研究了以4-氧苯甲醛侧基(1)和单体4-甲氧基苯胺(2)复合的非光反应性聚甲基丙烯酸酯为原料制备可光对准薄膜的方法。a1 /2复合薄膜的制备和退火过程形成了光可对准的苯胺-苄基苯胺（NBA）侧基，而在线偏振（LP） 365 nm光照射下形成的薄膜诱导了NBA侧基的充分分子重取向。此外，在a1薄膜上涂上图案涂层和随后的LP光曝光产生图案分子取向，并结合控制双折射。
Facile fabrication of a photoalignable film from a nonphotoreactive polymethacrylate with 4-oxybenzaldehyde side groups (1) and a monomeric 4-methoxyaniline (2) composite is investigated. A1/2composite film fabrication and the annealing process form photoalignableN-benzylideneaniline (NBA) side groups, while the linearly polarized (LP) 365 nm light exposure to the resultant film induces sufficient molecular reorientation of NBA side groups. Furthermore, patterned coating of2on a1film and subsequent LP light exposure generate a patterned molecular orientation combined with controlled birefringence.
