摘要：
Esters and alkyltwistanecyanbenzenes of the tricycle (4.4.0.0(3,8)) decane (twislane) have been prepared and their mesomorphic properties were examined. All the compounds are optically active and some esters have a chiral mesophase. Possibility was investigated of the application of twistane esters to induce ferroelectricity in the tilted smectic C phase of pyrimidines. The twistanes induce weak spontaneous polarization, and the reason for this effect is discussed.
