The fabrication of a single-crystalline thin film of non-peripheral octahexyl-phthalocyanine (C6PcH₂) was realized by performing a tetrahydrofuran (THF) vapor treatment on a the spin-coated film. The solution-mediated polymorphic transformation of C6PcH₂ was promoted in the THF vapor, and a single-crystalline thin film with α-phase crystal grew in the thin film when setting an appropriate temperature. The thin film exhibited optical anisotropy, such as a high dichroic ratio, and the color of the transmitted light varied from green to transparent depending on the polarization direction. The molecular packing structure on the substrate was determined by X-ray diffraction and polarized absorption measurements.

通过在旋涂膜上进行四氢呋喃（THF）蒸气处理，可以实现非周边八己基-酞菁（C6PcH ₂）单晶薄膜的制造。在THF蒸气中促进了溶液介导的C6PcH _2的多晶型转变，并且当设定适当的温度时，具有α相晶体的单晶薄膜在薄膜中生长。薄膜表现出诸如高二向色比的光学各向异性，并且透射光的颜色根据偏振方向从绿色变为透明。通过X射线衍射和偏振吸收测量来确定在基板上的分子堆积结构。
