Аннотация:
Quaternary ammonium salts and organotriphenylphosphonium halides have been synthesized. Their ions can have an orienting effect on liquid crystals. The solubility of the obtained compounds in the nematic liquid crystal – 4-cyano-4'-pentylbiphenyl (5CB) has been studied. It was shown that two ammonium salts both dissolve in the nematic and also dissociate into ions. At that, the anions moving in electric field can modify the boundary conditions. This fact allows using these compounds for the ion-surfactant method of controlling liquid crystal materials.
