Abstract
The retention behaviour of geometrical isomers and Rohrschneider compounds was measured in the nematic range of liquid crystalline stationary phases having different chemical structures, in order to determine the influence of these structures on the polarity and selectivity of the phases. It was found that lateral substituents in mesogenic molecules effect a change in selectivity. The polarities of these phases are compared with those of conventional stationary phases, and the strong influence of the terminal groups of the liquid crystal molecules on Δ I values is discussed.
