With VIMF as a polymerizable monomer, VIMF bonded silica gel chromatographic stationary phase(Sil-VIMF)material was prepared by thiol-ene click reaction. Fourier transform infrared spectroscopy and thermogravimetric analysis were used for characterization the Sil-VIMF material. The results proved the successful preparation of Sil-VIMF stationary phase material. The retention mechanism investigation results show that the Sil-VIMF stationary phase has a hydrophilic interaction chromatography retention mechanism. Chromatographic separation performance results show that Sil-VIMF stationary phase can achieve good separation for amides, nucleosides/nucleobases, and anilines. The column efficiency can reach 79 200 N/m. The Sil-VIMF stationary phase was further used for the separation and analysis of gastric cancer cell membrane lipid extracts. The effective separation and analysis of phosphatidylcholine and phosphatidylethanolamine was achieved, indicating good application potential.
