Chiral Bis(camphorylidene)etylenediamine as Inducer of Helical Mesophase in Alkoxycyanobiphenyl Mixture

The mesomorphic, optical, dielectric, and orientation properties of nematic mixture CB-2 doped with chiral bis(camphorylidene)ethylendiamine were studied. The cleaning temperatures of mixtures were measured by polarization microscopy. The destabilization of the mesophase upon the introduction of a dopant was assessed. The helix pitch of the induced chiral nematic in mixtures was measured. The effect of a chiral dopant on the anisotropic characteristics of the mesophase was studied.
