将高度一级硅烷端基二氟三联苯液晶添加到具有向列相到近晶-C相变的三氟三联苯主体中，以增加其一级性质，实现更高的锥角并降低其温度依赖性。添加剂浓度的增加导致向列相线性减少并最终消失。以 35% 的浓度注入近晶 A 相，使转变发生二阶。混合物的光学研究表明锥角的最高值对浓度的依赖性很小。原始主体表现出一阶锥角行为，并用于制造扭曲的 FLC 器件。
Highly first order silane end-group difluoroterphenyl liquid crystal was added to trifluoroterphenyl host with a nematic to smectic-C phase transition to increase its first order nature, achieve a higher cone angle and reduce its temperature dependence. Increasing concentration of the additive, caused a linear decrease and eventual disappearance of the nematic phase. A smectic-A phase was injected at 35% concentration, making the transition second order. Optical studies of the mixtures showed little dependence of the highest value of cone angle on concentration. The original host showed first order cone angle behavior and was used to fabricate a twisted FLC device.
