Supramolecular Planar Liquid Crystal Systems on Carbon Surface as Universal Isomer-Selective Adsorbents

Abstract

The features of the monolayer structure of supramolecular liquid crystals (LC) and «supramolecular LC − β-cyclodextrin» bilayers placed on a flat carbon surface are presented. The application possibility of these materials in gas-adsorption chromatography is discussed. It is shown that self-organizing ordered planar structures of these modifiers on the adsorbent-carrier carbon surface provide high meta-/paraand ortho-/para-selectivity as well as enantioselectivity to non-polar and polar optical isomers.
