Novel asymmetrical single- and double-chiral liquid crystal diads are reported, where diad III-D exhibited the widest range of BPI about 31 °C. Large biaxiality and dipole moment of the bent molecule are useful to extend the BP temperature range.
报道了新型的不对称单手性和双手性液晶二聚体,其中二聚体III-D的B
PI范围最广,约为31°C。弯曲分子的大双轴性和偶极矩有助于扩展BP温度范围。
