系统研究了含氟芳香族聚酰亚胺4，4-（六氟异亚丙基）二邻苯二甲酸酐2，3，5，6-四甲基-1，4-苯二胺（6 FDA-TeMPD）的光反应性和光取向敏感性。该聚酰亚胺具有高耐热性、在极性溶剂中的高溶解性、高光学透明性和低折射率。通过控制浇铸溶剂的种类和干燥条件，得到了不同分子有序结构的6 FDA-TeMPD聚酰亚胺。在高挥发性制备条件下获得的聚酰亚胺的光反应性高于在低挥发性条件下获得的聚酰亚胺。的光反应性表现出更高的依赖性的类型的铸造溶剂比热处理温度。荧光光谱表明，在254 nm线偏振紫外光照射下，聚合物的缩合反应增强。另一方面，光取向灵敏度不依赖于聚合物的内聚性，而是取决于聚酰亚胺膜中残留的溶剂痕迹。此外，通过减少聚合物膜中残留溶剂的量，可以提高光取向灵敏度。
The photo reactivity and photo alignment sensitivity of a fluorine-containing aromatic polyimide, 4,4-(hexafluoroisopropylidene) diphthalic anhydride 2,3,5,6-tetramethyl-1,4-pheny lene diamine (6FDA-TeMPD), were systematically investigated. This polyimide has high heat resistance, high solubility in polar solvents, high optical transparency, and low refractive index. Different molecular ordering structures of 6FDA-TeMPD polyimide were obtained by controlling the type of casting solvent as well as the dry conditions. The photo reactivity of the polyimide obtained under highly volatile preparation conditions is higher than that obtained under lowly volatile conditions. The photo reactivity showed higher dependency on the type of casting solvent than on the heat treatment temperature. The fluorescence spectra show that the polymer condensation increased under 254 nm linearly polarized ultraviolet irradiation. On the other hand, the photo alignment sensitivity did not depend on the polymer cohesiveness, but rather on the residual solvent trace in the polyimide film. Moreover, the photo alignment sensitivity can be increased by reducing the amount of residual solvent in the polymer film.
