Abstract:

To explore the affinity recognition ability of the constructed boronic acid-functionalized metal-organic framework(MOF)-derived surface imprinting material(FSU-BA@MIP) for the substrate, the boron affinity between 3-carboxyphenylboric acid ligand of the metal-organic framework(UiO-66-BA) of FSU-BA@MIP and salbutamol was calculated and explained. The density functional theory(DFT) calculation and selectivity test were used to evaluate the selectivity mechanism of FSU-BA@MIP for salbutamol. The results show that the hydrogen bond between the charged 3-carboxyphenylboric acid and salbutamol makes them have a strong force, and it is easier to form boronic acid cyclic ester. In addition, compared with the competing substances, the lowest binding energy and reaction energy of UiO-66-BA and salbutamol indicate that FSU-BA@MIP has a specific adsorption of salbutamol, and the analytical results are consistent with the highest adsorption data of salbutamol obtained from the experiment. Therefore, UiO-66-BA is an ideal boric acid functional material for the analysis of cis-diol compounds.
