Hydrazide-based non-symmetric liquid crystal dimers were synthesized. The liquid crystalline properties were investigated by differential scanning calorimetry (DSC), polarizing optical microscopy (POM), and powder X-ray diffraction (XRD). These non-symmetric liquid crystal dimers are evidenced to display the monolayer smectic C phase. The effects of the lateral intermolecular hydrogen bonding as well
合成了基于肼的非对称液晶二聚体。通过差示扫描量热法(DSC),偏振光学显微镜(POM)和粉末X射线衍射(XRD)研究了液晶性质。这些非对称液晶二聚体被证明显示出单层近晶C相。讨论了横向分子间氢键以及末端烷基链和间隔基的长度对中间相的影响。我们的研究表明,酰肼基团之间的分子间氢键和微偏析效应是形成单层近晶C结构的驱动力。版权所有©2007 John Wiley&Sons,Ltd.
