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. |
