英文摘要	two tricationic ionic liquids were prepared and then bonded onto the surface of supporting silica materials through "thiol-ene" click chemistry as new stationary phases for high-performance liquid chromatography. the obtained columns of tricationic ionic liquids were evaluated respectively in the reversed-phase liquid chromatography (rplc) mode and hydrophilic interaction liquid chromatography (hilic) mode, and possess ideal column efficiency of 80,000 plates/m in the rplc mode with naphthalene as the test solute. the tricationic ionic liquid stationary phases exhibit good hydrophobic and shape selectivity to hydrophobic compounds, and rplc retention behavior with multiple interactions. in the hilic mode, the retention and selectivity were evaluated through the efficient separation of nucleosides and bases as well as flavonoids, and the typical hilic retention behavior was demonstrated by investigating retention changes of hydrophilic solutes with water volume fraction in mobile phase. the results show that the tricationic ionic liquid columns possess great prospect for applications in analysis of hydrophobic and hydrophilic samples.
