This article belongs to the Special Issue Development of Liquid Crystalline Stationary Phases for Liquid and Gas Chromatographic Separations

Abstract: In order to investigate the separation mechanism of liquid crystals stationary phases based on an oxadiazole moiety, new 1,3,4-oxadiazole derivative as side mesogenic arm in liquid crystals was prepared, and its structural spectroscopic data were studied in this paper. A powerful indication about the relationship between molecular structure and ali... Show More

This article belongs to the Special Issue Development of Liquid Crystalline Stationary Phases for Liquid and Gas Chromatographic Separations

Abstract: Nematic liquid crystals have shown particular selectivity and sensitivity as stationary phases for the separation of isomers having similar volatilities. Because of their unique selectivity towards rigid solute isomers, liquid crystal stationary phases were considered at one time to be a very promising class of materials that give the gas chromatog...
