More Information
Summary:The invention relates to the development of polymerizable additives having high helical twisting power for liquid crystal compounds. 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 having polymerizable functional group to undergo esterification reaction. The additives can be reacted with polymerizable nematic host by light or heat to form crosslinked liquid crystal polymers. The additives are highly dissolved with polymerizable nematic host and the liquid crystal compounds with the additives can get larger helical twisting power and better light stability.
