Compounds of formula (I) may be used as alignment layers in liquid crystal devices wherein X1-5 are idependently selected from H, F, CN, phenylene, C1-10 alkyl, whereby when X1=X2, then X1,2=H and when X3=X4, then X3,4=H, S1-3 are spacer units, PG1-3 are photoisomerisable/dimerisable groups.
公式(I)的化合物可以用作液晶器件中的取向层,其中X1-5分别选自H、F、CN、苯基、C1-10烷基,当X1=X2时,X1,2=H,当X3=X4时,X3,4=H,S1-3为间隔单元,PG1-3为光致异构/二聚基团。
