Abstract

The invention provides a preparation method for a thermo-sensitive type molecularly imprinted polymer with a metal frame. The method is used for enriching or sensing bovine hemoglobin and comprises the following steps: preparing a metal frame compound with upconversion fluorescence; introducing a thermo-sensitive monomer. According to the preparation method for the thermo-sensitive type molecularly imprinted polymer of the metal frame, UCNPs with strong fluorescence and MOF with larger specific surface area are introduced into a molecular imprinting technology, and a prepared composite material can be used for enriching or sensing the bovine hemoglobin. Meanwhile, the thermo-sensitive monomer is introduced, so that the composite material has a temperature-based reversible adsorption / release function and has a broad application prospect.

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...
