Application of liquid crystals in liquid chromatography. From low- to high-molecular-weight liquid crystals [Review]

摘要

The use of liquid crystals as stationary phases for liquid chromatography is reviewed. The synthetic pathways used for covalent immobilization of low-molecular-weight liquid crystals on the silica-gel surface are discussed. The techniques used to characterize stationary phase structure are also presented. Finally, the trend for replacement of low-molecular-weight liquid crystals by liquid-crystalline polymers, either coated or bonded, is described. Examples are given of the separation of specific chemical compounds on liquid-crystalline stationary phases. [References: 66]
