Pillar[5]arene/isophthalic acid-1,8-naphthalenedicarboximide complex, and preparation and application thereof

Abstract

The invention relates to a pillar[5]arene / isophthalic acid-1,8-naphthalenedicarboximide complex. The complex uses copillar[5]arene as a subject, isophthalic acid-1,8-naphthalenedicarboximide as an object and C-H...PI and electrostatic force as driving force; and a part of isophthalic acid-1,8-naphthalenedicarboximide with negative charges is included into the cavity of copillar[5]arene through self-assembling in an alkaline environment, so the process of assembling of the subject and the object is finished. After aluminum ions are added into a solution of the pillar[5]arene / isophthalic acid-1,8-naphthalenedicarboximide complex, the fluorescence of the complex solution is enhanced and yellow fluorescent light is given out; and when anionic CN<-> is further added, the fluorescence of the complex solution undergoes a red shift and green fluorescent light is given out. Therefore, the pillar[5]arene / isophthalic acid-1,8-naphthalenedicarboximide complex is applicable as a novel supramolecular fluorescence sensor for continuous detection of Al<3+> and CN<-> in environment.

Description

technical field [0001] The invention relates to a column 5 aromatic hydrocarbon / isophthalic acid-1,8 naphthalimide complex; the invention also relates to a column 5 aromatic hydrocarbon / isophthalic acid-1,8 naphthalimide complex The invention relates to the application of the compound in the continuous detection of aluminum ions and cyanide ions, and belongs to the technical field of ion detection. Background technique [0002] As we all know, ions play an important role in the fields of chemistry, biology, medicine and process flow. Usually, most biological and environmental reactions are carried out in aqueous systems, therefore, it is very important to detect ions in aqueous solutions. So far, a variety of useful strategies or methods, such as designing water-soluble receptors or designing host / guest complexes to be water-soluble sensors, have been used to develop sensors that can be effectively applied in water. However, these methods have some problems. First, since ...

In addition, the occurrence of chronic cyanide poisoning is also related to the overall nutritional status of the body, such as vitamin B12 deficiency, protein malnutrition, especially the lack of sulfur-containing amino acids can make the body use CN － Detoxified S 2 o 3 2- , S 2- and SH - Reduction of these factors can make CN uptake in the body － Increased toxicity, resulting in a range of symptoms and signs of chronic poisoning
