formed by achiral bent-core (BC) molecules associated with chirality and polar order exhibit electro-optically switchable lamellar and columnar phases, and nematic phases which could be biaxial or polar. As polymeric LCs could have application in photonics and non-linear optics, BC monomers having naphthalene moiety in the side arms and linked with terminal double bonds as polymerizable functional groups
摘要 由具有手性和极性顺序的非手性弯曲核 (BC) 分子形成的液晶 (LC) 表现出电光可切换的层状和柱状相,以及双轴或极性的向列相。由于聚合物液晶可用于光子学和非线性光学,因此合成了侧臂具有萘部分并与末端双键连接作为可聚合官能团的BC单体。通过光学、X 射线衍射、介电和电光研究,研究了具有中心苯环的 6B2 和具有中心萘部分的 6N2。将描述可以解释所展示的相变的可能原因。
