Abstract

A bonded silica stationary phase (SP 1) was prepared by connecting N-(3,5-dinitrobenzoyl) aminoundecylsilane to silica gel. The stationary phase was applied in resolving a liquid crystal mixture with a reversed phase high performance liquid chromatography (HPLC) mode and the chromatographic resolution results were compared with those on an octadecylsilane (ODS) column. From the comparison of the resolution results on SP 1 and the ODS column, we found the new stationary phase was better than the ODS column in resolving a liquid crystal mixture and the elution orders of some liquid crystal were changed. The better resolution and the change in the elution orders on the new column might be originated from additional π-π interaction between the π-acidic 3,5-dinitrobenzoyl group of the stationary phase and the π-basic aromatic group of liquid crystals.
