Embodiment

[0025] A method for preparing a ratiometric luminescent carbon dot probe, comprising the following steps:

[0026] The synthetic route of the compound 2-hydroxy-5-methyl-1,3-benzenedicarbaldehyde:

[0027] .

[0028] 1) Synthesis of compound 2-hydroxy-5-methyl-1,3-phthalaldehyde

[0029] Dissolve p-cresol (10 mmol) and hexamethylenetetramine (20 mmol) in a TFA (15 mL) solution, and react under reflux at 110°C for 24 hours under the protection of argon. The reaction solution was cooled to room temperature, hydrochloric acid (4 M, 66 mL) was added, stirred at room temperature for 10 minutes, extracted with dichloromethane and saturated brine, washed three times with saturated brine, the organic layer was rotary evaporated under reduced pressure to remove the solvent, and subjected to column chromatography ( The eluent was dichloromethane), purified to obtain a white flocculent solid, and dried in vacuum to obtain the compound 2-hydroxy-5-methyl-1,3-benzenedicarbaldehyde (yie...

Abstract

The invention belongs to the technical field of analytical chemistry and particularly relates to a preparation method and an application of a ratiometric luminescent carbon-dot probe. The ratiometricluminescent carbon-dot probe is a carbon-dot luminescent nanomaterial prepared from p-cresol, hexamethylenetetramine and o-phenylenediamine as raw materials, detects zinc ions in a ratiometric luminescent manner, serves as a novel ratiometric luminescent nano-sensor for detecting the zinc ions, has the advantages of good stability, good anti-interference performance and the like and can be used for detecting the zinc ions in a solution.

Description

technical field [0001] The invention belongs to the technical field of analytical chemistry, and in particular relates to a preparation method and application of a ratiometric luminescence carbon dot probe. Background technique [0002] As one of the essential micronutrients for the human body, zinc ions play a vital role in physiological processes such as DNA replication and repair, gene expression and cell metabolism. Therefore, the detection of zinc ions has attracted extensive attention from chemists, biologists, and physiologists in recent years, but due to the lack of obvious spectral and magnetic signals of zinc ions, common analytical techniques such as UV-vis spectroscopy, Mössbauer Spectroscopy, nuclear magnetic resonance, electron paramagnetic resonance spectroscopy, etc. are difficult to detect zinc ions. [0003] With the continuous development of fluorescent molecular probes, many organic molecular probes of zinc ions have been synthesized. In addition to orga...
