Abstract
Mesomorphic, sorption and selective properties of stationary phase, based on nematic 4-metoxy-4'-etoxyazoxybenzene and chiral macrocyclic additive – methyl-β-cyclodextrin (10,07 mas. %) were investigated. Low values of para-meta- selectivity and absence of enanthyoselectivity for this system were marked for both straight (N) and reverse (N*) temperature processes. Thermodynamic sorption functions analysis showed that the investigated stationary phase could be described by strong «liquid crystal – macrocycle» interaction.

Keywords: liquid crystal, chiral macrocycle, composite sorbents, gas chromatography, selectivity, enanthyselectivity
