Problems solved by technology

Inhalation of 2,4,6-trichlorophenol through the respiratory tract or accidental ingestion of the esophagus can cause dysfunction of the body, so the compound is highly toxic
2,4,6-Trichlorophenol is highly irritating and can cause human poisoning if absorbed through skin contact
Although the traditional existing functional monomers screened in the prior art can form hydrogen bonds with template molecules, they lack the combined dominant signal transmission mode

[0053] 1. Preparation of fluorescent functional monomers

[0054] (1) Preparation of fluorescent functional monomers

[0055] figure 1 For the reaction flow chart, weigh 9,10-bischloromethylanthracene (1.375g) and 1-vinylimidazole (1.128g) and dissolve them in 30mL of anhydrous acetonitrile, heat up to 70°C, and keep at this temperature to condense and reflux 12h, after cooling, a light yellow solid was obtained. Then filter the obtained solid, and after repeated filtration and washing with anhydrous ether for 5 times, put the light yellow solid in a vacuum drying oven and dry it to constant weight, which is the fluorescent functional monomer—9,10-bis(1-vinyl- 3-imidazolium chloride) methyl anthracene.

[0056] The mass-to-charge ratio of the synthesized fluorescent functional monomer is 391.1854 (M-2Cl - ), showing that the molecular weight of the functional monomer is 462.1378.

Abstract

The invention discloses a fluorescent functional monomer, a molecularly imprinted polymer, and a preparation method and an application thereof, which belong to the technical field of a high polymer material. The fluorescent functional monomer 9,10-di(1-vinyl-3-imidazolium chloride) methylanthracene is dissolved in anhydrous acetonitrile by 9,10-dichloromethyl anthracene and 1-vinyl imidazole, thematerial is heated, and is subjected to backflow. Compared with 9,10-dichloromethyl anthracene, the fluorescence intensity the fluorescent functional monomer is significantly enhanced, can be used asa fluorescent monomer, and contains a group capable of recognizing template molecule 2,4,6-trichlorophenol. Further, the modified ionic liquid is used as the fluorescent functional monomer, and polymerized with the template molecule and a crosslinking agent under the action of an initiator, and forms the molecularly imprinted polymer. The molecularly imprinted polymer realizes double recognition of the target molecule, has high selectivity and disturbing ability, and has great application value in detecting 2,4,6-trichlorophenol in the environmental water body.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a novel fluorescent functional monomer and a molecularly imprinted polymer prepared by using the functional monomer. Background technique [0002] As an important chemical raw material, 2,4,6-trichlorophenol is widely used in fungicides, food and dairy product preservatives and solvents for polyester fibers. Inhalation of 2,4,6-trichlorophenol through the respiratory tract or accidental ingestion of the esophagus can lead to dysfunction of the body, so the compound is highly toxic. 2,4,6-Trichlorophenol is highly irritating, and it can cause human poisoning if absorbed through skin contact. Due to the frequent use of 2,4,6-trichlorophenol and its high risk of toxicity, it has been first included in the list of pollutants controlled by the European Union. [0003] At present, the methods for determining 2,4,6-trichlorophenol mainly include: electrochemical method, high...
