chiral alkyl group, synthesized by a palladium-catalyzed coupling reaction, provide a new series of liquid crystalline materials which form chiral smectic C (SmC*) phases exhibiting ferroelectric properties. Mesomorphic properties of the compounds composed of three aromatic rings is strongly affected by the position of an acetylenic linkage and the direction of an ester linking unit. The effect of variations
通过钯催化偶联反应合成的具有手性烷基的二苯乙炔同系物提供了一系列新的液晶材料,其形成具有铁电性质的手性近晶 C (SmC*) 相。由三个芳环组成的化合物的介晶性质受炔键位置和酯键单元方向的强烈影响。已经系统地研究了末端链长的变化对近晶 A (SmA) 和 SmC* 两个和三个芳环系统的热稳定性的影响。
