摘要

控制光学薄膜的双折射是制造薄型双折射光学器件的当务之急。本文合成了具有 4-甲酰基苯甲酸（PA）和肉桂酸（CA）侧基的新型光对准液晶共聚物（PLCPs），这种共聚物具有很高的光活性和方向可控性。此外，用 2-氨基芴（AF）处理曝光的薄膜，使 PA 与 AF 原位缩合，形成具有高固有双折射的希夫碱。光对准薄膜的双折射可控制到 0.45，而不会干扰光诱导的取向结构。

Birefringence and Orientation Direction Control of Photoalignable Liquid Crystalline Copolymer Films Based on In Situ Modification of Mesogenic Groups.

Controlling the birefringence of optical films is imperative to fabricate thin birefringent optical devices. Here, new photoalignable liquid crystalline copolymers (PLCPs) with 4-formylphneyl benzoate (PA) and cinnamic acid (CA) side groups are synthesized, which attain high photoreactivity and controllability of the orientation direction. Additionally, the exposed films are treated with 2-aminofluorene (AF) for an in situ condensation of PA with AF to form a Schiff base with a high inherent birefringence. Birefringence of the photoaligned film can be controlled up to 0.45 without disturbing the photoinduced orientation structure.
