Researchers from the Chromatographic Materials and Analytical Technology Group of Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences used electrostatic self-assembly in-situ growth and layered solvothermal methods to separate three-dimensional bimetallic MOF (ZnCo MOF) and two-dimensional MOF nanosheets (2D FDM-23).
) Modified on the surface of silica gel to prepare hydrophilic core-shell composite chromatographic packing material, which realizes the efficient separation of active ingredients of various hydrophilic natural products such as alkaloids and oligosaccharides
.
? This method expands the application of 3D bimetallic MOF and 2D MOF in liquid chromatography for the first time, and further expands the application range of MOFs
.
The related results were recently published on Analyst (2020, 11,3851-3856) and Talanta (2021, 222,121603).
Doctoral student Si Tiantian is the first author of the paper, and associate researcher Wang Shuai and researcher Guo Yong are the co-authors.

3D MOF@silica? and 2DMOF@silica? Schematic diagram of the preparation of composite materials? Subsequently, the researchers selected high heat resistance metal organic framework (MOF-235) and polyvinylpyrrolidone (PVP), poly Ethylene glycol (PEG) hydrophilic polymer is modified on the surface of silica gel by solvothermal method and high temperature program calcination method to synthesize a hydrophilic/hydrophobic core-shell composite chromatography packing
.
? This packing combines MOF- The hydrophobicity of 235, the π-interaction, the hydrophilicity of PVP, PEG and the hydrophobicity after partial carbonization
.
It has achieved good separation effects on a variety of hydrophilic/hydrophobic compounds and has been successfully applied to the separation of sulfonamide antibiotics in honey Detection
.
? This research provides a new idea for the preparation of multi-interaction chromatography packing materials.
By changing the types of MOF and polymers, the prepared packing materials are expected to be applied to the separation and detection of different target components in actual complex systems
.
Related results have been published recently.
