180. Some Novel Nematic Materials Bearing Two Lateral Nitrile Functions

Article abstract of DOI:10.1002/hlca.19830660625

More than fifty esters of 3-alkyl-6-hydroxy-1,2-benzenedicarbonitrile have been prepared.The new esters exhibit stable nematic phases of high negative dielectric anisotropy.The relationship between the clearing points of the esters and the various ring they incorporate is the same as that normally observed for nematic materials of positive dielectric anisotropy.
