Effect of Molecular Polarity and Conjugated System on Antiferroelectricity in AFLC's

Series of pyrimidine and pyridine analogous compounds have been developed in order to interpret the relationship between stability of antiferroelectricity and the conjugation along the long axis of the molecule. On the appearance of antiferroelectricity, the longitudinal polarization of whole molecules promotes to stabilize the antiferroelectricity.
