Abstract

The invention discloses a dopamine derivative, a molecular imprinted polymer and preparation methods and application thereof. The dopamine derivative comprises dansyl dopamine, carbazole sulfonyl dopamine and the like. The dopamine derivative is synthesized from a fluorescent color former precursor and dopamine through sulfonation reaction. The fluorescent molecular imprinted polymer is prepared by using the fluorescent dopamine derivative, integrates specific sample pretreatment and fluorescence detection and is linked with an ELISA (Enzyme-Linked Immuno Sorbent Assay) plate, so as to form a fluorescent sensor, and series acidic organic pollutants, including bisphenol A and 2,4-dichlorophenoxyacetic acid, in an environmental water sample are directly assayed according to the change of fluorescence quenching values before / after sample application.

Description

technical field

[0001] The invention belongs to the technical field of molecular imprinting, and more specifically relates to a preparation method and application of a dopamine derivative and a molecular imprinting polymer. Background technique

[0002] Molecular imprinting technology uses the target molecule to be separated as a template molecule, polymerizes it with a cross-linking agent in a polymer monomer solution to prepare a monomer-template complex, and then removes the template molecule by physical or chemical means to obtain " Molecularly imprinted polymers (MIPs) that have the spatial structure of target molecules. Molecular imprinting technology is a new technology for preparing polymers with selective recognition ability for target compounds. It has the advantages of predictability, selectivity, stability, etc. It is used in chromatographic separation, solid phase extraction, catalysis, drug controlled release, and detection of environmental residue Pollutants ...
