Polymeric compounds of general formula (I) where X, X1, X2 are independently straight or branched chain C1-16 alkyl, halogen and H; (a) is a suitable mesogenic group; Z=single covalent bond, oxygen CO2, OCO; n=1-20; Y=oxygen, CO2, OCO, CH2, CHOH, CH2O; m=3-10,000. The compounds are liquid crystal polymers useful in liquid crystal devices, sensors, and in non-linear optical devices. The compounds are prepared by polymerization of the oxitane monomer to obtain the side-chain liquid crystalline polyoxitane compound. In this way the mesogenic groups are spaced on every fourth carbon atom in the polymer chain allowing greater mobility for the mesogenic group.
通式(I)的聚合物化合物,其中X、X1、X2独立地为直链或支链C1-16烷基、卤素和H;(a)是合适的介向基团;Z = 单个共价键、氧CO2、OCO;n = 1-20;Y = 氧、CO2、OCO、CH2、CHOH、CH2O;m = 3-10,000。这些化合物是液晶聚合物,可用于液晶装置、传感器和非线性光学装置。通过氧杂环单体的聚合来制备侧链液晶聚氧杂环化合物。通过这种方式,介向基团在聚合物链上的每四个碳原子上间隔,从而使介向基团具有更大的运动性。
