Abstract
Nematic lyomesophases with discotic (ND) and cylindrical (NC) micelles in complex multicomponent lyotropic systems based on alkyltrimethylammonium bromide detergents have been identified by the 1H-2H-, and 13C-NMR methods and polarizationoptical microscopy. The difference in the structures of the ND and NC nematic phases is especially pronounced in the 13C-NMR spectra. Addition of chiral dopants to the lyomixture facilitates formation of the ChD and ChC cholesteric phases. According to the 13C-NMR spectra, the micellar mobility in the cholesteric lyomesophases decreases in comparison with the nematic ones. The alignment of lyocholesterics under the action of an external magnetic field is found.
