| description | The invention relates to the development of the additives for liquid crystal compounds with optical activities having high helical twisting power. The structure of the additives for the liquid crystal compounds is the ester compound that has the natural occurring organic multi-ring alcohols with optical activities. Terpenol, Borneo, Cinchonidine, or Quinine as starting materials is reacted with another reactants whose core structures are similar with the liquid crystal compounds to undergo esterification reaction. The additives are highly dissolved with nematic host and the liquid crystal compounds the additives can get larger helical twisting power and better light stability. |
