摘要合成了具有不对称中心三氟甲基和三环杂环核的新型铁电液晶。这些化合物具有较大的自发极化，并在较宽的温度范围内表现出S∗c相。它们的性质很大程度上受间隔基团和核心部分结构的影响。
Abstract New ferroelectric liquid crystals with a trifluoromethyl group at the asymmetric centre and a three-ring heterocyclic core have been synthesized. These compounds possessed a large spontaneous polarization and exhibited a S∗c phase over a wide temperature range. Their properties were largely affected by the structure of the spacer group and the core part.
