| Abstract
| - The thermodynamic and surface properties of four structurally related thermotropic liquid crystals (LC)were investigated to understand their organization at gas−liquid and gas−solid interfaces. In this study,LC with a benzoyloxy azobenzene mesogenic core substituted with heptyloxy and/or dioxyethylene ethergroups were used. The propensity of the LC to form self-assembled multilayers was demonstrated in thefilms spread at the air/aqueous interface using the Langmuir technique and Brewster angle microscopyand on the solid surfaces of Chromosorb WHP and silica, using differential scanning calorimetry. On thebasis of the results obtained, a molecular recognition mechanism underlying separation processes usingLC as selectors in gas chromatography is proposed.
