Here,silica microspheres were decorated with two-dimensional metal-organic frameworks(2 d mofs)nanosheets and ionic liquids,and evaluated as the mixed-mode stationary phase for chromatographic *** ionic liquids were used to assist the synthesis of 2 d mofs nanosheets,and also acted as adhesives among the nanosheets and *** contrast with the 2 d mofs-based column without ionic liquids and commercial columns,the prepared column exhibited enhanced chromatographic separation performance for partially hydrophilic compounds such as alkaloids,sulfonamides and antibiotics,*** addition to excellent chromatographic repeatability and stability,it has also been verified that the composites could be easily and repeatedly *** relative standard deviation of the retention time of the same type of analyte between the three batches of materials was ranging from 0.21%to 1.7%.In short,these results indicated that the synthesized composites were promising separation material for liquid chromatography,which made it possible to broaden the application of 2 d mofs in the field of chromatography.
