摘要：

The synthesis and specific properties of a new family of fluorinated ferroelectric liquid crystalline polymers of the general structure 1, are described. These materials exhibit quick response time (<10 ms) and large spontaneous polarization (40-70 nC/cm2) (90 °C). Adiscussion of the response time-structure relationships is given. The response time becomes faster as the achiral chain connecting the mesogen to the polymer backbone and the chiral chain length becomes shorter. Especially, it is found that a trifluoromethyl group on the stereogenic center enhanced the response time. © 1990, American Chemical Society. All rights reserved.
