In a process of detecting pesticide paraquat by adopting the material, thesensitivity is high, the detection selectivity is good, and the fluorescent porous material has good application prospects in the field of material science.

Description

technical field [0001] The invention relates to the technical field of synthesis of fluorescent porous materials, in particular to a fluorescent porous material, a synthesis method and an application thereof. Background technique [0002] Fluorescent porous materials have been increasingly studied in the field of many optical devices. As a novel fluorescent probe material, they usually exhibit the advantages of high sensitivity, good selectivity, short response time, and simple operation, and some fluorescent probe materials have Recyclability can realize fluorescence detection in different solvents and effectively promote the commercial application of fluorescent porous materials. Therefore, it is a meaningful research to construct fluorescent porous probe materials with high sensitivity and high stability. [0003] At present, in agricultural production, the excessive use of pesticides is seriously endangering our health. According to the literature survey, paraquat (1-1-d...

[0003] At present, in agricultural production, the excessive use of pesticides is seriously endangering our health. According to the literature survey, paraquat (1-1-dimethyl-4-4 bipyridyl cationic salt) is a fast-killing herbicide, It can be quickly absorbed by green plants to make them die, so farmers will spray herbicides during the growth of crops in order to quickly weed weeds. Although, herbicides have a killing effect on crops, and then the medicinal properties of herbicides will be absorbed by crops, so , the crops will contain a certain amount of toxicity, and long-term consumption will cause great harm to the human body. However, due to the low content in the crops, and there is no testing material on the market that can quickly and accurately detect the content of paraquat
