摘要
Liquid-crystalline ionic polyethylenimine derivatives have been synthesized, and their thermal properties and dielectric behavior have been studied. They exhibited thermotropic smectic phases. The ferroelectric like behavior was confirmed by dielectric measurement and observation of the hysteresis loop with the Sawyer-Tower circuit.
