我们报告了一种近晶型液晶，其中分子取向的倾斜远离层正常的近晶C相高达24度，发生最小的层收缩。这种特性，伴随着一个非常大的底层负热层膨胀系数，使手性近晶型电光电池的形成具有几乎理想的“书架”层的几何形状，从由收缩产生的V形层结构的复杂性自由。
We report a smectic liquid crystal in which a tilt of the molecular orientation away from the layer normal in the Smectic C phase of up to 24 degrees occurs with minimal layer contraction. This characteristic, accompanied by an exceptionally large underlying negative thermal layer expansion coefficient, enables the formation of chiral smectic electro-optical cells having nearly the ideal 'bookshelf' layer geometry, free from the complexities of the chevron layer structure produced by contraction.
