Antiferroelectric-Like and Large Pyroelectric Behaviors of an Organic Compound: (S)-(+)-4-{[(1-Methylheptyl)Oxy]Carbonyl}Phenyl-4-(Hexyloxy)Benzoate



Until now, the studies of anti-ferroelectric and pyroelectric property were focused on inorganic materials and some anti-ferroelectric liquid crystals. In this work, we reported an organic compound: (S)-(+)-4-{[(1-methylheptyl)oxy]carbonyl}phenyl-4-(hexyloxy)benzoate, that was discovered to exhibit antiferroelectric-like and large pyroelectric behaviors near the phase transitions. Its electrical properties were investigated by dielectric, pyroelectric, and P-E hysteresis loop spectra. The maximum value obtained for the pyroelectric coefficient p was 384 nC cm−2 k−1. The material is promising in the field of thermal-electrical switch or pyroelctric detection.
