Uniaxially oriented thin films of pentyl-substituted phthalocyanine (C5PcH₂) were prepared by bar-coating, and the molecular alignment and crystal structure were measured by the grazing incidence wide-angle X-ray scattering technique. α-type and β-type crystals in the thin film selectively grew by using the seed crystals of α-type and β-type C5PcH₂, respectively. Non-reported crystal structure appeared when the thin film was fabricated without seed crystals, and the molecular packing structure was estimated from the peak intensity ratio of the X-ray diffraction image.
