In this work, a novel imidazolium bonding method was proposed for the synthesis of hydrophilic interaction liquid chromatography (HILIC) stationary phases. One obtained stationary phase (SilprAprImCl) was derived from direct reaction between N-(3-aminopropyl)-imidazole and 3-chloropropylated silica gel. Other two materials (SilprAprImBF4 and SilprAprImTf2N) were obtained from SilprAprImCl by ion exchange reaction, respectively. Fourier-transform infrared spectroscopy and elemental analysis afforded the proofs of successfu
