A novel ferroelectric liquid crystal, (S)-bis(2-methylbutyl) 3,3′-[1,2-ethanediylbis[oxy-4,1-phenylenemethylidyne nitrilo-4,1-phenylene]]bis[2-propenoate] (EBOPBP) was prepared, which are composed of two chiral mesogenic groups interconnected by a very short flexible spacer chain. EBOPBP exhibts a chiral smectic C phase (Sc*). From an electrooptical effect due to a deformation of helical structure in the Sc* state, the rise time (τr) was estimated to be 240 μs at 180 °C.
制备了一种新型铁电液晶--(S)-双(2-甲基丁基)3,3′-[1,2-乙烷二基双[氧-4,1-亚苯基甲基硝基-4,1-亚苯基]]双[2-丙烯酸酯](EBOPBP),它由两个手性介原基团组成,并通过一个非常短的柔性间隔链相互连接。EBOPBP 显示出手性平分 C 相(Sc*)。根据 Sc* 状态下螺旋结构变形产生的电光效应,在 180 °C 时的上升时间(τr)估计为 240 μs。
