a fluorenyl fluorescent polymer and a preparation method thereof, and belongs to the field of metal ion detection. Background technique

[0002] Iron is the fifth most abundant element on earth. It is abundant in reserves and widely used. Iron and steel materials account for 95% of the world's total metal production. Iron is also an essential element for our body and is an integral part of the composition of human and animal hemoglobin. Iron deficiency anemia occurs when the body lacks iron. However, excessive iron in cells can induce a large amount of reactive oxygen species to cause fatal damage to cells. Excessive iron ions in brain tissue can cause severe oxidative damage in the brain, and even lead to epilepsy.

[0003] It is of great significance to the detection of iron ions. The traditional detection of iron ions mainly includes o-phenanthroline method (nee...
