We have designed, synthesized and evaluated the physical properties of new fluorinated phenyltolane based chiral liquid crystal materials with 2-methylbutyl terminal chain. The 2- or 2,6-fluorosubstitution in combination with the phenyltolane core brings surprising improvement of mesomorphic properties. The investigated compounds are characterized by a broad temperature range of the cholesteric (chiral
我们已经设计,合成和评估了具有2-甲基丁基末端链的新型氟化苯基甲苯基手性液晶材料的物理性能。2-或2,6-氟取代基与苯基tolane核心相结合,带来了令人惊奇的介晶性能改善。所研究的化合物的特征在于胆甾型(手性向列型N *)相的温度范围宽,熔融温度极低,并且易于在近红外区进行选择性反射的热控制。适中的螺旋扭曲力β,高的光学各向异性和蓝相的来源,使这些化合物对胆甾型混合物配方具有吸引力。
