Embodiment 1

[0037] A method for preparing a metal frame temperature-sensitive molecularly imprinted polymer, comprising the following steps,

[0038] 1) Weigh 0.78mmol of yttrium acetate, 0.2mmol of ytterbium acetate and 0.02mmol of erbium acetate and dissolve them in 6mL of oleic acid and 17mL of octadecene. The mixture is heated to 160°C to form a transparent solution, which is naturally cooled to room temperature. Add 2.5mmol NaOH and 4mmol NH dropwise 4 A solution of F in 10 mL of methanol was stirred at room temperature for 30 min. Then, methanol was gradually removed by heating. After vacuuming at 100°C for 10 minutes, it was heated to 300°C under the protection of argon and maintained for 1h. After the resulting solution was naturally cooled, the oil-soluble up-converting nanoparticles were precipitated in ethanol;

Abstract

The invention provides a method for preparing a metal frame temperature-sensitive molecularly imprinted polymer, which is used for enriching or sensing bovine hemoglobin. The method includes the steps of preparing a metal frame compound with up-converting fluorescence, introducing a temperature-sensitive monomer, etc. . The invention introduces strong fluorescent UCNPs and MOF with large specific surface area into the molecular imprinting technology, and the prepared composite material can be used for enrichment and sensing of bovine hemoglobin. At the same time, a temperature-sensitive monomer is introduced, so that the composite material has a reversible adsorption / release function with temperature, and has broad application prospects.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a method for preparing a metal frame temperature-sensitive molecularly imprinted polymer. Background technique [0002] Metal-organic framework (MOF) is a porous material that has developed rapidly in recent years. Compared with traditional inorganic porous materials, MOF materials have larger porosity and specific surface area, especially adjustable pore size and variable The functional group has attracted the attention of more and more scientific researchers. At present, MOF materials are widely used in hydrogen storage, biosensing, material adsorption and separation, etc. However, MOF materials lack specificity and have certain limitations in enriching specific targets. [0003] Molecular imprinting technology refers to the process of using a specific target molecule as a template to prepare a polymer with specific recognition properties for the molecule. Compar...
