合成了一种具有弯曲核心分子结构的手性非外消旋酯(见图)，并对其介晶行为和物理性能进行了评价。该化合物具有低熔点，手性近晶C相，温度范围宽，并且在很低的自发极化下表现出异常高的倾角。然而，该化合物最重要的方面是近晶A相的螺旋结构。
A chiral, nonracemic ester with a bent‐core molecular architecture (see figure) has been synthesized and evaluated for mesomorphic behavior and physical properties. The compound has a low melting point, a chiral smectic C phase with a wide temperature range, and it shows an unusually high tilt angle at a very low value of spontaneous polarization. However, the most significant aspect of the compound is the helical structure of the smectic A phase.
