Triazine ring based polymers for photoinduced liquid crystal alignment introduces photoactive groups for inducing, reinforcing, improving and preserving liquid crystal alignment, for example photoreactor such as cinnamate, coumarin, chalcone and maleimide, as a chain to have at least one photoactive group. One of the photoactive groups can experience Fries rearrangement which induces liquid crystal alignment, and other groups can experience photodimerization, photoisomerization, photocrosslinking or photodegradation to reinforce, change or preserve the generated alignment.
基于三嗪环的聚合物用于光致液晶取向,引入光活性基团用于诱导、加强、改善和保持液晶取向,例如光反应器,如肉桂酸酯、香豆素、查尔酮和马来酰亚胺,作为链的至少一个光活性基团。其中一个光活性基团可以经历弗里斯重排,诱导液晶取向,其他基团可以经历光二聚、光异构化、光交联或光降解,以加强、改变或保持产生的取向。
