我们在摩擦聚酰亚胺（PI）取向层上真空沉积制备了取向铜-酞菁（CuPc）薄膜。结果表明，α型CuPc微晶的b轴方向随PI层厚度的变化而变化，即b轴垂直于摩擦薄PI层的摩擦方向，而与摩擦厚PI层的摩擦方向几乎完全对齐。通过α型CuPc的高二向色比（约4）和原子力显微镜观察到的高取向针状微晶，证实了厚PI层上的取向结构。
We have fabricated oriented copper-phthalocyanine (CuPc) films by vacuum deposition on rubbed polyimide (PI) alignment layers. It was found that the b-axis of α-type CuPc microcrystals changes its direction depending on the thickness of PI layers, namely, the b-axis is perpendicular to the rubbing direction on a thin rubbed PI layer but is almost perfectly aligned to the rubbing direction on a thick rubbed PI layer. The oriented structure on a thick PI layer was confirmed by a high dichroic ratio of about 4, which is expected in the optical absorption of α-type CuPc, and by highly oriented needle-shaped microcrystals observed by atomic force microscopy.
