  Topological Ferroelectric Bistability in a Polarization-Modulated Orthogonal Smectic Liquid Crystal

  摘要：

  We report a bent-core liquid crystal (LC) compound exhibiting two fluid smectic phases in which two-dimensional, polar, orthorhombic layers order into three-dimensional ferroelectric states. The lower-temperature phase has a uniform polarization field which responds in an analog fashion to applied electric field. The higher-temperature phase is a new smectic state with periodic undulation of the polarization, structurally modulated layers, and a bistable response to applied electric field which originates in the periodically splay-modulated bulk of the LC rather than by surface stabilization at the cell boundaries.

  This invention relates to asymmetric haxtic-type reactive mesogen compounds and their preparation methods. More specifically, it pertains to novel asymmetric haxtic-type reactive mesogen compounds with a benzene ring of 5 (5-ring) and fluorine substituents on one end of the benzene. The asymmetric haxtic-type reactive mesogen compounds of the present invention have excellent liquid crystal molecular orientation characteristics, free from optical defects such as light leakage, suitable for application in vertical alignment (VA) mode, and can be used as source materials for achieving next-generation low-voltage driving and high-speed response displays.
