Polymerizable tolanes of formula I
wherein P, Sp, X, n, A1, A2, Z1, Z2, m1, m2, L1, L2, r and R have the meanings defined herein, polymerizable liquid crystal compositions comprising at least one compound of formula I, linear or crosslinked liquid crystal polymers obtainable from these compounds and compositions, are suitable for use in optical elements such as polarizers, retardation and compensation films, alignment layers, color filters or holographic elements. They are also suitable for use in liquid crystal displays such as PDLC, polymer gel or polymer stabilized cholesteric texture (PSCT) displays, as well as for use in adhesives, synthetic resins with anisotropic mechanical properties, cosmetics, diagnostics or liquid crystal pigments, for decorative and security applications, and for nonlinear optics or optical information storage.
公式I中的可聚合的Tolane,其中P、Sp、X、n、A1、A2、Z1、Z2、m1、m2、L1、L2、r和R的含义在此定义,至少包含一个公式I化合物的可聚合液晶组合物,可获得从这些化合物和组合物中得到的线性或交联液晶聚合物,适用于用于光学元件,如偏振器、延迟和补偿膜、定向层、彩色滤光片或全息元件。它们也适用于用于液晶显示器,如PDLC、聚合物凝胶或聚合物稳定的胆甾醇纹理(PSCT)显示器,以及用于粘合剂、具有各向异性机械性能的合成树脂、化妆品、诊断或液晶颜料,用于装饰和安全应用,以及用于非线性光学或光学信息存储。
