Abstract
Liquid crystalline materials on the base of rod-like mesogens with hydrogen bonds were reviewed. On the base of orientational ordering of liquid crystalline and isotropic solutions with proton donor solutes the structure of H-complexes (supermolecules) was estab-lished. The stability of supermolecules Shiff base – proton donor in different phases was es-timated by means of NMR and ab initio calculations. The influence of H-bonding on the conformational state and mesomorphic properties was shown.
Keywords: liquid crystalline materials, rod-like mesogens with hydrogen bonds, proton donor solutes, mesomorphic properties
