synthesized new chiral liquid crystalline (LC) organic radical compounds 2 and 3, which are the derivatives of the previously reported compounds 1 containing a chiral cyclic nitroxide unit and an ester group in the mesogen core, and their ferroelectric properties have been studied. The enantiomerically enriched (2S,5S)-2 and (2S,5S)-3 showed an SmC * phase for which their ferroelectric properties such as spontaneous
我们合成了新的手性液晶(LC)有机自由基化合物 2 和 3,它们是先前报道的化合物 1 的衍生物,它们在介晶核中含有一个手性环状硝基氧单元和一个酯基,并对其铁电性能进行了研究。对映体富集的 (2S,5S)-2 和 (2S,5S)-3 显示出 SmC * 相,将它们的铁电特性如自发极化 (Ps) 和倾斜角 (θ) 与 (2S,5S) 进行了比较)-1。
