摘要：

(S)-1-methylheptyl 2-[4-(4-dodecyloxybenzoyloxy)phenyl]pyrimidine-5-carboxylate and its racemic modification were synthesized. Through miscibility studies, investigations of defect textures, differential scanning calorimetry and electrical held studies, we conclude that this material exhibits an antiferroelectric twist grain boundary TGBC(A)* analogue of the Abrikosov flux phase found in superconductors. This outcome represents the addition of a new frustrated state of matter to the family of twist grain boundary phases. This novel phase was found to exist between the isotropic liquid and the antiferroelectric smectic C* phase.
