Smectic liquid crystals with âde Vries-likeâ properties are characterized by a maximum layer contraction of â¤1% upon transition from the non-tilted SmA phase to the tilted SmC phase. We show herein that one can systematically increase the âde Vries-likeâ character of a smectic liquid crystal by tuning the frustration between SmA- and SmC-promoting elements according to established structureâproperty relationships.
具有 "类德弗里斯 "特性的Smectic液晶在从非倾斜SmA相过渡到倾斜SmC相时,最大层收缩率为±1%。我们在此表明,根据已建立的结构-性能关系,通过调整SmA促进元素和SmC促进元素之间的沮度,可以有计划地提高Smectic液晶的 "类德弗里斯 "特性。
